問 53
Incorrectア
An interview is a survey technique in which you directly ask a subject questions and gather their opinions and information. It is a technique for collecting information individually, not a method for grouping collected ideas and organizing them systematically, so it is incorrect.
- イ
正解 The correct answer is “イ Affinity diagram method”. The affinity diagram method (KJ method) is a technique for taking a large amount of collected language data such as opinions and ideas, grouping it by content affinity (putting similar items together), giving each group a heading, and organizing everything systematically. It matches exactly the stem’s description of grouping the results of ideas generated collectively by a team and organizing them systematically, so it is the correct answer.
Incorrectウ
Brainstorming is an idea-generation technique in which a group freely throws out ideas under the principles of no criticism, free-wheeling thinking, quantity over quality, and welcoming build-on (extending others’ ideas). It is a method for the stage of producing ideas, not for grouping and organizing the resulting ideas, so it is incorrect (it is combined with the affinity diagram method during the organizing stage).
Incorrectエ
A prototype (trial product) is a method and deliverable in which a simple trial model is built in the early stage of development to confirm and verify requirements or specifications. It is not a method for grouping and organizing ideas, so it is incorrect.
- Affinity diagram method (KJ method): a technique that groups a large amount of language data (opinions and ideas) by affinity, gives each group a heading, and organizes them systematically.
- Distinguish the difference in roles: brainstorming is an idea-generation technique for producing ideas, whereas the affinity diagram method is a technique for organizing the results that have been produced.
