Scrum and Kanban solve different problems. The choice depends on work type, team maturity, and predictability requirements. Here is the practical guide.
Core Difference
Scrum structures work into fixed-length sprints with committed scope. Kanban visualises continuous flow and limits work in progress without cadenced commitments.
Framework Comparison
| Dimension | Scrum | Kanban |
|---|---|---|
| Cadence | Fixed sprints (1–4 weeks) | Continuous flow |
| Commitments | Sprint goal + backlog items | WIP limits only |
| Roles defined | Yes (SM, PO, Dev Team) | No prescribed roles |
| Change mid-cycle | Discouraged in sprint | Acceptable |
| Best for | Feature development, new products | Support, maintenance, ops |
| Key metric | Velocity, burndown | Cycle time, throughput |
When Scrum Is Right
- Building a new product or feature set with evolving requirements
- Team benefits from regular planning and review cycles
- Stakeholders want predictable release cadence
- Work decomposes into stories that fit within a sprint
When Kanban Is Right
- Team handles incoming requests of unpredictable size (support, bug fixes, ops)
- Work items arrive continuously and cannot wait for sprint planning
- You want to expose and reduce bottlenecks in an existing process
Scrumban: When Neither Fits Cleanly
Scrumban combines Scrum structure with Kanban flow. Teams use a backlog and WIP limits but without hard sprint commitments. Replenishment happens when the WIP queue drops below a trigger level rather than on a fixed cadence. Works well for teams where priorities shift too rapidly for sprint commitments to be meaningful.
Enterprise reality: Most large organisations use Scrum for development and Kanban for operations and support. Understanding both — and how they interact across the delivery pipeline — is a core CREA-SM competency.
