Capacity and sprint planning
Sprint Capacity vs Velocity
A practical comparison of sprint capacity and velocity, what each one is trying to show, and why teams get into trouble when they use one as a substitute for the other.
Start with the difference
Sprint capacity is a forward-looking view of what the team realistically has available in the next sprint.
Velocity is a backward-looking view of how much work the team has completed in past sprints. One helps shape the upcoming commitment. The other helps add historical context to it.
Capacity vs velocity
Capacity looks forward while velocity looks back, and sprint planning breaks when teams use one as the other.
Velocity
Velocity is a historical signal about past delivery, not current sprint room.
Forward-looking capacity
Capacity describes what this sprint can realistically absorb.
Historical velocity
Velocity adds context, but it does not replace current availability.
Mix-up risk
Planning gets distorted when past averages override present constraints.
Use both well
The healthiest teams use velocity for context and capacity for the actual commitment.
What sprint capacity is trying to answer
Capacity asks a very practical planning question: how much usable delivery time does the team actually have this sprint after time off, meetings, support work, and reduced focus time are counted?
It is grounded in the real conditions of the next sprint, not just the team's usual pace in a perfect average week.
What velocity is trying to answer
Velocity asks a different question: how much work has this team typically completed across recent sprints?
That makes it useful as a historical signal, especially when the team wants a rough sense of its past delivery rhythm.
Why teams confuse them
Teams often confuse capacity and velocity because both seem to answer "how much can we take on?"
But they answer it from different directions. Velocity looks at what happened before. Capacity looks at what is true now in the next sprint's actual working conditions.
Where capacity usually helps more
Capacity is more useful when the team's availability changes from sprint to sprint or when time off, meeting load, and support work meaningfully affect what fits.
It helps prevent the team from blindly using a historical average in a sprint that has very different real constraints.
- Useful when team availability changes.
- Useful when time off is significant.
- Useful when meeting or support load is unusually high.
Where velocity still adds value
Velocity can still help as a historical reference point. It can tell the team whether the planned sprint size is wildly out of line with what it has usually completed.
The problem starts when velocity is treated like a fixed capacity number instead of a lagging indicator with context around it.
What usually goes wrong
Planning gets distorted when the team uses velocity as if it automatically defines the next sprint's capacity, or when capacity is ignored because the past average feels easier to trust than current reality.
- Historical velocity overrides obvious current constraints.
- Time off and meetings are ignored.
- The team commits to the average instead of the actual sprint.
- Capacity becomes decorative instead of decision-making input.
Where to go next
If your team keeps defaulting to historical averages without checking whether the next sprint actually has room for that much work, the capacity tool is the best next step.
That is where the team can turn real availability into a more honest commitment before the sprint starts.
TL;DR
- Sprint capacity looks forward at actual availability in the next sprint.
- Velocity looks backward at what the team completed in past sprints.
- Velocity is useful context, but it should not replace current capacity.
- Teams plan more honestly when capacity shapes the next sprint and velocity stays a historical signal.
