IPA IP 2026 Question 43

A question IPA Japan published in 令和8年度 ITパスポート試験 公開問題 問43, translated into English. ITPEC is based on the same exams.

A company is planning the development of application software for smartphones, and has decided to repeatedly release a new version that includes new functions and corrections of defects every 2 weeks. The policy is that candidates for new functions and defects are managed in a list, developed in order of priority, and released one after another. Which of the following is the most appropriate software development model to be adopted for this development?

Explanation

Agile — short fixed cycles that each release working software, driven by a prioritized list of work, are the marks of agile development.

The story has every feature of agile development (Scrum in particular):

  • •a new version every 2 weeks: short iterations (sprints) of fixed length
  • •new functions and defects kept in one list: the product backlog
  • •developed in order of priority and released one after another: each iteration takes the most valuable items from the top of the list

Answer (b)

Why not others:

  • •(a) — DevOps is the collaboration of the development and operations sides, with automated testing and deployment, to release quickly and reliably; it supports frequent releases but is not the model that plans work from a prioritized list in fixed cycles
  • •(c) — waterfall runs the phases once, in order, and delivers the whole system at the end, not a new version every 2 weeks
  • •(d) — reverse engineering analyzes existing software to recover its specifications or design; it is not a development model

Key rule: Short iterations, a prioritized backlog and frequent releases mean agile; DevOps is about development and operations working together to deliver those releases.
