Is a Group Brainstorm a Good Way to Write?

i've been saying forever that i don't believe that a group brain storms are productive. I fe like a general brain storm. And they do thar, all sorts of things. It's a girls love doing general brain storms,. And i've had po jects i'm working on where everyone's always like, less to a general brainstrom. But if you have some sort of outline for stuff, and then, even like s and l theire pitches, you know, you show up and you ave all these pitches, and then you pitch them exactly, yes?
