Brainstorming BDAs

I Was trying out some of the brainstorming techniques in Indi Young's Mental Models with a new project. Specifically, the "Before, During, and After" for hypothesizing behaviors and framing audience segments. It turned out quite fruitful, especially given how quick and simple it was.

So then I was thinking, what are some of Dribbble's favorite brainstorming methods? Please, share!
