The document introduces Edward de Bono's Thinking Hats method for structured thinking and problem solving. The method uses colored hats to signify different perspectives or types of thinking - the white hat focuses on objective facts, the green hat encourages creative ideas, the black hat looks at risks and negatives, the yellow hat considers benefits, the red hat expresses feelings, and the blue hat manages the thinking process. Using different colored hats helps produce critical thinking, collaboration, communication and creativity by allowing people to consider an issue from different angles before coming to a conclusion.
