What occurs during "acceptance testing"?

During acceptance testing, the primary focus is on assessing whether the developed system meets the user requirements outlined in the original specifications. The process involves stakeholders, including end-users, who evaluate the system to ensure that it functions as expected and fulfills the intended purpose. This stage is crucial for validating that all user needs and business requirements have been adequately addressed before the system moves to production.

Acceptance testing serves as a final verification step, aiming to establish whether the system is ready for deployment. It helps to confirm that the deployment will satisfy the users' expectations and requirements, ultimately minimizing the risk of defects or inadequacies after the system is launched.

In contrast, other aspects mentioned in the alternative options focus on different stages of testing or system evaluation, such as performance monitoring during launch or establishing baseline performance metrics, which are not the primary objectives during the acceptance phase.
