The Paradox of Brainstorming
Sadly, in most organisations that I have consulted to or worked in the managers leading brainstorms have not actually conducted them properly. Too often they have descended into untimed, chart lists and discussions where creativity has been the first victim. Where there is low trust between managers and their people or even their peers about the consequences of 'saying the wrong thing' then this veering away from true brainstorming leads to poor decisions and even poorer creative solutions.
Brainstorming is only fun if the rules are adhered to. It's the paradox of brainstorming
that there are a set of rules to help people break away from the corporate chains and think and share freely. It's no fun when it is done without sticking to the rules.
