4: front it (host)
The most important role in a brainstorm is the host
They are there to:
a) Keep things ticking along - so people don't lose interest, you keep to time, and you maintain the energy in the room
b) Make sure everyone sticks to the brief, so that you all leave the session having achieved the original purpose
c) Get everyone involved, so you don't miss out on the talent that's sitting in the room (particularly the more quiet and shy ones!)
DOs and DON'Ts for the host:
DO encourage all ideas! The more the merrier
DON'T comment negatively on any of them. Your experience might tell you it won't work, but if you said that out loud in a brainstorm, you will put people off speaking up, and that way you could lose out on some gems
DO listen out for those gems - someone could make a comment and whilst it's not the idea, it could be the germ of an idea.
Write it down, and dig a little deeper.
E.g. "There's something in that. Let's take a moment to all think a bit more about that bit - could we extend it? How could it play out? Maybe it's not quite right as a traditional media story, but is it a good activity for social?"
DON'T let individuals dominate or go off on a tangent - sometimes someone might love an idea they've had and get really into it.
But if it's off brief, you're wasting time.
Try to bring them back round to your written brief and the objectives set out in it, but in a non-critical way.
E.g. "That would be GREAT if we could do that. Unfortunately for THIS particular brief, we do need to stick to something that will do X. So let's get back to thinking about that for now...."
DO give people 'signposts' that help them follow your line of thinking.
E.g.
OK - so we've established what the campaign needs to do, we've established who the main audience is, and we've got some lovely insights into what motivates them. Now we can get into tactics - WHAT should we communicate and what is the best way to do it, considering what we know about the audience and the brief?
NOW, it doesn't have to be you! You might be the account lead for the thing you're brainstorming, but sometimes it's better to approach someone else and ask them to facilitate. The benefit of that is they can be objective - they don't bring into the brainstorm any prior 'baggage' about the client or what has gone well or not so well in previous campaigns on that account.
