- The Six Thinking Hats technique was developed by Dr. Edward de Bono to provide a methodical approach to group decision making. It involves wearing metaphorical "hats" that represent different perspectives or modes of thinking. - There are six colored hats - blue, green, white, yellow, red, and black - with each hat representing a different way of thinking. Participants discuss an issue while collectively "wearing" one hat at a time to structure the thinking process. - Case studies show the technique has helped large organizations like NASA, IBM and Shell improve decision making and problem solving. It allows parallel thinking and prevents arguments that can stall progress.
