More mistakes(2)
Handle with care. Do not confuse UAT with QA or testing. UAT is specifically end-user testing, not developer or QA testing. Also, do not use UAT as a verb casually; it requires proper context.
- ✕We will UAT the entire system next sprint.✓We will enter UAT phase next sprint.
While UAT can be used as a verb, it is more natural to say 'enter UAT phase' or 'conduct UAT' rather than simply 'UAT' as a bare verb.
- ✕UAT is the same as QA testing.✓UAT is different from QA testing; QA focuses on bugs, while UAT validates business requirements.
These are distinct testing phases with different goals and participants.
