Entry Certificate in Business Analysis (ECBA) — Question 69

What is the optimum group size for brainstorming?

Answer options

• A. It doesn't matter how many individuals as long as the project manager is included
• B. The more individuals the better
• C. Six to eight individuals who represent a range of backgrounds
• D. A maximum of three individuals with a deep knowledge of the subject

Correct answer: C

Explanation

The correct answer, C, suggests that a group of six to eight individuals with varied backgrounds fosters diverse ideas and perspectives, enhancing creativity. Option A is incorrect because excluding diverse inputs limits brainstorming effectiveness. Option B fails to recognize that too many participants can lead to chaos rather than productive discussion. Option D restricts the group size too much, reducing the potential for varied ideas.
