IPA FE Subject A sample Question 41
A question IPA Japan published in 基本情報技術者試験 科目A サンプル問題 問41, translated into English. ITPEC is based on the same exams.
Among the rules for the sprint in Scrum of agile development, which of the following is appropriate?
Explanation
Setting the sprint goal so that each sprint produces a releasable product increment — in Scrum every sprint ends with a usable piece of the product.
A sprint is a time-box of one month or less whose length is fixed for the project and kept the same from sprint to sprint. In sprint planning the team sets a sprint goal and chooses the backlog items that achieve it. Within the sprint it does all the work those items need, from analysis and design to coding and testing, so that at the end there is an increment good enough for the product owner to decide whether to release it. The sprint review then inspects that increment with the stakeholders.
Answer (c)
Why not others:
- •(a) — giving each sprint one phase (requirements, then design, coding, testing) is the waterfall model cut into time-boxes; a Scrum sprint covers every activity and ends with a working increment
- •(b) — the sprint review is held at the end of the sprint, to inspect the finished increment, not at its midpoint
- •(d) — the sprint length is decided once for the project and kept consistent; it is not reset in each sprint planning to suit the goal's difficulty
Key rule: A Scrum sprint is a fixed-length time-box that builds a releasable increment toward a sprint goal; the review comes at its end.
