The Difference between Scrum and Kanban
Now, when you are one step closer to understanding what both methods are about, let’s have a more detailed look at the differences. Both methods may look very similar, but there have some major differences indeed. Let’s discover more in the following table.
|Creation||Invented as a simple scheduling system by Taiichi Ohno. Later, developed as the Kanban method by David Anderson and applied for knowledge work.||Started by Hirotaka Takeuchi and Ikujiro Nonaka as a term in the context of product development. Later developed by different software developers as a framework.|
|Intervals||Kanban has no time restrictions.||Scrum is time-boxed. The work needs to be completed in a predefined period of time (sprint).|
|Planning||Planning is optional.||The work is planned and divided into a set of smaller tasks.|
|Roles||Kanban doesn’t prescribe roles, while it respects the existing roles in a team.||In Scrum, everyone has a role (Scrum master/Product owner/Scrum team).|
|Commitment||Commitment is agreed based on capacity and it is an ongoing process.||In Scrum, the team commits to a certain amount of work.|
|Charts/Metrics||Lead time and Cycle time. Kanban prefers Cumulative Flow Diagrams, Cycle time histograms and so on. They offer a detailed overview of the ongoing processes.||Velocity is the key metric in Scrum. The Burndown chart is a must and illustrates how much work remains to be completed in a project.|
|Boards||The board remains continuous||The board is reset after each sprint|
|WIP Limits||Per workflow stage (per column)||Limits are not prescribed|
|Flexibility||Tasks can be added at any time depending on the capacity of the team||Tasks cannot be added|
|Prioritizing||Prioritizing is optional and it depends on common team agreement. It is not fixed.||Planned work should be prioritized in advance. Priorities can be changed if it is urgent.|
