Every Sprint must be one month or less. Sprint length is a fixed timebox chosen for consistency, not stretched to fit the work planned in Sprint Planning.
Exam Question
Which of the following are true about the length of the Sprint?
(choose the best answer)
A. All Sprints must be one month or less.
B. The length of the Sprint should be proportional to the work that is done in between Sprints.
C. Sprint length is determined during Sprint Planning, and should be long enough to make sure the Scrum Team can deliver what is to be accomplished in the upcoming Sprint.
D. Sprint length is determined during Sprint Planning, and should hold the time it will take to build the planned features in the upcoming Sprint, but does not include time for any testing.
Correct Answer
A. All Sprints must be one month or less.
Why This Is the Correct Answer
The Scrum Guide states that “Sprints are fixed length events of one month or less to create consistency.” A new Sprint begins right after the previous one ends, so there is no gap “between Sprints” for work to happen in. Keeping Sprints short limits risk: the Guide explains that when a Sprint’s horizon is too long, the Sprint Goal may become invalid, complexity may rise and risk may increase. Sprint Planning decides what fits inside the Sprint, not how long the Sprint will be. Testing and all other work needed to meet the Definition of Done happen inside the same Sprint.
Why the Other Options Are Wrong
B. Sprint length is proportional to work done between Sprints. There is no time between Sprints. The next Sprint starts immediately after the previous one concludes.
C. Sprint length is set in Sprint Planning to fit what must be delivered. This flips the timebox around. The Sprint length is fixed, and the team selects work that fits it.
D. Sprint length is set in Sprint Planning and excludes testing. Testing is part of meeting the Definition of Done. Leaving it out would produce work that is not an Increment.
Exam Tip
If an option lets the length of a timebox depend on the amount of work, it is wrong. In Scrum the timebox is fixed and scope flexes.
Key Takeaways
- Sprints are one month or less and have a fixed length.
- A new Sprint starts right after the last one ends.
- All work for a Done Increment, testing included, happens inside the Sprint.
