Scrum vs Kanban: Differences and How to Choose
Scrum or Kanban? Compare the two most popular agile approaches side by side – sprints vs flow, roles, boards and metrics – see real Scrum, Kanban and Scrumban boards, and use a simple decision guide to choose, combine or switch.
Quick answer: Scrum and Kanban are both agile approaches. Scrum organises work in fixed-length sprints with a Product Owner, Scrum Master and set events; Kanban manages a continuous flow of work on a visual board with work-in-progress (WIP) limits and no required roles. Choose Scrum for planned product increments, Kanban for unpredictable or ongoing work, or combine them as Scrumban.
1. Key Takeaways
- Scrum organises work in fixed sprints with three roles and four events; Kanban manages a continuous flow with WIP limits and no required roles.
- Scrum and Kanban in agile: both are agile approaches – Scrum is a framework, Kanban is a method for improving flow.
- Choose Kanban over Scrum when work arrives unpredictably or priorities change daily; choose Scrum for planned product increments.
- Kanban for Scrum teams keeps sprints but adds WIP limits and flow metrics – a popular middle ground.
- Scrumban combines Scrum’s rhythm with Kanban’s pull system.
- Moving from Scrum to Kanban (or Kanban to Scrum) works best in small, evolutionary steps.
2. Scrum vs Kanban: The Short Answer
Scrum and Kanban are both agile ways of managing work: Scrum plans work in fixed-length sprints with defined roles and events, while Kanban manages a continuous flow of work on a visual board with work-in-progress limits. Scrum asks “what can we finish this sprint?”; Kanban asks “what should we pull next?”
Neither is better in every situation. The right choice depends on how predictable your work is, how your team is organised and how often priorities change – and many teams end up using a mix of Scrum and Kanban.
3. What Is Scrum?
Scrum is an agile framework in which a small team delivers work in fixed-length iterations called sprints, usually two weeks long, guided by a Product Owner and a Scrum Master.
- Roles (accountabilities): Product Owner, Scrum Master and Developers.
- Events: Sprint, Sprint Planning, Daily Scrum, Sprint Review and Sprint Retrospective.
- Artifacts: Product Backlog, Sprint Backlog and Increment, each with a commitment (Product Goal, Sprint Goal, Definition of Done).
Scrum is defined in The Scrum Guide by Ken Schwaber and Jeff Sutherland.
4. What Is Kanban?
Kanban is a method for managing and improving the flow of work: tasks are visualised as cards on a board, each step has a work-in-progress limit, and new work is pulled only when there is capacity.
It started in Toyota factories and was adapted to knowledge work by David J. Anderson. The Kanban Guide describes three practices: defining and visualising a workflow, actively managing items in the workflow, and improving the workflow. There are no sprints and no required roles – you start with the process you have.
5. Scrum and Kanban in Agile
Scrum and Kanban in agile are two of the most widely used ways to put the Agile Manifesto into practice: both deliver value in small pieces, welcome change and improve continuously, but they organise time differently.
Agile is the mindset; Scrum and Kanban are concrete ways of working. That is why people search for “agile Scrum and Kanban” or “agile Scrum Kanban” together – most agile teams use ideas from both, even if they call their process by one name.
Both methods. One place to run them.

6. Kanban vs Scrum: Key Differences
The key differences between Kanban and Scrum are cadence (continuous flow vs sprints), roles (none required vs three accountabilities), how work is limited (WIP limits vs sprint capacity) and how change is handled (any time vs between sprints).
| Scrum | Kanban | |
|---|---|---|
| Origin | Software (Schwaber & Sutherland, 1990s) | Manufacturing (Toyota), adapted to software in the 2000s |
| Cadence | Fixed sprints of 1–4 weeks | Continuous flow |
| Roles | Product Owner, Scrum Master, Developers | No required roles |
| Events | Sprint planning, Daily Scrum, Sprint Review, Retrospective | Optional cadences, e.g. daily meeting, replenishment |
| Limits work | Sprint capacity (what fits in the sprint) | WIP limits per column |
| Changes | Usually wait until the next sprint | Any time, when capacity frees up |
| Release | At least once per sprint | Whenever an item is done |
| Key metrics | Velocity, burndown | Lead time, cycle time, throughput, CFD |
| Board | Reset each sprint | Persistent |
| Best for | Product development with a roadmap | Support, operations, maintenance, mixed or unpredictable work |
In practice, “Kanban vs Scrum” is less about rules and more about rhythm. Scrum creates a heartbeat of commitments every sprint; Kanban creates a steady stream of finished work.
7. Scrum and Kanban Board Examples
The clearest way to see the difference between Scrum and Kanban is to compare real boards. Here are four boards built in PlanBoards.
Kanban board: continuous flow
A mobile team pulls work from Backlog through Ready, In Progress and Review. Each column has a WIP limit and nothing resets – items ship whenever they reach Done.
Scrum board: a two-week sprint
The sprint starts with a Sprint Goal card and a committed Sprint Backlog with story points. A burndown chart shows remaining work, and the board is cleared at the end of the sprint.
Scrumban board
A data team keeps a short planning rhythm but refills its Next list only when it drops below three items, and limits Doing to three.
Kanban for Scrum teams
A Scrum team keeps its sprint but adds WIP limits to Dev, Code Review and QA so items finish during the sprint instead of piling up at the end.
8. When to Choose Kanban over Scrum
Choose Kanban over Scrum when work arrives unpredictably, priorities change often, the team handles a mix of small tasks or you want to improve your current process without reorganising the team.
- Support, IT operations, DevOps and maintenance teams.
- Marketing, content, design and agency teams with many small requests.
- Small teams without a dedicated Scrum Master or Product Owner.
- Teams that find sprint planning slow or artificial.
- Personal productivity and non-software teams such as HR, finance or operations.
9. When Scrum Is the Better Fit
Scrum is the better fit when a dedicated team builds a product in planned increments, benefits from a fixed rhythm of planning and review, and has stakeholders who want a predictable demo every sprint.
- New product development with a clear Product Goal.
- Teams that need structure and protected focus time.
- Organisations that want clear roles and accountability.
- Projects where regular stakeholder feedback shapes the next increment.
10. How to Choose: Scrum or Kanban?
To choose between Scrum and Kanban, look at how predictable your work is, whether you build a product or run a service, whether you can fill Scrum roles and how often urgent work interrupts the team.
If the answers point both ways, start with Kanban on your current process, add a regular planning and review rhythm, and you have Scrumban – a practical middle ground.

11. Kanban for Scrum Teams
Kanban for Scrum teams means keeping Scrum’s sprints, roles and events while adding Kanban practices: a visualised workflow, WIP limits, active management of work items and flow metrics.
Scrum.org describes this approach in The Kanban Guide for Scrum Teams. The benefits are fewer half-finished stories at the end of the sprint, earlier detection of bottlenecks and better forecasts using cycle time instead of only story points. Used this way, Kanban does not replace Scrum – it strengthens it.
12. Scrumban: Combining Scrum and Kanban
Scrumban combines Scrum and Kanban: it keeps a light planning rhythm, stand-ups and retrospectives from Scrum and adds WIP limits, a pull system and a persistent board from Kanban.
People search for this mix under many names – “Scrum of Kanban”, “Kanban of Scrum” or simply “Scrum Kanban” – but the common name is Scrumban, a term coined by Corey Ladas.
A typical Scrumban rule is “plan on demand”: the team holds a planning session whenever the Ready column drops below a set number of items, rather than at fixed sprint boundaries. Scrumban is a good option for Scrum teams that also handle support work, and for Kanban teams that want more rhythm.
13. From Scrum to Kanban (and Kanban to Scrum)
The safest way to move from Scrum to Kanban is evolutionary: keep your board and rituals, add WIP limits, replace sprint planning with on-demand replenishment and switch from velocity to flow metrics.
- Visualise your sprint board as a flow. Keep your columns but treat the board as permanent instead of resetting it every sprint.
- Measure current WIP. Count how many items are in each column for two weeks.
- Add WIP limits. Set limits slightly below today’s average WIP.
- Replace sprint planning with replenishment. Refill the Ready column whenever it drops below a threshold.
- Swap velocity for flow metrics. Track cycle time and throughput instead of story points.
- Keep the good rituals. Keep the daily stand-up and retrospectives if they help the team.
Moving from Kanban to Scrum
Going from Kanban to Scrum is less common but useful when a team starts building a new product. Introduce a Product Owner, group work into a Product Goal, choose a sprint length and hold the four Scrum events – while keeping your WIP limits on the board.
14. Running Scrum or Kanban in PlanBoards
PlanBoards works for Scrum, Kanban and Scrumban: create a board per sprint or one persistent board, add WIP limits to list names and track work with labels, story points in titles, due dates and checklists.
- For Scrum: lists for Product Backlog, Sprint Backlog, In Progress, Review and Done; a Sprint Goal card at the top; duplicate the board for each sprint.
- For Kanban: one persistent board, WIP limits in list names, a Waiting or Blocked label and colour labels for work types.
- For Scrumban: add a refill rule to the Ready list name, such as “Next · refill at 3”.
15. Scrum vs Kanban FAQ
These are the questions people ask when they compare Scrum and Kanban and decide which to use.
What is the main difference between Scrum and Kanban?
Scrum organises work in fixed-length sprints with defined roles and events, while Kanban manages a continuous flow of work using a visual board and work-in-progress (WIP) limits, with no required roles or sprints.
Is Kanban better than Scrum?
Neither is better in general. Kanban suits work that arrives unpredictably, such as support, operations and maintenance. Scrum suits teams building a product in planned increments. Many teams combine them as Scrumban.
Can you use Scrum and Kanban together?
Yes. Scrum teams often use a Kanban board with WIP limits inside their sprints, and the hybrid of Scrum events with Kanban flow is called Scrumban.
Are Scrum and Kanban both agile?
Yes. Both are agile approaches: they deliver work in small pieces, welcome change and improve continuously. Scrum is a framework; Kanban is a method for improving flow.
Does Kanban have sprints?
No. Kanban has no sprints. Work is pulled continuously and released whenever it is ready, although teams can hold regular planning and review meetings.
Does Kanban have roles like Scrum Master?
No roles are required in Kanban. Some teams add optional roles such as a service delivery manager, but you can start with your current roles.
What is Kanban for Scrum teams?
Kanban for Scrum teams means keeping Scrum’s sprints and events while adding Kanban practices: visualising the workflow, WIP limits, active management of work items and flow metrics. Scrum.org publishes a guide on this approach.
How do I switch from Scrum to Kanban?
Keep your board, measure current WIP, add WIP limits, replace sprint planning with on-demand replenishment, track cycle time and throughput instead of velocity, and keep useful rituals such as retrospectives.
Which is easier to start with, Scrum or Kanban?
Kanban is usually easier to start because you begin with your current process and change it gradually. Scrum requires new roles, events and a sprint cadence from day one.
Should a small team use Scrum or Kanban?
Small teams often prefer Kanban because it needs no dedicated Scrum Master or Product Owner. If the team builds a product with a clear roadmap and likes a fixed rhythm, Scrum or Scrumban can work well too.
