What is the maximum timebox for a sprint planning event?

The maximum timebox for a sprint planning event is based on the length of the sprint, specifically one hour for every week of the sprint duration. This guideline is designed to ensure that the team has enough time to effectively plan and prepare for the work ahead without overwhelming them with excessive duration.

For example, if the sprint is two weeks long, the planning event would ideally be timeboxed to two hours. This structure facilitates focused discussions on the sprint goal, selection of backlog items, and how the team plans to execute the work, keeping the event concise and productive.

This timeboxing helps in creating a balance between preparing adequately and avoiding prolonged meetings that could lead to diminishing returns in terms of productivity and engagement. As sprints can vary in length, this rule adapts accordingly, providing flexibility while maintaining efficiency.
