What common challenge may arise during user acceptance testing?

User acceptance testing (UAT) is crucial as it determines whether the system meets the needs and expectations of end users. One common challenge that arises during UAT is that users may lack sufficient time or resources to conduct a thorough evaluation of the system. This situation can stem from several factors, such as conflicting work responsibilities, tight project deadlines, or insufficient allocation of resources for testing.

When users are unable to dedicate adequate time to engage with the system, it can lead to a superficial testing effort rather than a comprehensive assessment. This can result in critical defects going unnoticed, potentially leading to dissatisfaction with the system post-launch, because users have not identified key issues that could have been addressed before the system went live.

The importance of thoroughly engaging users in UAT cannot be overstated, as it ensures that the final product aligns with their requirements and expectations, ultimately impacting user adoption and the success of the project.
