Know what you want, and what to do with it: if you are looking for a big raw list of news ideas to review later, then a plan for how you’ll review it. The simplest strategy is to plan an hour afterwards, for youself alone, to pull out the 5 or 10 most interesting ideas and examine them in detail. There is nothing worse for a team to feel their creative thinking falling into a back hole. You’ll get better ideas and more energy from people if they can see where it’s all going to go. At a minimum, say you don’t know what happens next, but give them a deadline for when they’ll get an update from you. If you fail to do so, don’t expect to be so creative at the next brainstorming session.
