The Six Hats of Thinking enables groups to look at a decision from several points of view. It was created by Edward de Bono in his book Six Thinking Hats and is an important and powerful technique. The tool is used to look at decisions from a number of important perspectives. This forces participants to move outside a habitual thinking style and helps achieve a more rounded view of a situation.

Many successful people think from a very rational, positive viewpoint: this is part of the reason they are successful. Often, though, they may fail to look at a problem from an emotional, intuitive, creative or negative viewpoint. This can mean that they underestimate resistance to plans, fail to make creative leaps, and do not make essential contingency plans. Similarly, pessimists may be excessively defensive; more emotional people may fail to look at decisions calmly and rationally.

If you look at a problem with the Six Thinking Hats technique, you will be able to solve it using all approaches. Your decisions and plans will mix ambition, skill in execution, public sensitivity, creativity and good contingency planning.
