In which phase of the SDLC is User Acceptance Testing (UA

User Acceptance Testing (UAT) is conducted during the Testing phase to ensure the software meets user requirements. 1. Validation by End-Users: Performed by stakeholders or end-users, UAT determines if the software behaves as expected in real-world scenarios. 2. Criteria: UAT focuses on functionality, usability, and adherence to business objectives. 3. Sign-Off: Successful UAT is often the final step before deployment, as it provides a formal approval from users. 4. Example: Testing a banking application to verify transaction accuracy under various conditions. UAT bridges the gap between technical correctness and user satisfaction, ensuring the software is ready for production. Why Other Options Are Incorrect: • A) Coding: Involves implementing design specifications and is not focused on user validation. • B) Requirement Analysis: Gathers requirements but does not involve software testing. • C) Deployment: Releases the software to production environments after UAT is completed. • E) Post-Production Maintenance: Focuses on resolving issues after deployment, unrelated to pre-deployment testing.
