The Timeline Retrospective is a useful way to look back at key events over multiple sprints or months, identify pain points, and develop action plans. This retrospective is typically not used by a single team over a sprint. It can be used by multiple teams that have worked together on a product. It is particularly helpful when understanding cause/effect relationships over extended periods of time.
This Guide shows you how to run a timeline retrospective, a practice that is particularly useful for multi-team multi-sprint retrospectives. Running a timeline retrospective typically takes 90 minutes to four hours.
