What Is Sprint Planning Timebox?A timebox is a fixed period of time when a person or a team works towards an agreed goal. Agile project management uses timeboxing to keep work moving fast and on schedule. It is also a critical component of Scrum. A sprint planning timebox is the allocated time set aside to plan an upcoming spring, including story points, team capacity, risk and impediments, and more. Show Timeboxing was first referenced towards the end of the 1980s in the context of “Rapid Iterative Production Prototyping” techniques and explained in more detail in James Martin’s “Rapid Application Development” book published in 1991. Timeboxing is allotting a fixed, maximum unit of time for an activity. That unit of time is called a time box. The goal of timeboxing is to define and limit the amount of time dedicated to an activity. Timeboxing is a common feature of many project management methodologies because timeboxing keeps teams focused on accomplishing the task at hand by providing a clear definition of done. Five Scrum EventsIn Scrum, timeboxing is a critical component of all five events. Some Scrum teams also use timeboxing during a Sprint to concretely define open-ended tasks. In our other articles, we have discussed 3 Roles and 3 Artifacts in Scrum. There are five events in Agile Scrum Framework. In this article, we are going to discuss 5 events in the Scrum Framework and all these five events in Scrum are timeboxed. Five Scrum events
How Scrum Events are Timeboxed? Figures and PercentagesThe prescribed time-boxes are based on a sprint of 1 month. For shorter Sprints, the event is generally shorter. The time-boxes are:
If we also consider the on-going activity of refining the Product Backlog requires on average 10% of the capacity of the Development Team according to the Scrum Guide: For a full-time developer in a 4-week Sprint, the Scrum events take at most 22.5% of the time:
Here are the percentage for each of the 5 events in Scrum as shown in the Pie Chart below: Time boxed scrum events chartSummaryScrum uses time-boxed events, such that every event has a maximum duration. This ensures an appropriate amount of time is consumed in the events prescribed without waste in the Sprint process. Prescribed events are used in Scrum to create regularity and to avoid the need for other events not defined in Scrum. In addition to the Sprint itself, which is a container for all other 4 scrum prescribed events, each event has a defined goal to provide the opportunity to inspect and adapt various things for achieving the corresponding goal.
How long does a sprint planning meeting take?Sprint planning should be constrained no more than two hours for each week of the sprint. So, for example, the sprint planning meeting for a two-week sprint would be no longer than four hours.
What is the max timebox duration for sprint planning meeting?Sprint planning is limited to a maximum of eight hours. The general rule of thumb is to allow two hours of sprint planning for every one week of sprint length. That means teams should timebox sprint planning to four hours for a two-week sprint and eight hours for a one-month sprint.
At what time sprint planning is done?Sprint planning occurs on the first day of a new sprint. The event should occur after the sprint review and retrospective from the previous sprint so that any output from those discussions can be considered when planning for the new sprint. It does not have to occur immediately after those other two events.
