This document describes Edward de Bono's 6 Thinking Hats technique for structured group discussion and decision making. The technique involves metaphorically "wearing" one of six colored hats at a time, with each hat representing a perspective or way of thinking. The six hats are white (facts), red (emotions), black (caution), yellow (optimism), green (creativity), and blue (process of thinking itself). By considering an issue from the viewpoint of only one hat at a time, it aims to encourage comprehensive yet impartial thinking.
