Kanban vs Scrum: which one should your team actually use?
Scrum plans in fixed batches, Kanban manages a continuous flow. The right answer depends on one thing: how predictable your incoming work is.
Kanban and Scrum get argued about as if they were rival religions. They're both just ways of limiting how much your team does at once — they differ in how they do the limiting.
The actual difference
Scrum limits by time. You commit to a set of work for a fixed period, usually two weeks, and try not to change it mid-sprint. That protection from change is the whole point.
Kanban limits by quantity. There's no sprint; work flows continuously, and each column has a WIP limit — a cap on how many items can sit in it at once. When a column is full, you finish something before starting something new.
Choose by how predictable your work is
Scrum fits when you can plan two weeks ahead with a straight face: product work, feature development, a roadmap that doesn't change daily.
Kanban fits when work arrives unpredictably: support, ops, agencies, bug-heavy periods. Committing to a two-week plan you'll abandon on day three teaches everyone that plans are theatre.
A simple test: if you routinely break into your sprint, you don't have a sprint — you have a Kanban board with a two-week meeting attached.
What each one costs you
Scrum's overhead is meetings: planning, review, retro, and enough estimating to make planning meaningful. In exchange you get a forecast — velocity tells you roughly what fits in the next two weeks.
Kanban's overhead is discipline. There's no ceremony forcing you to look at the board, so without WIP limits it degrades into a to-do list where everything is in progress and nothing finishes. Kanban without WIP limits isn't Kanban.
The hybrid most teams land on
Plenty of good teams run something in between, and that's fine:
- Two-week sprints for planned work, with a reserved slice of capacity for interrupts.
- A Kanban board with WIP limits, plus a monthly planning session for direction.
- Scrum for the product team, Kanban for the support rotation, one shared board.
Nobody is grading you on methodology purity. The question is whether the team can see what's in flight and finish things.
Supporting either one
Your tracker shouldn't force the choice. VectorKan supports both: custom workflow columns and per-column WIP limits for Kanban, sprints with burndown and velocity for Scrum, and both at once if that's what your team needs. Start with whichever matches your work today — you can change your mind in a month without changing tools.
Frequently asked questions
What is the main difference between Kanban and Scrum?
Scrum limits work by time — a fixed commitment for a fixed sprint length. Kanban limits work by quantity, using WIP limits on each column, with work flowing continuously and no sprints.
Which is better for a support team, Kanban or Scrum?
Kanban, generally. Support work arrives unpredictably, so committing to a two-week plan you'll be interrupted out of creates friction without adding value.
Can you use Kanban and Scrum together?
Yes — it's common. Teams often run sprints for planned work while using WIP limits to manage flow, or run Scrum for product work and Kanban for a support rotation.
What are WIP limits?
A cap on how many items can be in a column at once. When the column is full, the team finishes something before starting anything new. They're what makes Kanban work; without them the board becomes a to-do list.
