Importance of QA in the SDLC

It is not about coding, but everything should work fine, look good, and satisfy the user. That is the role of Quality Assurance. QA checks whether the software is free from bugs, works efficiently, and meets the expectation of the user. Let us see how QA fits into SDLC in simpler words.

The SDLC is a step-by-step process for creating software, like a recipe, that helps turn ideas into fully working apps, websites, or programs by following each stage carefully

The Steps of the SDLC and QA's Role:

1. Planning:

This is the brainstorming stage. Teams decide:

What the software should do? Who will use it?What features are needed?

• QA's role:

QA helps review the plans to ensure they are clear and realistic. They may question, "Will this feature work for all users?" or "What if the user enters something wrong?" This can avoid problems later.

 

2. Designing:

Now it's time to make a blueprint. This includes:

How the software will look, the user interface.

How it will work behind the scenes.

• QA's role:

QA checks the design to ensure it is in line with the plan. For instance, if a login feature was planned, does the design show a clear and easy-to-use login screen?

 

3. Development:

This is when developers write the code and build the software.

QA starts testing small pieces of the software as they're built. They check if features work correctly and suggest fixes if something isn't right.

 

4. Testing:

The final step is a critical one to QA. Every functionality of the software is tried out to verify it works as designed.

QA examines:

• Functionality: Do buttons, forms, and features actually work?
• Performance: Does it run fast or handle many users?
• Compatibility: Does it function on different devices, browsers, or operating systems?
• Security: Is your user data safe and protected? QA acts more like a detective, finding out and fixing errors before the customer does.

5. Deployment:

This can go live and be used for real users.

Role of QA in launch:

QA also is sure that the launch would go smooth. They test the final set up at different levels before giving up and confirm that all things work perfectly in the live environment.

6. Maintenance:

Updates, bug fixes, and improvements are typical after a launch.

Testing the updates from time to time ensures that these don't crash the software. The QA checks for user responses for new problems arising and finds the solution to the same.

Helps in resolving problems early saves a lot of time and money

Makes Users Happy: Through Quality assurance, users find the product easily usable without errors. User data is saved with security testing, and his/her personal data will not go wrong.

This makes a tested product look like a quality product that has been worked upon by the company.

Quality Assurance is an essential step in SDLC. It ensures that software does the job expected, looks fantastic, and leaves the users happy. Without QA, apps may crash, take long to load, or irritate users.Quality Assurance, therefore, turns a good idea into a great product!
