The problem with committee-based ideas
No one wants to sound stupid.
All ideas are treated as acceptable.
Everyone wants their own idea to be picked.
To save feelings, ideas are meshed together – and averaged.
No one in the room is (or is acknowledged to be) qualified for this particular task.
The result is usually just sufficient. Or worse.
Better to hire/appoint/select one qualified person to generate 3 ideas and present them.
