Key Phases of UAT

User acceptance testing (UAT) involves distinct phases, each crucial for successful software implementation. Let's break down the key stages:

Plan and Prepare

Before diving into testing, lay the groundwork. This involves meticulous planning, including creating comprehensive test plans and selecting the right testers. These testers should represent your target audience and have a good understanding of the software's intended use. A detailed UAT test plan should outline the scope, approach, deliverables, schedule, and importantly, the exit criteria. Testing typically happens in a separate testing environment, mirroring the production environment as closely as possible. This ensures that the software is tested under realistic conditions. 

Design Tests

With your plan in place, the next step is designing the tests themselves. This involves creating realistic test scenarios that mirror how users will interact with the software. Think about the typical tasks users will perform and the different ways they might use the software. The business analyst plays a key role here, preparing detailed test cases that are reviewed and approved by the business owner. These test cases should reflect real-world use, ensuring that the software is thoroughly tested under practical conditions. 

Execute and Collect Feedback

Now it's time to put the software to the test. During this phase, your selected users will test the software and provide feedback. They'll follow the test cases you've designed, documenting any bugs, issues, or areas for improvement. Encourage testers to be as specific as possible in their feedback, noting the steps they took, the expected outcome, and the actual result. Remember, the goal is to identify any issues before the software goes live. Testing should follow actual business procedures, using real data whenever possible.

Evaluate and Resolve Issues

The final phase of UAT involves evaluating the feedback collected and resolving any identified issues. Developers work to fix bugs and make necessary improvements, and then users retest the software to confirm that the fixes are effective. This iterative process continues until the software meets the pre-defined acceptance criteria. Clear documentation is essential during this phase. Logging bugs in a system like Jira and linking them to the relevant test case and business requirement helps maintain clarity, streamline communication, and minimize disagreements.

Who Uses UAT?

User Acceptance Testing isn't confined to a single team. It involves a diverse group of people, each with a unique perspective and set of responsibilities. Let's take a closer look at the key players involved in a typical UAT process.
