解説
問 50
Incorrectア
“It works even if the OS of the PC on which the RPA runs changes” refers to the ability to keep working after being moved to a different environment, which describes “portability,” not usability.
Incorrectイ
“Automated processing is executed appropriately based on the time and conditions specified in the RPA” states that the required function is correctly fulfilled, which describes “functional suitability,” not usability.
Incorrectウ
“Even if the application software targeted by the RPA is upgraded, it can be handled with a simple setting change” states that it is easy to modify and adapt to changes, which describes “maintainability,” not usability.
- エ
正解 The correct answer is エ. “Usability” is the quality characteristic that expresses how easily a user can understand, learn, and operate the software. Choice エ, “Even a person who has never used RPA can become able to use it with only simple training,” describes exactly this ease of learning and ease of use, so it corresponds to usability.
ここがポイント
- In ISO/IEC 25010, the quality characteristic “usability” means how easily users can understand, learn, and operate the software. The choice describing that little effort is needed to learn it is the correct one.
- In questions that map each choice to a quality characteristic, distinguish them as: portability = moving to another environment, functional suitability = realizing the correct function, maintainability = ease of coping with changes.
