An issue is reported during User Acceptance Testing (UAT).

Assume it is a legitimate defect and assign any identified issue directly to the development team so they can fix and deploy the solution.

Prioritize the issue based solely on its impact on project timelines, fixing any issue that is easy to fix and deferring any deep investigation into its root cause.

Conduct root cause analysis for the issue to determine if it's a legitimate defect, a user training gap, or a new feature request, then route it to the appropriate team.
