Deciding to Re-point a User Story
- The purpose of story point estimation is to reach a shared understanding of the story and provide an indication to the Product Owner of the level of effort required to deliver it, relative to other stories on the backlog
- A practice of re-pointing stories can encourage the type of "analysis paralysis" that a team experiences when it tries to provide precise hour estimates for a story or use case.
- It's expected that some story point values will be too high and some will be too low, that actual effort will vary from estimates. Story points on completed work provided an average value of historical velocity that is useful for forecasting team capacity.
