How Engineers Can Cope Effectively to Reduce Burnout During COVID-19

Wednesday, August 12th, 2020

In the current pandemic situation, many people have been forced to shift their work into their homes and to learn ways to organize and execute that they aren’t used to. Considering this, health experts are warning about the long-run effects of working remotely including burnout and stress. At this point, it can also have an impact on a person’s mental and emotional well-being, creating a state of delicacy born from over-tiredness and frustration.

However, this can be difficult even when we’re not experiencing a pandemic. With the growing stress day by day, burnout is occurring at an alarming rate with people unable to separate home from work, the magnified burden of keeping everything on and heightened on-call loads, and the strain on communication. For product and engineering teams, development now occurs in isolation; meetings are held via email, messaging app or calls; and decisions are made asynchronously. This, as a result has resulted in burnout which needs to be reduced in such crisis. Here, in this blog you will get to know about some important ways to combat this and keep yourself and your team from burning out.

Reasons Why Companies Should Be Concerned for Burnout

When you were at the office you were completely working. But now those lines are blurred, or nonexistent. This is a new kind of stress that most of us have never before experienced while working from home. There’s now an expectancy that we should be going “above and beyond” with our jobs, something that often translates into working longer hours. The top reasons which is why it is a major concern for companies are-

  • Decreased Productivity
  • High Turnover Rate
  • Low Employee Engagement
  • Negative Health Impacts

Not only in work from home situation, but also burnout is more common within organizations. It can’t be measured easily by the number of hours worked or the amount of sleep one gets. It is more often related to extended pressure and to operating from a place where you start every day feeling backside, fighting against quicksand. It can cause exhaustion, trouble sleeping and an inability to focus. However, this doesn’t mean you’re not good at your job or capable of remote work. Or else, this is likely a version of burnout that none of us have experienced before.

As mentioned, It is not so easy to overcome but there are some ways to combat this and keep yourself and your team from burning out.

  • Encourage Autonomy and Asynchronous Communication

You can communicate to your team so they know when you’re online and available, by sharing an accurate calendar noting when you’re busy with personal needs or “in-office.” In addition, you can help other teammates struggling with vertical schedules by asking “can this be done asynchronously?” If a meeting isn’t necessary, prefer writing an email instead.

  • Follow Agile Workflow

Engineering teams can amend the stress that leads to burnout by actively and visibly reinforcing the value that the team is delivering. An agile workflow can be a great way to do this. The prime advantage is that the team can avoid an endless push by incrementally releasing features and achieving milestones.

  • Use of Feature Flags

Organizations should use feature flags feature as it allow engineering teams to operate with greater autonomy, as code developed by one engineer can be released before its dependencies are completed. They allow for enabling the code safely and incrementally, minimizing the stress of releases and giving teams an escape hatch should an issue occur.

  • Unplug and Relax

Last but not the least, its important to take time and relax. If you’re not on call, try to separate work and life by minimizing time spent checking your emails or responding to Slack messages. To help you avoid this enticement, create a separate desktop on your laptop or folder in your phone for work and home, and turn off work notifications when you’re not working.

Conclusion

These tips won’t solve all the problems, but they can help provide a bit of buffer against burnout and improve your team’s morale during a trying, emotional, and difficult time. By taking some time to recognize the signs of burnout and addressing it will help you become more satisfied with your job, lead to a growth mind-set and help you become more successful in your personal as well as professional life.

As we all know, the coronavirus pandemic has globally disrupted people’s life and lifestyles. Governments have enforced lockdowns to curb the spread of the virus. Work from home is the new reality for many businesses. Even, schools and colleges are conducting online classes. In fact, social distancing is the new norm at grocery stores. People are getting used to this kind of change and they are aware that how much this virus is dreadful for them. In addition, one of the major fact is that the COVID-19 will have a lasting effect not only on our daily lives but also on our economy, and things are not likely to return to pre-pandemic norms sooner.

In such case of lockdown, there is a unique focus back on the urgent need to adopt digitization and modern technology tools to not only get through the pandemic but to also sustain a competitive market and be prepared for future crisis.

Technology is Helping Us More Than You Realize

In the past few months, there is surge in adoption of various advanced technologies. The big examples are drones for food delivery and robots for automation to COVID-19 contact tracing apps, and online education learning platforms. This is not the end! This blog discusses some of the tech trends that are likely to see a surge in adoption post COVID-19.

Artificial Intelligence (AI)

AI is playing a massive role in helping us all get through the pandemic and it will see a greater adoption after the pandemic is over. AI will be particularly useful for those within retail and supply chain industries. Through machine learning and advanced data analytics, AI will help these companies detect new purchasing patterns and deliver a greater personalized experience to online customers.

Most importantly, big tech firms like Facebook, Twitter, Instagram, and WhatsApp, are leveraging the power of AI to decrease the spread of COVID-19 related misinformation online, mobile app developers are building AI-powered apps that can help screen people for COVID-19 symptom. For companies looking to restart their office, Amazon’s new AI-powered tracking system will encourage employees to maintain social distancing.

Internet of Things (IoT)

IoT has played a significant role in successfully leading the battle against the coronavirus pandemic. In the coming years, IoT will transform the user experience profoundly, providing opportunities that weren’t possible before. The biggest example of IoT being used during the pandemic is that of drones that are not only helping deliver food and other necessities but are also helps keep check on containment zones and congested areas to mitigate the spread of the virus.

Moreover, some other examples include connected thermometers and remote monitoring of patients using IoT-enabled device. At present, remote monitoring of patients is helping offer relief to hospital doctors and staff by limiting their face-to-face interaction with patients who are infected.

Cybersecurity

It has been analyzed that coronavirus pandemic saw a massive surge in cyber-attacks (such as ransomware, email campaigns, phishing, etc) and data breaches. The current situation of lock-down, when thousands of people are forced to work remotely, volumes of private data may become totally vulnerable or not protected in a proper way. This is why companies are likely to boost their cybersecurity plans to make sure their sensitive corporate data is not compromised in the coming years because of certain security loopholes.

VR/AR

As we know, everyone is spending a lot of time in their home because of lockdown, which has increased the number of people using #VR headsets to play video games, explore virtual travel destinations and partake in online entertainment. For this, they’re also using this technology to seek human interaction through social VR platforms.

Also, businesses have been experimenting with VR platforms to train employees, hold conferences, collaborate on projects, and connect employees virtually. Now that businesses and consumers know the extent to which this technology can be used, we are likely to see more virtual conferences and human interactions as our new normal sets in.

Voice User Interface (VUI)

Nowadays, consumers are becoming increasingly concerned that their mobile devices can spread coronavirus because it has been used and placed at so many places in a day. As the fear of spreading germs grows, so will the use of voice tech in forms of voice user interface (VUI), which can reduce the number of times one touches any surface, including our mobile devices. Almost 80% of our communications done using verbal communication, that’s why voice usage will continue to increase in the coming times as well.

Summing It Up

These emerging technological trends will see a greater acceleration in adoption in the world after the COVID-19 pandemic. It would be better for industries and businesses to adapt these changes which will later help them alot. So, get ready to implement these technologies and prepare yourself for a better future!

Importance of APIs in the World of Social Media

Tuesday, June 30th, 2020

You have probably heard of the acronym tossed around in recent years. API is the acronym for Application Programming Interface which is a set of instructions, standards, or requirements that enables a software or app to employ features/services of another app, platform, or device for better services. Concisely, it’s something that lets apps communicate with each other. One of the major aspects of API is that it has made the internet experience much more pleasant for every person. The acronym has helped you compare the best prices for flights, allowed you to embed a map into your store’s website, and even seamlessly processed your credit card payments. If you want to explore more of it, then this blog will give an overview of APIs and how they relate to social media platforms.

Role of APIs for Social Media

Social media has exploded in recent years. Today, the number of people on social media has grown to nearly 3 billion, and the numbers are projected to continue their upward trend. As we know, there are numerous platforms, from Facebook, Instagram to Twitter, Imgur to Foursquare, and more, cater to a remarkable range of digital interactions to people around the world. 

APIs make social media possible and they are crucial to successfully exchanging all of this information and delivering the experience that users expect. Without APIs, it would be difficult for your website to link your Facebook page or Twitter account to your website or to combine your Google Plus account to your blog posts in order to promote your authorship reputation. In like manner, you will not be able to use the Google Analytics tool in auditing and optimizing your e-commerce website for better search performance. The social media marketing tools that are used in encouraging businesses are powered by APIs. As far now, there are many marketing values that are derived from social media APIs which include but not limited to the following:

  • Showing ad campaigns to your site as a publisher.
  • Application development to expand the benefits of using marketing tools.
  • Displaying social media buttons to optimize the social shares of your post.
  • Seamless launching of an email marketing campaign using APIs for customer subscription lists and ad campaigns.
  • Tracking down the data analytics information from your website to the analytic monitoring tool or software.

Big Examples of Social Media API Functionalities

As mentioned above, APIs are being used in countless ways by every social media platform today. Here are a few popular examples:

Facebook Graph API:

At present, Facebook is the world’s largest social media platform, with more than 2.4 billion active users worldwide. The Facebook Graph API is an HTTP-based API that provides the main way of accessing the platform’s data. Third-party developers and creators use this tool to retrieve information such as username, email, birthday, and hometown of users. Besides, popular chains such as Subway and Starbucks use the Graph API to collect user information to assist in their marketing and advertising strategies.

Twitter Ads API: 

The Twitter API mainly allows you to add Twitter functionalities to your application. Moreover, the Twitter Ads API is a key part of their business; it not only helps promote Twitter accounts but also allows organizations to launch their scheduled advertising campaigns. With the help of API, marketers can reach out to people of a certain age group from a certain city. From one ad account, an organization can roll out about 200 active advertisement campaigns.

Imgur API: 

Imgur is another amazing social media platform where people share entertaining images. It has a global user base with high engagement, and these users are particularly interested in technology, video games, food, and music. Brands outside of Imgur can utilize its API functionality to expose these users to new gaming and tech items and products. Currently, Imgur offers its third version of APIs which use OAuth 2.0. Therefore, you won’t have to encrypt your requests, but simply send them to https:// via SSL/TLS. 

LinkedIn API:

LinkedIn can be described as the world’s number-one social network for business users. It was established in 2003, and currently serves millions of users in more than 200 countries worldwide. LinkedIn also offers API access to developers (RESTful), so that all contacts, jobs, relationships, companies, and interactions would be displayed by third-party providers. Likewise, there are many more: Instagram, Reddit, Snapchat, and other social media brands all have created APIs. These APIs will act as potent technologies supporting the ever-expanding promise of social media.

Conclusion

With the aforementioned information, I hope you will find an API that you can use to add versatile social engagement capabilities to your applications! For more information, you can connect with our business consultants. 

Waterfall Vs Agile Methodology

Monday, June 29th, 2020

What is Waterfall methodology?

Waterfall Model methodology which is also known as Linear Sequential Life Cycle Model. The Waterfall Model followed in sequential order, and so the project development team only moves to the next phase of development or testing if the previous step completed successfully.

What is the Agile methodology?

Agile methodology is a practice that helps continuous iteration of development and testing in the software development process. In this model, development and testing activities are concurrent, unlike the Waterfall model. This process allows more communication between customers, developers, managers, and testers.

Advantages of Waterfall Model:

  • It is one of the easiest models to manage. Because of its nature, each phase has specific deliverables and a review process.
  • It works well for smaller size projects where requirements are easily understandable.
  • Faster delivery of the project
  • Process and results are well documented.
  • Easily adaptable method for shifting teams
  • This project management methodology is beneficial to manage dependencies.

Advantages of the Agile Model:

  • It is a focused client process. So, it makes sure that the client is continuously involved during every stage.
  • Agile teams are extremely motivated and self-organized so it is likely to provide a better result from the development projects.
  • Agile software development method assures that quality of the development is maintained
  • The process is completely based on incremental progress. Therefore, the client and team know exactly what is complete and what is not. This reduces risk in the development process.

Limitations of Waterfall Model:

  • It is not an ideal model for a large size project
  • If the requirement is not clear at the beginning, it is a less effective method.
  • Very difficult to move back to make changes in the previous phases.
  • The testing process starts once development is over. Hence, it has high chances of bugs to be found later in development where they are expensive to fix.

Limitations of Agile Model:

  • It is not a useful method for small development projects.
  • It requires an expert to make important decisions in the meeting.
  • Cost of implementing an agile method is little more compared to other development methodologies.
  • The project can easily go off track if the project manager is not clear what outcome he/she wants.

Conclusion:

Agile and Waterfall are very different software development methodologies and are good in their respective way.

However, there are certain major differences highlighted below –

  • Waterfall model is ideal for projects which have defined requirements, and no changes are expected. On the other hand, Agile is best suited where there is a higher chance of frequent requirement changes.
  • The waterfall is easy to manage, sequential, and rigid method.
  • Agile is very flexible and it is possible to make changes in any phase.
  • In the Agile process, requirements can change frequently. However, in a waterfall model, it is defined only once by the business analyst.
  • In Agile Description of project, details can be altered anytime during the SDLC process which is not possible in Waterfall method.

Java & JavaScript

Monday, June 29th, 2020

What is the difference between Java and JavaScript?

The Internet is flooded with statements like Java and Javascript are similar to cars and carpet. But it does not hold true anymore.

It often happens that programmers get confused between Java and JavaScript. Thinking both Java and JavaScript to be the same.

As both Java and JavaScript refer to the same OOP language and share the same control structures and operators. But when you will learn them individually, you will get to know they are completely different from each other.

Java

Java is a popular object programming language invented by James Gosling and developed by Sun Micro-Systems. It is a general-purpose high-level programming language created in the year 1995.

James Gosling initially developed Java in Sun Micro-Systems (which was later merged with Oracle Corporation). Java is a set of features of C and C++. It has obtained its format from C, and OOP features from C++.

Originally Java was named as OAK but later it changed into Java. With its virtual machine platform, it allows you to create compiled programs that run on nearly every platform.

Benefits

  • Java is platform-independent and flexible in nature. The most significant feature of Java is to run a program easily from one computer system to another. 
  • It can also be distributed among servers and clients in a network.
  • It can be used in a wide variety of computing platforms to enterprise servers and supercomputers.
  • It can be used to make mobile applications, web and desktop applications, games and much more.

JavaScript

JavaScript was developed by Brendan Eich in 1995, which appeared in Netscape, a popular browser of that time.

JavaScript is a lightweight programming language of HTML and Web used to make web pages interactive. As a multi-paradigm language, it supports event-driven, functional, imperative, and programming styles.

JavaScript is a very powerful client-side scripting language. JavaScript is used mainly for enhancing the interaction of a user with the webpage. In other words, you can make your webpage livelier and more interactive, with the help of JavaScript.

It was first known as Live Script, but later Netscape changed its name to JavaScript.

Benefits

  • Adding interactive behavior to web pages.
  • Developers can use various JavaScript frameworks for developing and building web and mobile apps.
  • Beyond websites and apps, developers can also use JavaScript to build simple web servers and develop the back-end infrastructure using Node.js.

Differences Between Java and JavaScript

It is a very common thought that both Java and JavaScript are the same. But the truth is there is nothing common between them except their name Java. Both are completely different and have nothing to do with each other. Their working, functionality, and capabilities all are very different.

List of key differences

If we traveled back in time, there would be a simple comparison like Java is a general-purpose coding language, and JavaScript is used on the web applications to make them interactive and animated. Now that JS has “grown-up,” the comparison is much more complicated here.

As Java has so many important features it is a most used programming language. Whereas JavaScript, on the other hand, possesses some features that Java lacks. JavaScript does not require any compiler or editor; it is considered as the easiest language to learn.

Thus, both Java and JavaScript carrying different features are equally important in their areas of requirement.

Conclusion

Both Java and JavaScript are different languages and have no similarity except the syntactic resemblance. After going through the above comparison between Java and JavaScript you can very well know about their differences and similarities. Java is a general-purpose language used for developing desktop or mobile or web-based applications.

On the contrary, JavaScript is a client-side scripting language used for designing the behavior and interactivity for web-based applications. However, both are very popular and effective while creating interaction between the user and the web page.

Test Driven Development(TDD)

Friday, June 19th, 2020

INTRODUCTION

Test Driven Development(TDD) is a software development process developed and discovered by Kent Beck. It is a technique where test code is written before production code. It is a technique that is used for designing as well as testing software. Basically, TDD is a process that turns requirements into very specific test cases. It is one of the core principles of extreme programming. It is referred to as test driven design. Unit tests and Refactoring are considered as components of TDD. It is not a one way or linear process.

To summarize Test Driven Development(TDD) is a proven technique to ensure effective unit testing. It consists of short development iterations. TDD is nothing but a technique of TFD (Test First Development) and Refactoring together. TDD promotes improved quality because extensive verification is performed.

TDD is a technique that discovers the mistakes upfront and prevents code with too many defects. The main benefit of using TDD is that one can write a high level of quality code much faster than without TDD because modifying the existing code with TDD is easy.

IMPORTANT PRINCIPLES OF TDD

Important principles of TDD are:

  • Write tests, then the code
  • Write a code only when test fails
  • write the code to make tests pass, Eliminate duplication

WHY TEST-DRIVEN DEVELOPMENT IS?

There are many constant changes in business requirements for software applications. Thus, making modification in a traditionally developed software application seems to be difficult. Because of this many organizations hesitate to make changes, thus affecting their overall success. TDD is thus indeed a solution to this because it makes developers easier to make the required modifications to the application without affecting the operations of the application.

The core objective behind using TDD is to implement smaller test cycles and achieve more agility in the process. With TDD, you start by creating the test cases for a new feature, write code required to pass the test, after that refactor the code to increase its sustainability. In TDD, automated tests are written before writing the code which helps to get fast confirmation on whether the code works as expected or not. TDD immersed as a reaction to waterfall development. It’s an incremental and evolutionary design technique.

STAGES OF TDD

There are three stages of TDD, see the details below:

Red Stage

Red stage consists of tests creation in which initially tests fail as code is not written or features may not be implemented. Therefore, any failure in this stage is not considered as a bug or defect.

Green Stage

Green stage consists of writing code in order to make the test pass. For writing code practices like “Keep it Simple (KISS) are recommended. The code written in this stage may not be of high quality and coding values are hard coded, but that can be refactored in the next stage.

Refactor Stage

Refractor stage consists of improving the quality of code without changing the actual behavior. While refactoring, duplicate code is removed, and any hardcoded data is parameterized in order to match the actual requirements. Any bad coding practices used are also cleaned up improving Readability, performance and maintainability. At the end of the refactoring process, the Existing test cases should still pass to ensure that the functionality has not been broken.

It is called Red/Green Refactor because the unit testing framework displays a red bar for failing and green bar for passing tests. TDD tests are executed in less than 10 mins.

BENEFITS OF TDD

  • TDD keeps the code clear and simple and improves the quality of code. It Ensures that the written code is covered by at least one test, thus increasing the level of confidence in the code.
  • TDD reduces the debugging time and Eliminates duplication of code.
  • TDD helps in complete understanding of requirements and provides the ability to modify the application with the changing business requirements.

DRAWBACKS OF TDD

  • Main drawback of using TDD is that Database and external files are not tested.
  • TDD seems to be Difficult for GUI (Graphical User Interfaces) & relational databases.
  • TDD requires additional time to write and maintain test cases.
  • TDD Tests can sometimes be incorrectly formulated or applied as a result unit tests do not perform as expected in real domain and Efforts are required to maintain test suites

LEVELS OF TDD

There are 2 types of TDD:

  • ATDD (Acceptance TDD)
  • TDD (Developer TDD)

Acceptance TDD

Acceptance TDD is the collaborative practice and advanced form of TDD. In this automated acceptance criteria are defined early in the development process. It focuses on external quality of software.

In scrum with the project manager to find out the acceptance criteria to achieve the requirements that the user stories represent. ATDD shows a clear picture of how the product will look.

Developers TDD

Developers TDD focus on specifying complete plans on a JIT (just in time) basis. In developer TDD, a simple developer test frequently referred to as unit test is written and then just enough production code to pass that test is written.

TOOLS FOR TDD AND ATDD

Tools for TDD

  • .Net – Nunit
  • Java – Junit
  • C++ – gunit
  • Python – Pyunit

Tools for ATDD

  • FitNesse
  • Selenium
  • Sahi
  • Frankenstein

DIFFERENCE BETWEEN NORMAL AND TDD APPROACH TO DEVELOP A SOFTWARE:

Normal Approach

Steps:

  • Write a code (logic) and compile it.
  • Write unit tests to test the code.
  • Run the unit tests to check if the logic is working or not.

TDD Approach

Steps:

  • Write unit tests.
  • Execute the tests (the test case will fail as there is no code written).
  • Write code to make sure the unit test compiles.
  • Execute the unit test and see if it passes or fails.
  • If it passes, then move on to the next unit test, else refactor and then execute.

DIFFERENCE BETWEEN NORMAL AND TDD APPROACH FOR TESTING A SOFTWARE

Normal Approach

  • Focus is on test case design
  • Generate the code and then write test cases based on that code

TDD Approach

  • More focus is on production code
  • Code is written for already created test cases.

HOW TDD HELPS TO AVOID SCOPE CREEP AND PREVENT BUGS

Scope creep can happen due to several reasons like lack of documentation, misinterpretation of project requirements, ineffective distribution of tasks etc.

TDD environment developers write unit tests to test a feature to be implemented. Therefore, avoids redundant code that wasn’t specified in the project requirement.

TDD is a unique agile approach which when followed properly results into 100% test coverage. TDD developers focus on preventing bugs rather than removing it later.

ROLE OF QA IN TDD

In TDD, developers use test cases to develop their code and execute test cases respectively. So, in TDD major dependency is on test cases. So, test cases with good coverage of requirements are more important for making TDD successful. It is an overall observation that QAs know the system much better than a developer as they test the system End-to-End. Therefore, it is required to involve the QA team from the beginning of the project. QA & developer should work together to create test cases. It helps developers to design better unit level test cases & QA can set up acceptance test cases that are at a higher level than unit test cases.

Tester’s knowledge of the system and the developer’s technical knowledge accomplished each other to help adding duplicate and invalid tests

Role of HR in driving the Agile Organizations

Thursday, June 11th, 2020

Nowadays, organizations consider strategic agility a revolutionary change for the business. Agile transformations modify the process of how people work, engagement with customers, and employee management. Businesses aim for efficiency, consistency, and productivity by actively managing the activities right from the top. They incorporate quality and standardized processes to forecast the requirements and design the systems to ensure the availability of resources at the right place and right moment.

For now, businesses need to quickly assemble and reassemble their employees in teams depending upon the evolving demands but, this won’t be enough to drive agility. The teams would be requiring more workers beyond the organizational boundaries like the Freelancers, Outsourcing Partners, and Strategic Partners. By adopting such an approach, businesses can more flexibly respond to rising opportunities and effective business operations.

During an Agile transformation, the teams become more concentrated towards the technology and process. However, creating an agile organization is a people-oriented effort. Ultimately, it is the people who are being asked to transform their thinking abilities, working process, and implement change. As a people-oriented method, it pays to include HR with commanding the charge and helping people adjust to the changes.

Successful Agile transformation recognizes the role of HR in executing change

As enterprises are reconfiguring their methods to make agility a top preference, however, the process will bring new challenges and responsibilities for the HR. Moreover, it will entirely transform the structured management of HR, and the techniques which they were implementing in their talent management & services. In this blog post, we will outline the parameters that HR need to adopt for effectively enabling agility:

Implementing science and fact-based analytics

For driving agility, HR should utilize the tools and empirical studies of data to perform analytics on their own workforces and use the resulting insights to make evidence based decisions regarding the workforce management.

Creating a learning organization

The HR practitioners should focus on assisting the workers often, creating new skill sets, and gaining new learning promptly. This will create a culture inclusive of continuous learning, peer to peer learning, fostering informal, and recruiting the people with a keen ability to learn.

Talent Management Processes

Instead of viewing people as a series of fragmented parts, for example, a portion that needs to be hired, a portion that requires learning, a portion that requires progress on a career path, HR practitioners should look at the whole employee and their requirements, strategically and customize accordingly.

An Agile Operating Model for HR increasing business focus, efficiency and effectiveness

HR in Agile Organization

Bottom Line

It is very important to involve HR at the initial stage if you have just started with the agile transformation. However, HR should also participate in conducting talent audits of the company to explore the skills and knowledge that is lacking. This would be very effective as HR will create a hiring plan accordingly to bridge the gaps.

In addition, auditing the talent and modifying the recruitment plans before the full adoption of Agile, will enable the organizations to staff and skill the teams proficiently. HR with clearly defined career paths can lead to increased talent retention rates which will benefit the organization. To match up with the pace of agile transformations, HR requires to correctly reinvent themselves and the practices they support.

Manual Vs Automation Testing

Thursday, June 11th, 2020

In this article we are going to talk about advantages of Automation Testing over Manual testing.

What is Manual Testing and Automation Testing?

Manual testing is performed by hand. Quality Assurance (QA) specialists ensure that applications work properly by following conditions written in test cases. Despite its primitive nature, manual testing is still important, as certain functionality simply cannot be automatically tested. For example, wearables and mobile devices can require field testing in a physical environment. Mobile applications often undergo ‘monkey tests’ that detect bottlenecks during unpredicted stressful conditions. For instance, what happens if a user forgets a mobile device in their pocket with an application running and they tap the screen unintentionally? Is it possible that they’ll crash the app? Only manual testing can account for these scenarios.

Automation testing is a Software testing technique to test and compare the actual outcome with the expected outcome. This can be achieved by writing test scripts or using any automation testing tool. Test automation is used to automate repetitive tasks and other testing tasks which are difficult to perform manually

Now let’s discuss automated and manual testing in detail.

Automation Testing:

As per Industry standards and specialization our QA team automates the following types of testing:

Unit Testing is a level of software testing where individual units/ components of the software are tested. The purpose is to validate that each unit of the software performs as designed. A unit is the smallest testable part of any software. It usually has one or a few inputs and usually a single output.

Functional Testing is Software testing performed in order to detect the actual performance of an application’s functional requirements. Functional testing usually considers accuracy, interoperability, compliance, security, and suitability.

Regression Testing is defined as a type of software testing to confirm that a recent program or code change has not adversely affected existing features. Regression Testing is nothing but a full or partial selection of already executed test cases which are re-executed to ensure existing functionalities work fine

Graphical user interface (GUI) testing of software interfaces to check if the GUI meets all requirements.

These are the most common types of testing that we automate. Manual testing requires people and time, while automated testing reduces the demand on both resources. Also, automatic tests eliminate the risk of human error, making code more reliable. Now let’s see what tasks we can solve by automated testing.

Why you need automated testing?

Automated Testing Saves Time and Money

Software tests have to be repeated often during development cycles to ensure quality. Every time source code is modified software tests should be repeated.  Automated software testing can reduce the time to run repetitive tests from days to hours.

To handle repetitive tasks. If you’re constantly adding the same features or executing the same operations in a project, then the flexible nature of automated tests can be a great time saver.

To eliminate human error. Since automated tests are powered by tools and scripts, the chance of missing a bug or a defect decrease. This makes the testing process more reliable and time efficient.

For advanced GUI testing. Automated GUI tests detect and record differences in behavior between platforms — for example, across different web browsers or operating systems. Also, automated GUI testing effectively finds regression errors.

To test load and performance. There’s essentially no manual alternative for testing load and performance. Automated tests simulate hundreds and thousands of simultaneous users.

Why do you need Manual Testing?

Despite the seemingly broad coverage of automated testing, manual testing shouldn’t be underestimated. In fact, you have to test software manually before you run automated testing. Even though manual testing requires much effort, without it you cannot be sure that automation is possible. One of the key testing principles is that 100% testing automation is impossible. Manual testing is still necessary.

Let’s see which tests cannot be automated (or would take too much effort to automate):

Ad hoc testing is executed without preparation and writing test cases. During ad hoc testing, a QA specialist randomly tests the functionality of the system; his aim is to be creative, “break” the system and discover flaws.

Exploratory testing is defined as simultaneous learning, test design, and test execution. It is an approach to testing that values the tester as an integral part of the test process and shares the same values as the Agile Manifesto: Individuals and interactions over processes and tools. That’s how exploratory testing differs from ad hoc testing: in exploratory testing, you rely on your personal experience and design test cases in the testing process. An ad hoc testing can be done by any person without preparation.

User interface testing – By executing user interface tests, a QA specialist validates the properties and states of interface elements. Also, the QA team ensures that design elements in the interface match elements in the final layout.

As we can see, some tests should be performed manually. This especially relates to tests that focus on user interfaces and usability. Although we could automate basically everything, manual testing still provides an effective and quality check of bugs and improprieties.

The cases where manual testing has no comparison

UI Acceptance- Manual testing comes in handy when you test user interfaces, especially their visual aspects. Automated tests simply cannot detect colors of images or links, font sizes, gestures, and highlighting. Imagine that your application has a bug that causes a link to be so tiny that you can barely see it. Manual testers will immediately detect this bug, but automated tests are not able to notice the defect.

Initial development stage- Manual testing helps testers to detect bottlenecks during the initial development stage which results in less time and resources being spent on fixing bugs. Sometimes it’s not rational to invest money and human resources in automated testing during an unstable phase of a product’s development. However, in some approaches to software development, automated testing is a part of the process at any stage.

Short-term projects-Even though automated tests are aimed at saving time and resources, it takes time and resources to design and maintain them. In some cases, such as building a small promotional website, it can be much more efficient to rely on manual testing.

Non-automatable cases-Some tests cannot be automated; this especially concerns hardware-related tests. Writing scripts for automated checks of sensors, touchpads, and screens are almost impossible and rarely viable. Also, some data can be tested only manually. For example, you can automatically test if printer prints, but checking the quality and content of printed images is best done manually.

Conclusion

Manual Vs Automation Testing each have their strengths and weaknesses. What we want to stress is that no matter how great automated tests are, you cannot automate everything. Manual tests play an important role in software development and come in handy whenever you cannot automate the process.

NLOG with SQL Server and PostgreSQL in .Net Core

Monday, March 2nd, 2020

Here I am providing the steps to configure the Nlog for logging into the database in .net core.

  • Install NLog.Web.AspNetCore nuget package
  • Now, add a nlog.config file manually in the project and put all the configurations like file log path, database settings, etc. in this file. I have explained each in detail below.

We are going to use NLog with the database, so let’s create a table first in dB. The table structure is shown in the below screenshot.

Now, update your nlog.config file

<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    autoReload="true"
    throwConfigExceptions="true"
    internalLogLevel="info"
    internalLogFile="c:\temp\internal-nlog.txt">

<extensions>
  <add assembly="NLog.Web.AspNetCore"/>
</extensions>
<targets>
  <target name="database" xsi:type="Database" connectionString="" >
    <commandText>
      INSERT INTO "NLogs" (
      "Application", "Level", "Message", "Logger", "Callsite", "Exception", "Logged")
      VALUES ( @Application, @Level, @Message,
      @Logger, @Callsite, @Exception,@Logged);

    </commandText>

    <parameter name="@application" layout="AspNetCoreNlog" />
    <parameter name="@level" layout="${level}" />
    <parameter name="@message" layout="${message}" />

    <parameter name="@logger" layout="${logger}" />
    <parameter name="@callSite" layout="${callsite:filename=true}" />
    <parameter name="@exception" layout="${exception:tostring}" />
    <parameter name="@logged" layout="${date}" />
  </target>
</targets>

<rules>
  <logger name="*"  minlevel="Debug" maxlevel="Error" final="true" writeTo="database" />
</rules>
</nlog>

Let’s discuss the nlog.config file layout.

Top-level elements

The root element is nlog in nlog.config file. The use of an XML namespace is optional but enables Intellisense in Visual Studio. We can set the internal log file path to internalLogFile. We can check the working log status in this file. So, if nlog is not working, you can check this file to know the issue.

NLog config is case-insensitive when not using a namespace and is case-sensitive when using a namespace.

You can use the following elements as children to nlog. Targets and rules are required in any configuration and others are optional and can be useful in advanced scenarios.

targets — defines log targets/outputs

rules — defines log routing rules

extensions — loads NLog extensions from the *.dll file

include– includes external configuration file

variable — sets the value of a configuration variable

The simplest configuration consists of one target and one rule (logger) that routes messages to the target.

Targets

The targets section defines log Targets. Each target is represented by a target element. There are two attributes required for each target:

name — target name

type — target type — such as “File”, “Database”, “Mail”, “Cloud”. When using namespaces this attribute is named xsi:type.

To know more about targets click on the below link

https://github.com/nlog/nlog/wiki/Configuration-file#targets

Here our log target is the database. So, inside the targets, we have defined our target as a database.

<target name=”database” xsi:type=”Database” connectionString=”” >

In the target tag, we’ll define the database connection string.

Note:- The default db provider will be SQL server if you are using any other database you will need to set the dbProvider.

<commandText>
INSERT INTO “NLogs” (“Application”, “Level”, “Message”, “Logger”, “Callsite”, “Exception”, “Logged”) VALUES (@Application, @Level, @Message, @Logger, @Callsite, @Exception, @Logged);
</commandText>

The statement inside the commandText is the insert SQL statement for inserting the logs in NLog table.

Now, declare all the parameters that are going to be inserted in the NLog table. The parameter node will contain the property name and Layout.

<parameter name=”@application” layout=”AspNetCoreNlog” />
 <parameter name=”@level” layout=”${level}” />
 <parameter name=”@message” layout=”${message}” />
 <parameter name=”@logger” layout=”${logger}” />
 <parameter name=”@callSite” layout=”${callsite:filename=true}” />
 <parameter name=”@exception” layout=”${exception:tostring}” />
 <parameter name=”@logged” layout=”${date}” />

To know about the layout, please follow the below link

https://github.com/nlog/nlog/wiki/Configuration-file#layouts-and-layout-renderers

Rules

The rules section maps loggers to targets and log levels.

https://github.com/nlog/nlog/wiki/Configuration-file#rules

Now, in .net core application update the below line in Program.cs .

public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
           WebHost.CreateDefaultBuilder(args).UseNLog()
               .UseStartup<Startup>();

The Logging configuration specified in appsettings.json overrides any call to SetMinimumLevel. So either remove “Default”: or adjust it correctly to your needs.

{
“Logging”: {
“IncludeScopes”: false,
“LogLevel”: {
“Default”: “Trace”,
“Microsoft”: “Warning”,
“Microsoft.Hosting.Lifetime”: “Information”
}
},
“AllowedHosts”: “*”
}

Remember to also update any environment-specific configuration to avoid any surprises. Ex appsettings.Development.json

Write logs

Inject the ILogger in you controller:

using Microsoft.Extensions.Logging;
public class HomeController : Controller {
private readonly ILogger<HomeController> _logger;
public HomeController(ILogger<HomeController> logger)
{
_logger = logger;
_logger.LogDebug(1, “Log Debug”);
}
public IActionResult Index() {
_logger.LogInformation(“Hello, world!”);
return View();
}

Note: If you don’t see any logging in db, please check the file internallogfile (path set in the nlog.config file). You can check the issue with logging in this file.

To configure the NLog with Postgres, we just need to make a few changes.

Change the db configuration settings for the postgres in nlog.config file.

<target name=”database” xsi:type=”Database” dbProvider=”Npgsql.NpgsqlConnection, Npgsql” connectionString=”User ID=;Password=;Host=;port=;Database=;” >
<commandText>
INSERT INTO public.”NLogs” (“Application”, “Level”, “Message”, “Logger”, “Callsite”, “Exception”, “Logged”) VALUES (@Application, @Level, @Message, @Logger, @Callsite, @Exception,@Logged );
</commandText>

That’s it, rest things will be the same as the above (NLog with SQL server).

Azure Bastion: Secure way to RDP/SSH Azure Virtual Machines

Monday, March 2nd, 2020

Microsoft Azure has recently launched Azure Bastion; a managed PaaS service to securely connect to Azure Virtual Machines (VMs) directly through the Azure Portal without any client needed.

Generally, we connect to the remote machines by either RDP or SSH. Before Bastion, if we need to connect to a VM in Azure we either need to expose a public RDP/SSH port of the server(s) or we need to provision a separate jump box server with said ports exposed and then connect to the private machines via the jump box server.

Exposing RDP/SSH ports over the Internet is not desirable and considered as a security threat, and with Azure Bastion, we can connect to Azure VM(s) securely over SSL, directly in Azure Portal and without exposing any ports. This also enables clientless connectivity meaning no client tool like mstsc is needed. It just requires a supported browser to access the VM.

Key points

  • Azure Bastion is a fully managed PaaS service that provides secure and seamless RDP/SSH access to Azure VM(s)
  • No RDP/SSH ports need to be exposed publicly
  • No public IP is required for VM(s)
  • Access VM(s) directly from the Azure portal over SSL
  • Help to limit threats like port scanning and other malware
  • Makes it easy to manage Network Security Groups (NSGs)
  • It is basically a scale set under the hood, which can resize itself based on the number of connections to your network
  • Azure Bastion is provisioned within a Virtual Network (VNet) within a separate subnet. The name of the subnet must be AzureBastionSubnet
  • Once provisioned, access is there for all VMs in the VNet, across subnets
  • Get started within minutes

Getting Started

  • Select the VNet, in which you have the VM(s), which you want to connect. Create a subnet on which the bastion host will be deployed. Make sure that the range of networks is at least /27 or larger and the name of the subnet is AzureBastionSubnet.
  • Now go to the Azure portal and create a Bastion service and fill in the required details.
  • Once the Bastion is provisioned, just navigate to the VM, you want to RDP/SSH and click Connect. There you will see an option to connect using Bastion.
  • Just enter the username and password and Connect. You can also login using a username and SSH private key for Linux if it is configured.
  • This is it. When connected, the remote session will start in the browser window.

Limitations

The service is not available in all regions, and the Azure folks are working on adding it to all regions eventually. As of now, the file transfer service is not available but we hope this feature will get added in the future, however, text copy-paste is supported. Keep visiting the service documentation for more details and feature updates.

UI Android vs iOS UI

Friday, January 24th, 2020

User Interface (UI) as dynamic as it is, individually takes yet another turn in the diversity section when we come to Android vs IOS.

You must have heard sagas of the differences between the android and iOS users each pleading a case of how their operating system is better than the other. But what you may not know is that this isn’t new, it has been the case for ages now. And, on no account can you term it as superficial. Android users do have a very tough time adjusting to iOS and vice versa. The “why” to this problem has a lot of little aspects and one major aspect. The major one is the differences in the UI of the two. Think about it, for instance, a layman while comparing two devices with these two operating systems may ignore for once, the differences in the complex configurations behind the processors in the two, but what he will always keep in mind is “how does is screen look?” “which icon goes where?” “how do you navigate through different pages?” and all of these have only one thing in common- UI.

Thus, it becomes essential for us to understand the differences between the UI in the two operating systems so that if need be we can make an informed choice and in a more competent fashion.

Now that we have started, we need to know where all will we be able to spot these differences. The best answer to this is — “If you scrutinize the subtle, then everywhere.” These differences are present everywhere — in the navigation bars, toolbars, types of control, buttons, and whatnot.

Out of these hundreds our focus first, obviously goes to navigation. Android is based on the material design guidelines, which is something widely accepted and followed globally even google uses them while developing its own applications. iOS, on the other hand, is based on the human interface design. One of the most noticeable differences in navigation is how android uses a “universal navigation bar” present at the bottom of the screen but iOS uses a combination of gestures and the home button. It also presents itself with an inbuilt “back button” in almost every one of its apps to help with the simple retracing of steps. Now you may be able to see how even a simple action as “going back” becomes so different with a change of UI.

Similar to navigation is another aspect — Menu. In Android, they generally have it in the form of a sidebar where you just tap and pull and voilà — you will have five to six apps ready to access. iOS, on the contrary, prefers a tab bar, which is placed at the bottom of the screen. These tab bars though according to various consumer analysis reports are easier to use, provide a lesser array of apps to be at the user’s disposal at one point of time.

The search field too is not left behind in this gabble of differences. In fact, the amount of comfort drawn from a device has a huge dependence on the accessibility of the search field, and its placing and presentation in the two operating systems play a pivotal role in materializing the differences between the two. One of the most distinguishing in this arena is the placement. iOS demonstrates a certain amount of rigidity as the full search bar is placed at the top of the screen. Whereas Android provides its users with a little bit of flexibility on the matter. It gives the users an option to place the search bar on the top, which is majorly different from what was provided by iOS because this one only expands into a full search bar upon tapping the search icon. The second option enables the search bar to gain much-deserved mobility as Android presents the users with an option to access the search field in the form of a widget that can be placed according to the user’s whim.

Pages on the second or lower level of hierarchy use segmented control in iOS and a tab on the Android. Furthermore, all text tabs in Android are present in uppercase and in iOS as a title case. This coupled with a fact that Android UI comes with a “text-only” policy for these tabs, which allows no icons and texts to be present simultaneously on the tabs and that iOS has no such policy, gives another important point of distinction to the two operating systems.

Another fundamental difference between the UI of the two can be observed in the color and size of the apps provided, Android usually has a more multi-color approach, with icons which are big in size and have reasonable spacing in between, on the other hand, iOS prefers a black and white pallet with a more compressed outlook.

A large difference further exists in the form of buttons, dialogues, alerts, etc. But as we explore these and many more, we must also understand the fact that these are all very temporary. The general trend today shows enough cases that indicate that we are moving towards a more converging user interface present in Android and iOS. The addition of the “switch” option to Android from the exclusive domain of iOS being one of the many examples of the same.

So, after understanding the differences in the two UIs and analyzing the various trends associated to it, one may also draw a parallel conclusion that with the passage of time as the consumer becomes more knowledgeable and demands for more and more freedom in mobility, structure, and outlook, the products will begin to have more and more fluid user interfaces and thus skipping the boundaries drawn by the differences in the operating systems and ultimately being a junction of the two categories we see today!

API Testing and How to do it?

Thursday, January 23rd, 2020

Introduction

Before getting into what API testing is, it is essential to understand what an API is. An API (Application Programming Interface) indicates how two software programs should integrate with one another.

API (Application programming interfaces) testing is a kind of software testing that involves testing APIs directly and as part of integration testing and to determine if they meet the requirements of functionality, performance, security, and reliability. API testing is a form of Black Box testing and is conducted after the build is ready. The source code is not included here.

The Challenge

To test the APIs and the integrations, they enable a software system.

The solution

To perform API testing, a tool is required to structure and manage the test cases. Another requirement is full traceability of requirements and effective API documentation.

During API testing, certain bugs can be found. These bugs include:

  • Duplicate or missing functionality
  • Incompatibility of the error handling mechanism
  • Reliability issues
  • Security and performance issues
  • Improper messaging
  • Multi-threaded issues

The quality assurance team performs API testing. The testing is conducted after the build is ready. The source code will not be included here.

A request is sent to the API to analyze responses that include:

  • Accuracy of data
  • HTTP status code
  • Error codes of any errors that are returned by API
  • Results of non-functional tests like security and performance
  • Response time
  • Authorization checks

Use a test management tool that will help in API testing by letting you structure and categorize your test cases. The tool should also give you full requirements traceability along with high-level API documentation. During API testing, the following must be kept in mind:

  • The API must be tested to check what happens and what does not happen on a consistent basis.
  • Stress testing on the system must be performed through several API load tests.
  • The API must be tested for failures. Test the API consistently so that it fails consistently.
  • Group all the test cases by category.
  • Mention all the parameters that are selected in the test case.
  • Prioritize API function calls so that testing can be simplified and can be finished on time.
  • Make plans to perform call sequencing.
  • Create test cases for different and all API input combinations that are possible. This way, you can ensure that you get complete test coverage.
  • Reuse the test cases and also monitor the API when in production.
  • It depends on the manual and automated tests if you want better API testing outcomes.

API testing is a very important part of software quality assurance. With the right approach and the right tools, you can ensure it is carried out successfully. The more API testing is structured, the better will be the outcomes of the testing.

Key Insights into the Future of Software Testing — 2020 Vision

Thursday, January 23rd, 2020

With the growth of digital technology and the widespread use it has in our daily lives, the need for reliable and efficient software testing has also increased. Developers need to ensure product quality after an app design agency works on it and before it is rolled out into the market. As such, it is not an exaggeration to say that software testing determines the fate of a product.

Considering the huge role that software testing plays in the success of an app, it is important to know where the industry is headed to in the coming years. Such insights help us understand how better to improve the products that are put out most efficiently.

Before learning about future insights read another article about software testing from the link:- https://medium.com/@successivetech/getting-started-with-testing-react-component-e9e811856f3c

Below, we take a closer look at four main insights that are predicted to dominate the software testing industry in 2020:

Testing both the API layer and UI layer are equally important

Most professionals who are involved in software testing, such as developers, project managers, manual testers, and so on, test both the front and back-end of applications. This indicates that today, testing the API layer is equally important as testing the UI layer. Since testers are tasked with testing multiple layers of software, they must be equipped with the necessary tools so that they can test with ease. In the coming years, more testers will likely focus on both API and UPI layers.

Machine learning-enabled automated testing is the future

By 2020, the number of testers automating more than half of their API tests is expected to grow significantly. This means that automated testing will soon be the norm in the near future. Machine learning has already heavily impacted the way software is developed, and its impact on software testing is also expected to grow. For instance, machine learning can be used to optimize the test suite to search for excessive, or it can be used to predict the main test configurations based on previous checks.

Teams are working on shortening release cycles

Even though teams are not as agile as they wish to be, this trend is likely to change as they are continuously working on deploying more regularly. A huge number of software testers are expected to release either daily or weekly in the coming years, thus shortening their release cycles.

More focus on user experience

High-quality UX has grown to become one of the most important determinants of success for products in the world of software today. Regardless of whether the product is aimed at a simple user or for an experienced software developer, being user-friendly is a crucial key. This is exactly why testing user experience has become such a critical part of software testing, and the need for the best UI/UX design services is growing. This trend is expected to grow in the coming years.

Out-for-sure-cing! Outsource to Save Time & Resources

Thursday, January 23rd, 2020

Let’s go back to the old adage — ‘Alone we can do so little, together we can do so much.’ We could argue that maybe self-sufficiency is a more important thing to learn and one must try to hone his or her skills until overall proficiency is achieved. But it is no surprise that this is better said than done and it is no surprise that indeed, there is power in joining hands.

You cannot be the best at everything but if you do know others who are masters in their domains, collaborating with them can lead to a successful and invincible association. That is how educational institutes work. Instead of hiring one professor who can teach both science and math pretty well, they hire a different teacher for each subject; such that their mastery cannot be challenged and to ensure that students learn from the best.

In business, similarly, outsourcing is the way or agreement through which one company entrusts its own internal activities to an external vendor or company. This involves any functions that can be carried out from an offshore location. They can be operational or non-core functions like manufacturing, accounting, call-center support, etc. or business functions like inventory management, transaction and payroll processing.

The concept, though seemingly absurd, has gained popularity due to the wide array of advantages it poses.

1. Cost and time zone advantages

One of the biggest advantages of outsourcing is cost savings. Many times, it is not cost-effective to expand operations internally due to inefficient equipment or inappropriate location. It may be possible that your business has grown to such an extent that you require a bigger office. In such a situation, you could either outsource basic operations to reduce the need for space or expand or relocate your base to a different place. The latter can prove to be much more cost-efficient and less troublesome.

“If you deprive yourself of outsourcing and your competitors do not, you’re putting yourself out of business.” — Lee Kuan Yew

When outsourced, a job can be done in a satisfactory manner and at a much lower cost. A major reason for this is the difference in wages between western and many Asian countries. Outsourcing to India reduces costs by almost 60% due to lower labor operation costs and lower overhead costs. Another important aspect is round-the-clock efficiency due to different time zones across countries.

Suppose an American firm outsources to a Malaysian company. The firm manager might be done for the day but will wake the next morning with tasks completed by the Malaysian employees. This is how outsourcing keeps things running throughout the day.

2. Access to skilled resources and increased efficiency

When the functions of your back office are complex and difficult to achieve given the current size of your company, outsourcing can be a breath of fresh air since overhead costs pertaining to a particular back-office function can be extremely high. When you outsource your business needs, the partner brings to the table immense experience, tactful business practices, and expertise.

They can handle a complicated project with much more prowess and understanding of the subject area. Basically, outsourcing gives businesses the ability to develop new competencies and skill-sets that can be used as a competitive advantage. This boom in productivity and efficiency would make businesses more successful, more equipped to tackle challenges and helps them streamline cash flow.

“The important thing about outsourcing or global sourcing is that it becomes a very powerful tool to leverage talent, improve productivity and reduce work cycles.” — Azim Premji

3. Better services and focus on core areas

Outsourcing certain non-core business processes like administration and back-office operations, that tend to expand during rapid growth periods, helps you focus on other important aspects by saving time and energy. This is because the expansion might start to sabotage those core activities that form the foundation of your company.

“Do what you do best, and outsource the rest.” — Peter Drucker

Moreover, in case of certain cost-incurring operations that are going haywire or are poorly managed, outsourcing helps to overcome such difficulties by bringing better management skills to the table. It allows you to focalize your in-house resources on building the brand, providing higher value-added services, research and development.

In case a firm receives a contract that would multiply its purchasing volume by a number of times in a short span, it should outsource this function so that its personnel can concentrate on the contract itself. Outsourcing helps companies provide better and faster services in this way leading to high-quality deliverables and lesser time for products to reach the marketplace.

4. Save on Infrastructure and technology

Outsourcing eliminates the need for investments in technology, infrastructure, and people. These form a major section of the capital expenditure that is incurred in back end processes. This is because the outsourcing partner is given the responsibility of handling the business process and is hence, solely responsible for developing the required infrastructure as well.

If a business has outsourced its creative design department, it is not their concern if the latest software is being used or not or how many UX/UI designers are working on a particular project. Their only concern is to see if tasks are being completed on time and accurately. Everything else will be taken care of by the outsourcing partner. Similarly, if a tech company has outsourced its catering, it does not need to worry about whether the stove is working or not or if there is enough ice in the refrigerator. This will be handled by the caterers now since it falls under their domain.

5. Staffing Flexibility

Through outsourcing, you can pick the best people to deal with your core activities, manage your manpower and have flexibility in staffing. A large project might require expertise or skills that your internal staff does not possess. In such a case, it is a good option to bring in contractors who know the requisite workers or people with the required skill set. Your internal staff, in the meanwhile, can imbibe knowledge and skills by working with them to increase their proficiency.

“If you think it’s expensive to hire a professional, just wait until you hire an amateur.” — Red Adair

Moreover, certain functions in the company have seasonal or cyclical demands. Thus, external or additional resources can be employed when things are at a good pace and let go when not needed. This also helps save costs. As an example, an event management company might have a wedding department that is shorthanded for certain months of the year. Outsourcing a few of its responsibilities can help you with services during these few months at a fixed cost.

6. Continuity and Risk Management

Many times, due to one reason or another, the employee churn rate in some companies is quite high. This can cause instability and uncertainty. Outsourcing in such situations is a blessing since it helps maintain consistency and strike a balance because a substandard level of operation can jeopardize the overall functioning of the business.

As an example, if your account manager is on leave due to a family obligation for the next month and there is no one to take his place, it is wise to outsource this job since it will help manage the risk situation effectively for the time being. In this way, outsourcing helps your business sail through tough times.

Now, you know there really aren’t too many reasons against diving into this culture. Save time. Save money. Save energy. Increase your efficiency. Gain access to skilled resources. Cut down on your costs. Steer through sticky situations. Outsourcing has its set of disadvantages but as long as the advantages overpower them, it is a win-win. So, the next time you have a problem you think you cannot handle, outsource; finding it tough to keep the ball rolling, outsource; have too much on your plate, outsource…Getting the drift?

How To Choose The Right Outsourcing Partner

Thursday, January 23rd, 2020

Tech firms are increasingly relying on outsourcing, especially for software development to increase their productivity, reduce development time and tackle overall competition. And if all this can be achieved within the budget, it is the icing on the cake!

However, it is not as simple as it looks. There are a million other things that influence this outsourcing agreement, much like any other business strategy that is framed after due deliberation. For starters, what things should you keep in mind while choosing your outsourcing partner? This is not a frivolous decision but one that can greatly influence the firm’s future. So, sufficient time, energy and effort must be invested in the same to develop a fruitful association.

Why are you outsourcing in the first place?

This is the most important question to ponder upon since outsourcing is not a cure-all; it is only as efficient as the standard one sets. This is extremely crucial so as to set concrete goals. Something like ‘what is the current level of output or performance and what is desired?’ is a great thought to begin with. Hence, eliminate any vagueness or uncertainty in your overall expectations.

Evaluate your partner carefully

Joining hands with an outsourcing partner involves investment in both time and resources. You’ll spend energy to fill a team in on the working of your organization. But all this will go in vain if you end up concluding that they are lacking in skills and technical prowess. Similarly, you can find your ideal outsourced team but it won’t mean much unless it is able to stick around for a good number of months or years. Hence, don’t be reluctant and do ask hard questions to be able to choose an established outsourcing partner.

Choose the right size team

This might seem trivial but it plays a pivotal role in determining the strength of your association with the outsourced team. There is often a misconception that it is best to partner with the largest vendor but sometimes, this can have the opposite effect as well. For example — a large outsourcing provider might not be able to attend to each client with enough care; smaller clients might be neglected and made to associate with developers who are not as proficient. It is also likely to charge much more for its services on account of its brand name and good track record. Hence, a large vendor is apt only when it has to be assigned to a client that is large enough to command its attention.

Smaller partners are usually more flexible, have lower rates and attend to all clients with sufficient attention and effort. Their senior management is more involved in all the projects and this is a big boon. It is also an advantage that cannot be conferred in the case of large vendors.

Investigate

Bring out the Sherlock Holmes in you and carry out a background check. What projects has the outsourcing partner already worked on? What customers did it deal with? Ask for references to get firsthand information on what it’s like to work with that team. Is the outsourcing provider financially secure? Does it have sufficient infrastructure and technology to carry out the designated tasks? Know all this before bringing them on board.

Know the contract like the back of your hand

When partnering with an outsourcing provider, it is always a good idea to obtain legal consultation. In the case of software development, it is all the more crucial due to shared intellectual property that needs to be defined clearly. A non-disclosure agreement is also signed to prevent the outsourced team from leaking any sensitive or private information.

Communicate well

The entire work mechanism is based on a meshwork of efficient communication and collaboration. Hence, it is important to ask a few important questions that influence this. Where should the outsourced team be placed? Will communication be possible if it is an offshore arrangement? Do the qualities of a team in another continent outweigh the problems it poses due to being in a different time zone? Would it be easier to work with a nearshore team? All these points need to be taken into account for a successful partnership.

A simple six-fold strategy, it is a must to consider the aforesaid checkpoints so as to find your ideal outsourcing partner. As for a discussion about such trends in the business and technological world, you needn’t look for ideal partners. We are right here, feel free to reach out.
