Project Postmortems for UX Teams: Learning from Success and Failure

Postmortems are a structured analysis of completed projects that help teams understand what worked, what didn't, and how to improve. Success often provides more valuable insights than failure, yet many teams neglect to conduct postmortems for successful projects. This oversight limits opportunities for replicating effective strategies and learning from both outcomes.

Timing is crucial for effective postmortems. They should be held after sufficient data is available for projects with measurable outcomes, while projects without clear metrics should be reviewed within two weeks of completion. Additionally, postmortems must include clear success criteria, foster psychological safety to encourage honest feedback, and produce actionable deliverables that lead to systemic changes.
