ITPEC IP October 2021 Question 70

Listening to free-wheeling opinions, including unique ideas — brainstorming welcomes any idea, however unusual, so that as many ideas as possible come out.

Brainstorming, devised by Alex Osborn, runs on four rules: no criticism (judgement is postponed until after the session), free-wheeling (unusual and wild ideas are welcome), quantity over quality (the more ideas the better), and combination and improvement (building on others' ideas). Option (d) is the free-wheeling rule.

Answer (d)

Why not others:

• •(a) — presenting only one's own high-quality ideas breaks quantity over quality; an idea that looks weak may spark a better one
• •(b) — criticism is exactly what brainstorming forbids while ideas are being generated; evaluation comes afterwards
• •(c) — building better ideas on another participant's idea is encouraged by the combination-and-improvement rule, not avoided

Key rule: Brainstorming's four rules are no criticism, free-wheeling, quantity over quality, and combine and improve; ideas are sorted and evaluated only after the session, for example with the KJ method.
