7 min read
Choosing between Kanban and Scrum depends on your team's work patterns, delivery cadence, and organizational culture. GitScrum supports both methodologies fully, enabling teams to start with one approach and evolve their process as they learn what works best for their specific context.
Comparison Overview
| Aspect | Scrum | Kanban |
|---|---|---|
| Cadence | Fixed sprints (1-4 weeks) | Continuous flow |
| Planning | Sprint planning events | Just-in-time prioritization |
| Roles | Defined (PO, SM, Dev Team) | Flexible |
| Changes | Sprint backlog frozen | Change anytime |
| Metrics | Velocity, burndown | Lead time, throughput |
| Best for | Product development | Operations, support |
Decision Framework
METHODOLOGY SELECTION GUIDE
QUESTION 1: WORK PREDICTABILITY
┌─────────────────────────────────────────────────┐
│ Is your incoming work predictable? │
│ │
│ Mostly planned features → SCRUM │
│ Mix of planned and interrupt → SCRUMBAN │
│ Mostly reactive/support → KANBAN │
└─────────────────────────────────────────────────┘
QUESTION 2: RELEASE CADENCE
┌─────────────────────────────────────────────────┐
│ How do you release? │
│ │
│ Regular releases every 2-4 weeks → SCRUM │
│ Continuous deployment daily → KANBAN │
│ Mixed: features + hotfixes → SCRUMBAN │
└─────────────────────────────────────────────────┘
QUESTION 3: PRIORITY STABILITY
┌─────────────────────────────────────────────────┐
│ How often do priorities change? │
│ │
│ Stable for 2-4 weeks → SCRUM │
│ Changes within days → KANBAN │
│ Occasional mid-sprint changes → SCRUMBAN │
└─────────────────────────────────────────────────┘
QUESTION 4: TEAM MATURITY
┌─────────────────────────────────────────────────┐
│ Team's agile experience? │
│ │
│ New to agile, needs structure → SCRUM │
│ Experienced, self-organizing → KANBAN │
│ Experienced, wants flexibility → SCRUMBAN │
└─────────────────────────────────────────────────┘
QUESTION 5: STAKEHOLDER EXPECTATIONS
┌─────────────────────────────────────────────────┐
│ What do stakeholders expect? │
│ │
│ Regular demos, predictable dates → SCRUM │
│ "Just get it done" flexibility → KANBAN │
│ Both structure and flexibility → SCRUMBAN │
└─────────────────────────────────────────────────┘

Migration Paths
TRANSITIONING BETWEEN METHODOLOGIES
SCRUM → KANBAN:
┌─────────────────────────────────────────────────┐
│ 1. Keep sprint cadence but add WIP limits │
│ 2. Relax sprint commitment to flow │
│ 3. Replace velocity with lead time tracking │
│ 4. Move from sprint planning to replenishment │
│ 5. Keep retros, make other ceremonies optional │
└─────────────────────────────────────────────────┘
KANBAN → SCRUM:
┌─────────────────────────────────────────────────┐
│ 1. Introduce timeboxes (2-week iterations) │
│ 2. Add sprint planning ceremony │
│ 3. Commit to sprint backlog (no mid-sprint add)│
│ 4. Introduce demos at end of sprint │
│ 5. Track velocity instead of lead time │
└─────────────────────────────────────────────────┘
EITHER → SCRUMBAN:
┌─────────────────────────────────────────────────┐
│ Take what works from each: │
│ From Scrum: Sprint rhythm, demos, retros │
│ From Kanban: WIP limits, flow visualization │
│ │
│ Customize for your context │
