UAT vs QA: what are their differences?

What is UAT?

UAT is an abbreviation of User Acceptance Testing. It is a type of testing conducted by the end users of the software, who are typically not familiar with the specific logic of the software but are familiar with the business processes. UAT testing is aimed at ensuring that the end users can perform the functions intended to replace/enhance the application.

In simple terms, UAT testing is performed to ensure that the end users can follow the updated workflow and complete their daily tasks using the new application, which may include underlying database tables replacing a spreadsheet system, for example.

How is UAT testing conducted?

To perform a UAT, you can follow these 6 steps:

1. Business requirement analysis: One of the most important activities in UAT is to identify and develop the testing approach.

2. Creating a UAT plan: The UAT testing plan outlines the strategies that will be used to validate and ensure that the application meets its business requirements.

3. Identifying test scenarios and test cases: Test scenarios related to high-level business processes are identified, and test cases with clear testing steps are created.

4. Preparing test data: It is preferable to use real-time data for UAT. Data should be encrypted for privacy and security reasons.

5. Running and documenting results: Execute the test cases and report any errors encountered. After fixing the errors, retest the application.

6. Confirming business objectives are met: After UAT testing, the business analyst or UAT tester needs to send a sign-off email. Once signed, the product is ready for production use.

What is QA?

QA stands for Quality Assurance. Its purpose is to ensure that the entire development lifecycle process adheres to established standards, thus ensuring the quality of the process itself.

For example, in the context of waterfall development, QA activities mainly involve auditing the processes and artifacts related to requirements, design, coding, testing and review to ensure that the implementation follows the organization's prescribed processes. Any deviation from the standard process is marked as a non-conformance and must be rectified within a specified timeframe, similar to how a traffic policeman issues a ticket to a driver who violates traffic rules. Through QA audits and tracking of non-conformances, the desired processes and specifications of the company can be effectively implemented and enforced.

UAT vs QA: what are their differences?

Quality assurance testing and user acceptance testing are both extremely important components of a software project. They both have different motivations and goals, but ultimately, they both work to ensure that the software is free of bugs.

Here, we have created a table detailing more of their differences:

Wrapping up

UAT vs QA, what are their differences? We can see that the main difference between the two is that quality assurance ensures that the software is bug-free, while user acceptance testing ensures that the software provides users with the experience and usability they are looking for.
