User Acceptance Testing (UAT) is a crucial phase in the software development process where actual users test the software to ensure it meets their needs and requirements. This testing occurs after the software has been developed and is typically the final step before it goes live. Users evaluate the software's functionality, usability, and overall performance, providing feedback to the development team. The primary goal of UAT is to identify any issues or bugs that may not have been caught during earlier testing phases. By involving real users, organizations can ensure that the software is user-friendly and aligns with business objectives, ultimately leading to a successful product launch.
