This document discusses Edward De Bono's 6 Thinking Hats method for group discussions. It provides examples of how each "hat" or perspective could be applied when considering opening a new restaurant: the White Hat focuses on objective facts, the Yellow Hat on optimism, the Green Hat on creative ideas, the Black Hat on criticism, the Red Hat on emotions, and the Blue Hat on process and agenda. The document encourages using a maximum of 2 hats per person during a discussion and avoiding overuse of the Black Hat. It also provides guidance on using this technique for a workshop on evaluating concepts.
