The document describes Edward de Bono's "Six Thinking Hats" method for structured thinking and discussion. The six hats represent six different perspectives or thinking styles: White Hat focuses on objective facts; Red Hat focuses on emotions and intuition; Black Hat focuses on caution and potential problems; Yellow Hat focuses on benefits and optimism; Green Hat focuses on creative ideas and possibilities; Blue Hat focuses on organization, process, and summary. The method can be used individually, in conversations, in meetings, and for reports to encourage comprehensive yet compartmentalized thinking from multiple perspectives.
