What is the maximum time-box duration for a Sprint Planning meeting for a one-month Sprint?

The maximum time-box duration for a Sprint Planning meeting for a one-month Sprint is 8 hours. This duration is established in the Scrum Guide, where it specifies that Sprint Planning should be time-boxed to a maximum of 8 hours for a one-month Sprint. This meeting is crucial as it sets the foundation for what the team will work on during the Sprint, allowing for the discussion of the Sprint Goal and the selection of Product Backlog items to be pulled into the Sprint. The time allocated ensures that all necessary discussions can occur to enhance shared understanding and commitment among team members regarding the upcoming work. Properly adhering to this time frame promotes effective planning without the meeting dragging on unnecessarily, which can reduce productivity and focus.
