This document provides an introduction to the Six Thinking Hats framework developed by Edward de Bono. The Six Hats include White (facts), Yellow (optimism), Black (caution), Green (creativity), Red (intuition), and Blue (process control). Each hat represents a different thinking perspective or role. The framework is intended to separate types of thinking, avoid groupthink, promote parallel thinking, and structure conversations and decision making. The document outlines the purpose and use of each hat, provides examples, and discusses considerations for effective versus ineffective implementation of the Six Hats approach.
