Learned this long ago. As a school administrator, I used brainstorming more as a step to create “buy in” than to actually get the jobs done. I would often discover a few new ideas that way, but after the brainstorming session the project was almost always completed by individuals doing specific tasks alone. The staff felt satisfied that they’d been heard and made a contribution when we brainstormed initially. But we stopped doing “group projects” because the process was inefficient and sometimes caused a great deal of conflict.
