The document discusses Edward de Bono's Six Thinking Hats technique for parallel and effective problem solving. The technique involves assigning six colored hats to represent six types of thinking: white for objective facts, red for emotions, black for caution, yellow for optimism, green for creativity, and blue for organization and control. A group addresses a problem or project by having structured discussions during which members must only consider the aspect of thinking represented by the hat they are "wearing" at that time. This allows the group to explore issues from different perspectives in an orderly manner to arrive at well-rounded solutions. The document provides details on how the technique can be applied to define problems, generate and evaluate ideas, and develop implementation strategies.
