The primary objective of user acceptance testing (UAT) is to determine whether a software solution meets the needs and requirements of its intended users before going live. UAT involves end-users testing the application in real-world scenarios to identify any issues or discrepancies. This process is crucial for validating that the software functions as expected and aligns with user expectations. Successful UAT minimizes the risk of problems in production and enhances user satisfaction, ensuring the solution is ready for deployment.
