Scrum vs. Kanban: Key Differences

AspectScrumKanban
StructureFixed-length sprints (1-4 weeks)Continuous flow (no sprints)
RolesProduct Owner, Scrum Master, Dev TeamNo fixed roles (flexible teams)
CommitmentSprint backlog (fixed scope)Work pulled as capacity allows

MetricsVelocity (story points/sprint)Cycle time, lead time, WIP limits

When to Use Scrum?

✅ Complex projects needing structured delivery (e.g., new SaaS product)
✅ Teams that benefit from regular feedback (sprint reviews)
✅ Clients who want predictable milestones

Example:
A startup building an MVP in 2-week sprints with prioritized user stories.


When to Use Kanban?

✅ Maintenance work (e.g., bug fixes, support tickets)
✅ Teams with unpredictable workloads (e.g., DevOps, marketing)
✅ Process optimization (visual bottlenecks via WIP limits)

Example:
An IT team handling incoming service requests with a “To Do → In Progress → Done” board.


Hybrid Approach: Scrumban

Combine the best of both:

  • Use Kanban’s flexibility with Scrum’s retrospectives.
  • Ideal for teams transitioning from Scrum to Kanban.

Visual Comparison

Scrum Board:

Sprint Backlog → [Task 1][Task 2][Task 3] → Sprint Review  

Kanban Board:

Backlog → Ready → Developing → Testing → Done  
           (WIP Limit: 3)  

Which Should You Choose?

  • Scrum if you need structure and predictability.
  • Kanban if you prioritize flexibility and continuous delivery.

🔥 Pro Tip: Start with Scrum for new projects, then evolve to Kanban for ongoing work.
