We will be using Edward de Bono’s form of parallel thinking known as the Six Thinking Hats. The intention is to discover as much information about a topic as possible. It is highly recommended that you read the book [1].
de Bono quotes an impressive list of companies that have used this method apparently with extraordinary success: Siemens, IBM, NASA, DuPont, Shell, BP and others.
The coloured hats are intended to enable parallel thinking rather than argument. de Bono contrasts argument, which is concerned with discovering “what is”, with another form of thinking that is concerned with “what can be”, which involves constructive thinking, creative thinking and “designing a way forward”.
It is intended that everyone uses the same coloured hat at the same time. You are strongly discouraged from having a black group, a red group and so on. The idea is to make maximum use of parallel thinking: everyone pursuing the same aspect of the issues.
Each colour is used for a short time, a few minutes, and then a switch is made to another colour. We will probably break the class into small groups of 2 or 3 people and when we switch colour give each team a couple of minutes to develop ideas for that colour.
Not all colours need to be used and the same colour may be used more than once.
It is suggested that you begin and end with Blue.
It is important that the process be regarded as a game with everyone obeying the rules, that is everyone should be in synchrony with the current colour.
All points should be recorded on the board.
Notice that the Blue hat is a control hat and is therefore responsible for organising the overall discussion. The facilitator has a permanent Blue hat role, but everyone else in the class should take on the current colour. We could appoint one small team to have a permanent Blue role, perhaps ensuring that other teams are contributing effectively. The Blue team would be responsible for writing conclusions on the board. The Blue team could rotate.
