Freethinking and Pre-Planning
Even if the bulk majority of your brainstorming is going to happen during a group meeting, you still need to come to that meeting already prepared with some ideas ready to go. The pre-planning phase is just as important; in this part of the brainstorming process, it’s all about you.
Use a pad of paper or wipeboard to jot down any idea that comes to mind–and that means any. Your goal is not to come up with a fully developed idea right away but to build towards something amazing by letting your ideas flow freely. When you’re done, take a look at what you’ve come up with and you’ll have a better understanding of what works and what doesn’t before you even attempt a group brainstorm.
