What occurs during a User Acceptance Test (UAT)?

During a User Acceptance Test (UAT), end-users validate that the solution meets their expectations by engaging with the system in a way that mimics how they would use it in real-world scenarios. This phase is crucial because it allows users to assess the software for usability, functionality, and overall satisfaction before it goes live. Their feedback is vital, as it helps identify any discrepancies between the system's capabilities and the users' requirements or expectations.

UAT is a user-centric evaluation that focuses on the final product, ensuring it is ready for deployment. This testing phase is typically the last step before a project goes into production and emphasizes how well the solution serves the end users, incorporating their insights to confirm that the requirements have been satisfactorily met.

In contrast, the other options refer to different activities that are not the primary focus during UAT. For example, internal testing by the development team typically occurs earlier in the software development life cycle to ensure technical functionality and quality. A formal review of project documentation is more aligned with project management processes rather than the acceptance testing performed by users. Technical training for project stakeholders is essential to ensure users understand how to use the system, but it is separate from the actual validation of the solution that occurs during UAT.
