Michael is planning on using brainstorming in his next team meeting to generate new ideas for expanding a product line.In using brainstorming effectively,Michael should:

A) articulate the theme.
B) allow for unlimited time.
C) keep the identity of all idea contributors confidential.
D) remember that quality is more important than quantity.

Brainstorming is most effective when there's a clear theme or problem statement that guides the ideation process. This helps participants focus their thoughts and creativity towards a specific goal or challenge, making the session more productive. Options B, C, and D are not recommended practices for effective brainstorming. Unlimited time can lead to diminishing returns, confidentiality can hinder open collaboration, and emphasizing quantity over quality initially is important to generate a wide range of ideas, which can later be refined.
