Blend on purpose.
Scrumban, a term coined by Corey Ladas, combines Scrum's rhythm with Kanban's flow. It works when you choose each piece deliberately.
Keep from Scrum
Rhythm
A sprint goal, the review with stakeholders, and the retrospective.
Add from Kanban
Flow
WIP limits, flow metrics, pulling work only when there's capacity.
Drop deliberately
What Doesn't Help
Maybe story points, or a fixed sprint commitment. Decide as a team.
