Have a Brainstorming Session Coming Up?

Have a brainstorming session coming up to discuss ideas for your next campaign?
Aside from loads of colorful sticky notes, of course, here's a few other "things" to make sure the team know to bring ahead of the session:
1) Their understanding of why you are all brainstorming to begin with...
2) Their understanding that thinking outside of the box should be both fun and challenging...
3) Their understanding that a collaborative environment means [everyone] sharing ideas and [everyone] listening intently to go off on teammates' ideas...
Go get 'em!
