Execution & Delivery
What is Sprint?
A Sprint is a fixed-length event of one month or less in Scrum. The team plans work around a Sprint Goal, inspects progress in Daily Scrums, reviews the result with stakeholders, and discusses improvements in a retrospective. The goal is the commitment; the planned work can be clarified as the team learns.
Formula
Sprint Capacity = Team Size x Days per Sprint x Focus FactorThis optional planning estimate uses a Focus Factor to account for meetings, interruptions, and other work. Choose it from team availability rather than treating it as a Scrum requirement. Example: 5 engineers, 10-day sprint, 70% focus. Capacity = 5 x 10 x 0.7 = 35 person-days. Sprint goal: one clear, measurable outcome that anchors the sprint beyond a list of tickets.
Benchmarks and interpretation
- Sprint length: one month or less, with a consistent duration
- Sprint Planning: at most 8 hours for a one-month Sprint
- Daily Scrum: 15 minutes
- Sprint Review: at most 4 hours for a one-month Sprint
- Sprint Retrospective: at most 3 hours for a one-month Sprint; events are usually shorter for shorter Sprints
When to use Sprint
- Structuring a development cycle with a clear start, end, and deliverable for each iteration
- Creating regular cadences for stakeholder communication through sprint reviews
- Breaking a large feature into sprint-sized chunks to enable continuous progress checks
- Establishing a continuous improvement rhythm through retrospectives
Common mistakes
- Accepting changes that endanger the Sprint Goal; scope can be clarified and renegotiated as the team learns
- Skipping retrospectives when teams are busy, losing the primary mechanism for process improvement
- Listing features without explaining the shared objective for the Sprint
Practical tips
- Write a clear Sprint Goal so the team can use it to guide decisions when the planned work needs to change.
- Allow for unplanned work and bug fixes using the amount your team has needed in recent sprints
- Rotate retrospective facilitation across team members to keep the format fresh and surface different perspectives
