Tomorrow I run a creative problem solving exercise with 7 colleagues : perhaps i should make that 8. I have 90 minutes. Not an afternoon or a weekend. How much can i fit in? Or should that be how simple should I keep it? Using techniques I have taken part in or even done? Or do try something else? I have to facilitate but am also the most informed when it comes to the problem and its context so how do I remain detached and in charge?
