Six Thinking Hats

Blurb

Six Thinking Hats is a self-help book by Edward de Bono which describes a tool for group discussion and individual thinking involving six colored hats. "Six Thinking Hats" and the associated idea parallel thinking provide a means for groups to plan thinking processes in a detailed and cohesive way, and in doing so to think together more effectively.
In 2005, the tool found some use in the United Kingdom innovation sector, where it was offered by some facilitation companies and had been trialled within the United Kingdom's civil service.
