Kanban vs Scrum

A comparison of two agile approaches: Scrum works in fixed-length Sprints with set accountabilities, and Kanban manages a continuous flow of work with limits on work in progress.

The Kanban Method manages a continuous flow of work on a visible board and limits how much is in progress at once, pulling new work in only when there's room. Many teams mix parts of both.

Pick Scrum if

  • The work can be planned in chunks of a few weeks, and a fixed goal per Sprint helps the team focus.
  • You want a set rhythm of planning, review and retrospective built in.
  • One person can own the order of the work as Product Owner.

Pick Kanban if

  • Work arrives unpredictably, like support requests or household jobs, and can't wait for the next Sprint.
  • You'd rather improve the way the team already works step by step than adopt a new set of events.
  • The main problem is too many things started and too few finished.

Short version to try today (Buhata's own example). A household with a steady stream of small jobs could try a three-column kanban board with a limit of two in progress. A family planning a move by a fixed date could try one-week Sprints with a single goal each.

Good to Know

Plenty of teams mix the two. Scrum.org's "Kanban primer for Scrum Teams" describes Scrum Teams adding Kanban's flow measures, such as cycle time and cumulative flow diagrams, to see how work moves through a Sprint. Scrum.org also notes that velocity and story points come from other agile methods and aren't part of the Scrum framework, so a Scrum team can work well without them. Check the Scrum Guide at scrumguides.org and the Kanban Guide at kanban.university for the current rules of each.

FAQ

What's the main difference between Kanban and Scrum?

Scrum works in fixed-length Sprints of one month or less with a set team and events. Kanban manages a continuous flow of work and limits how much is in progress, with no fixed iterations or required roles.

Is Kanban better than Scrum?

Neither is better for every team. Kanban suits work that arrives unpredictably, and Scrum suits work that can be planned toward a goal every few weeks.

Can you use Kanban and Scrum together?

Yes. Scrum.org describes Scrum Teams using Kanban practices such as cycle time and cumulative flow diagrams inside their Sprints to see how work moves.

Tasks, Calendar and Rhythms (Team X)

For Scrum, put Sprint events on the Calendar in a Team Space and run the Daily Scrum in Rhythms with the Team X add-on; for Kanban, keep a steady list in Tasks and finish one before starting the next.
