User Acceptance Testing (UAT) is a critical phase in the software development life cycle. It is conducted after the completion of system testing and before the software is deployed to the production environment.
The purpose of UAT is to validate that the software meets the business requirements and is ready to be accepted by the end users. It focuses on testing the system from the users' perspective and ensuring that it functions as intended in their real-world scenarios.
During UAT, end users perform various test scenarios and provide feedback on any issues or potential improvements. This helps in identifying any remaining defects, usability problems, or gaps between the system and user expectations. It also ensures that the software is user-friendly, intuitive, and meets the desired quality standards.
Successful completion of UAT is a key milestone as it indicates that the software is ready for deployment and use in the production environment. It provides confidence to stakeholders that the software will perform as expected and deliver the intended business value.
