Pick one:
- Yes, it is ok, the team needs to be managed by the Scrum Master who decides when to adjust.
- Yes, if the Product Owner approves
- No, use the time box to help detect when things are not well understood and where clarity is needed. Time boxes bring rhythm
- Sometimes, if the Product Owner and Scrum Master agree
A time box is a common practice underlying most agile processes especially, Scrum. Time boxing is a the closest thing in agile or scrum that we have to something that is clearly a best practice. Most managers or early adopters of Scrum wonder what they do to create a sense of urgency and the answer is simple “Time Box”.
In Scrum we have 6 formal timeboxes.
- Release Planning
- Sprint Planning
- Sprint
- Daily Standup
- Sprint Review
- Sprint Retrospective
Time boxes are a key element in Scrum. They form the a bases for how we manage the team’s energy. The general rule in using time boxes is to not adjust the time once you have set it. When the clock runs out the bell “dings” and things change.
#1 mistake those new to Scrum make is to adjust the sprint length to give the team more time to complete their work. Basic Scrum training should cover and provide an in depth explanation of why not to adjust the time box.

Other time boxes can be applied and should be. The purpose of the time box is to cause movement and to set an expectation that we will limit the time and energy spent in any one direction. Generally people will fall prey to taking on too much work or big amorphous work that has no discernibly edges or clarity. Our understanding is similarly fuzzy and vague.
We can use a time box for many things including as a guide line in how we break work down into tasks or execution. Sometimes people use time boxing as a way to avoid gold platting or excessive polishing of an item or thing.
Time box is a critical practice in agile / scrum and should be applied with care. Arbitrary time boxing can drive motivation down and should not be used as a tool to create a frenetic pace or fearful environment. Time boxing is an important tool for any good scrum master or facilitator.
