Scrum runs work in fixed sprints of one month or less, with three set accountabilities (Product Owner, Scrum Master, Developers) and four planned events. Kanban has no sprints or required roles: work flows continuously across a board, and you cap how many items can be in progress at once. Pick Scrum when you need a regular rhythm and planned goals; pick Kanban when work arrives unpredictably and you need to react fast.
The difference that matters most day to day is change. In Scrum, the Sprint Goal stays fixed during the sprint, and new work usually waits for the next Sprint Planning. In Kanban, a new urgent task can start as soon as something else finishes and frees up a slot.
Kanban and Scrum side by side
| Scrum | Kanban | |
|---|---|---|
| Cadence | Fixed-length Sprints of one month or less, back to back | Continuous flow, no fixed iterations |
| Roles | Product Owner, Scrum Master, Developers | No required roles; you keep the ones you have |
| Change mid-cycle | The Sprint Goal doesn't change during the Sprint; scope can be clarified with the Product Owner | New work can be pulled in whenever capacity frees up |
| Planning | Sprint Planning at the start of every Sprint | Planning happens as needed, often in a regular replenishment meeting |
| Key measures | Progress toward the Sprint Goal and Product Goal | WIP, throughput, work item age and cycle time |
| Board | Sprint Backlog refreshed each Sprint | One board that keeps running; items move until done |
| Best for | Product work with a clear goal and room to plan ahead | Support, content and service work with steady, unpredictable demand |
Scrum's events are time-boxed. The 2020 Scrum Guide sets the Daily Scrum at 15 minutes and, for a one-month Sprint, caps Sprint Planning at 8 hours, the Sprint Review at 4 hours and the Retrospective at 3 hours. Shorter Sprints usually mean shorter events.
The catch people miss: a Kanban board without work-in-progress limits isn't Kanban, it's a to-do list with columns. The Kanban Guide treats controlling WIP as central. Without a limit, everything gets started and nothing gets finished, which is the exact problem Kanban is meant to fix.
Scrum also gives you three artifacts, each tied to a commitment: the Product Backlog serves the Product Goal, the Sprint Backlog serves the Sprint Goal, and each Increment has to meet the Definition of Done. Kanban asks for something simpler but just as strict: a written Definition of Workflow that says what your columns mean, when an item counts as started and when it counts as finished.
What a week looks like for a 5-person marketing team
The Scrum version
Say the team runs two-week Sprints. On Monday of week one, they hold Sprint Planning: the Product Owner (often the marketing lead) brings the priorities, and the team agrees a Sprint Goal, such as "launch the spring webinar landing page and email sequence". Every morning, they meet for a 15-minute Daily Scrum to check progress toward that goal and flag blockers. A sales request for a new case study arrives on Wednesday; it goes into the Product Backlog for the next Sprint unless it serves the current goal. At the end of week two, the team shows what they finished at the Sprint Review and talks about how to work better at the Retrospective. Then the next Sprint starts straight away.
The Kanban version
The same team keeps one board with columns such as Ideas, Ready, Writing, Design, Review and Published. Each active column has a limit, for example no more than three items in Writing at once. On Monday, they pull the next most important items into Ready. On Wednesday, the case study request arrives; it joins Ready, and as soon as a writer finishes a blog post, they pull the case study in. A short standup at the board each day focuses on what's stuck and what's ageing. Once a week, they look at how long items took from start to finish and adjust their limits.
If you want to try this without buying anything, a free Kanban board is enough to start with sticky-note style cards and column limits.
Scrumban: when to mix the two
Plenty of teams land somewhere in between. Scrumban usually means keeping a Kanban board with WIP limits while adding some Scrum habits, such as a regular planning meeting, a review of finished work and a retrospective. Neither guide defines Scrumban, so treat it as a practical blend rather than a framework with rules.
A mix makes sense when:
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
- You like Scrum's regular reviews but urgent work keeps breaking your Sprints.
- You run Kanban but want a fixed moment to step back and improve.
- Part of the team does planned project work and part handles requests.
- You're moving from one method to the other and want a gentler change.
The risk with a blend is keeping the meetings from both and the discipline from neither. Decide which rules you're keeping, write them down and review them after a month.
How to choose in 4 questions
- Can you protect a goal for one to four weeks? If urgent requests land daily and can't wait, Kanban fits better. If you can hold most new work until the next planning session, Scrum works.
- Do you need a fixed rhythm for stakeholders? Regular Sprint Reviews give managers and clients a predictable moment to see progress. Kanban can do this too, but you have to schedule it yourself.
- Will someone own the priorities? Scrum depends on a Product Owner who orders the backlog. Without one, Scrum tends to drift.
- Are your items similar in size? Kanban's flow measures work best when items are broken into roughly comparable chunks. Big, uneven projects often suit Sprint-based planning better.
Whichever you pick, the method sits on top of the basics: scoping, scheduling, risk and communication. This guide to core project management processes covers those foundations, and this comparison of project management tools for small teams shows which apps support Scrum boards, Kanban boards or both.
My take
For most small marketing and service teams, I'd start with Kanban and strict WIP limits, because the work rarely arrives in tidy batches. If the team then wants more structure, I'd add a fortnightly review and retrospective before adopting full Scrum. Product teams building toward a clear launch are the exception, and they usually do well with Scrum from day one.
Frequently asked questions
Is Kanban or Scrum better for small teams?
Neither is better across the board. Kanban suits small teams with unpredictable, request-driven work. Scrum suits teams that can protect a goal for a Sprint and have someone to own priorities.
Does Kanban have sprints?
No. Kanban uses continuous flow instead of fixed iterations. Teams pull new work in whenever their WIP limits allow, though many still hold regular review meetings.
How long is a Scrum sprint?
The 2020 Scrum Guide says a Sprint is one month or less. Many teams choose one or two weeks, and a new Sprint starts as soon as the previous one ends.
Can you use Scrum and Kanban together?
Yes. Many teams use a Kanban board with WIP limits inside Scrum Sprints, or add Scrum-style reviews and retrospectives to Kanban. This blend is often called Scrumban.
