IPA IP 2025 Question 46
A question IPA Japan published in 令和7年度 ITパスポート試験 公開問題 問46, translated into English. ITPEC is based on the same exams.
Which of the following is the appropriate process in which the procedure for installing software whose development has been completed in the production environment is clarified, and the installation is carried out?
Explanation
Software installation — the development process that plans how the finished software goes into the production environment and then installs it there.
In the software life cycle processes, software installation draws up an installation plan (the steps, the schedule, the resources, how to switch over from the old system and how to restore it if something fails), agrees it with the people concerned, and carries it out in the production environment. It comes after the software has been built and tested, and before acceptance by the users.
Answer (b)
Why not others:
- •(a) — software integration combines the software units and components into the whole software and tests them together (integration testing), still in the development environment
- •(c) — validation confirms that the system meets its intended use and the users' needs; it checks the result, it does not install it
- •(d) — user education trains the users to operate the new system
Key rule: Integration = combine and test the parts; installation = plan and carry out the move into production; validation = confirm it meets the intended use; acceptance = the users accept it.
