Best practices
- ✓Define the period before collecting cards.
- ✓Use specific events and approximate dates.
- ✓Invite people from each stage of the work.

- ✗Discussing every event equally instead of prioritizing patterns.
- ✗Confusing a column-based reflection with a project scheduling tool.
About this template
What is a Timeline retrospective?
A Timeline retrospective organizes reflection chronologically. Instead of starting with a judgment about what went well or badly, the team reconstructs the period together: what happened first, what changed in the middle, and how things finished. This helps people who worked on different parts of a project build a shared picture.
LetRetro's version uses Beginning, Middle, End, and Takeaways. The first three columns hold concrete events and observations; Takeaways captures lessons and proposed changes. The phases are relative to the sprint or project you choose, so the same format works for a two-week sprint or a longer milestone.
Use Timeline after a release, a handoff-heavy sprint, or a project with changing requirements. Ask participants to add dates when useful, distinguish observed events from interpretations, and finish with a small number of owned actions. This is a column-based retrospective rather than a dated project-management timeline.
