What It Means
Scrum is a lightweight framework for teams working on complex problems, defined by Ken Schwaber and Jeff Sutherland in the Scrum Guide, most recently revised in November 2020. A small Scrum TeamScrum teamThe small, self-managing group that does the work in Scrum: one Product Owner, one Scrum Master and the Developers, typically 10 or fewer people. See more works in Sprints, fixed stretches of one month or less, and each Sprint aims to produce a useful piece of finished work. The team plans at the start of each Sprint, checks progress daily, shows the result at the end and looks at how it worked before the next Sprint begins.

Tap an event, or use Next, to see what happens at each point in a Sprint.
Sprint Planning
Opens the Sprint. The whole team agrees why the Sprint is worth doing, what can be finished and how. The Scrum Guide caps it at 8 hours for a one-month Sprint.
Daily Scrum
A 15-minute event for the Developers, every working day, to check progress toward the Sprint Goal and adjust the plan.
Sprint Review
Near the end, the team shows what it finished to the people with a stake in it, and together they decide what comes next.
Sprint Retrospective
The last event. The team looks at how the Sprint went and picks ways to work better in the next one, which starts right after.
Event of 4. All four sit inside the Sprint.
How People Say It
- "We run two-week sprints."
- "Let's take that to the retro."
- "That's for the product owner to decide."

How a team runs Scrum
- The Product Owner keeps an ordered list of everything the product might need.
- At Sprint Planning, the team agrees a Sprint Goal and picks the work to reach it.
- The Developers meet for 15 minutes each day to check progress and adjust.
- At the end, the team shows the finished work to the people it's for.
- In the retrospectiveSprint retrospectiveThe last Scrum event of each Sprint, where the Scrum Team looks at how it worked and picks the changes most likely to make it more effective. See more, the team decides what to change next time.
- The next Sprint starts right away.
Short version to try today (Buhata's own example). A family planning a move could run one-week Sprints: Sunday evening, agree one goal for the week ("kitchen and garage packed"), check in for a few minutes each morning, and on Saturday look at what got done and what to change.
Where It Comes From
Ken Schwaber and Jeff Sutherland created Scrum and wrote the Scrum Guide, which they revise together; scrumguides.org lists each edition, and the November 2020 edition is the current one. Both men were among the seventeen who signed the Agile ManifestoAgileA way of working, set out in the 2001 Agile Manifesto, that delivers in small pieces, gets feedback early and adjusts the plan as it learns. See more in 2001.
Good to Know
The 2020 edition changed some wording that older books and courses still use. It speaks of accountabilities rather than roles, so the Scrum Master, the Product Owner and the Developers are sets of duties inside one team rather than job titles, according to Scrum.org. Its name for the old "Development Team" is simply Developers. When a coworker quotes a rule, check it against the current guide at scrumguides.org, which is free to read.
FAQ
How long is a Sprint in Scrum?
One month or less, and fixed for the team. Many teams pick one or two weeks, and a new Sprint starts as soon as the previous one ends.
What are the three accountabilities in Scrum?
The Product Owner, the Scrum Master and the Developers. The 2020 Scrum Guide calls them accountabilities rather than roles, and all three belong to one Scrum Team.
Is Scrum the same as agile?
Scrum is one framework for working in an agile way. Agile is the broader set of values from the 2001 Agile Manifesto, and Kanban is another popular way to apply them.
