After you complete testing in a Test environment, it is common to perform User Acceptance Testing (UAT) in a designated UAT environment, which could be a pre-production environment. UAT ensures that users will be able to successfully complete work and meet business objectives.

The team performs UAT on the microjourney incrementally throughout the sprints. Make a provision for final end-to-end and UAT defect fixes in your last sprint. This is sometimes referred to as "sprint Z" or a "hardening" sprint. After all UAT tests are completed without issues, sign-off on UAT test cases.
