What is the meaning of the term "user acceptance testing"?

User acceptance testing (UAT) refers specifically to the process where end-users assess the system to determine if it meets their needs and requirements prior to its full deployment. This stage is crucial because it validates that the software works in real-world scenarios and satisfies the intended user functionality. During UAT, feedback from users plays a vital role in identifying any issues or necessary adjustments, ensuring that the system is user-friendly and effective. This direct involvement of end-users helps to ensure that any features built into the system align with user expectations and operational workflows.

In contrast, other options focus on different aspects of the software development lifecycle? Developers conducting tests primarily focus on functionality and coding issues, while bug fixing is more about technical errors rather than user experience. Evaluations by marketing teams typically address marketability and user appeal rather than hands-on testing to verify the system's operational capacity and user satisfaction. Thus, B is the most accurate representation of user acceptance testing.
