What is the difference between Scrum and Kanban?

 Scrum and Kanban are both popular frameworks under the Agile umbrella, but they differ in how they structure work, roles, and processes.

Aspect	Scrum	Kanban
Type	A prescriptive Agile framework	A flexible workflow management method
Work Structure	Time-boxed Sprints (usually 2–4 weeks)	Continuous flow – work is pulled as capacity allows
Roles	Defined roles: Scrum Master, Product Owner, Dev Team	No required roles, but teams often define their own
Planning	Sprint Planning, Backlog Grooming, Reviews	No formal planning events required
Work Limitation	Sprint backlog limits work during a sprint	Uses WIP limits (Work In Progress limits)
Meetings	Daily Scrum, Sprint Review, Sprint Retrospective	Daily stand-ups (optional), and flow reviews
Metrics	Velocity, Burndown chart	Lead time, Cycle time, Cumulative flow diagram
Best For	Teams working in iterations, with evolving requirements	Teams needing flexibility and continuous delivery
Change During Cycle	Not allowed during a sprint	Allowed anytime – very adaptive
Delivery	At the end of the sprint	Delivered as soon as it's ready

🎯 Summary

• Scrum is structured, ideal for teams that benefit from a regular cadence and clear roles.

• Kanban is lightweight and more flexible, great for teams needing continuous delivery and fewer constraints.

🧠 Think of Scrum as working in "sprints," while Kanban is like a "relay race" – keep things flowing.
