What common challenge may arise during user acceptance testing?

During user acceptance testing (UAT), it is common for users to face time constraints or limited resources that prevent them from conducting a thorough evaluation of the system. UAT is critical as it involves actual users testing the system to ensure it meets their needs and requirements before going live.

When users have insufficient time, they may have to rush through the testing process, potentially leading to a scenario where critical issues are overlooked. Limited resources, whether in terms of personnel or tools, can also hinder the ability to test all possible scenarios effectively, resulting in a lack of confidence in the system’s performance once it is deployed. This can result in serious challenges post-implementation if significant bugs or usability issues are discovered after the system goes live, which could have been caught during a more thorough UAT process.

Other challenges, such as inadequate test case coverage, unavailability of test data, or lack of stakeholder engagement, can also impact the effectiveness of UAT, but they do not capture the essence of the widespread issue of users being unable to allocate enough time or resources for testing.
