De Bono's Thinking Hats

The BLUE Hat	The process hat - what process should we use to discuss this? What order shall we use the hats? (There might be several cycles where you keep coming back to particular hats.) How is the process going? Is everyone happy with the process? Should we change it?
The WHITE Hat	The information hat - what information do we have? What information do we need? What information is missing? How are we going to get the information? What questions should we be asking? What is the context of this? What is it connected to?
The YELLOW Hat	The optimistic hat - what is good about this? What are the benefits? Who is going to benefit? How will the benefits come about? What are our underpinning values we are applying when judging the benefits? What are other possible value systems that could be used to give new insights?
The BLACK Hat	The cautious hat - what are the negatives here? What are the obstacles? Who and what is going to be affected? Look at both the big picture and the particular. What are the risks? What might stop this from working? What are the costs? What hasn‘t been thought about?
The RED Hat	The feeling hat - How are we each feeling about this now? What are our gut feelings, intuition or instincts? (no need to justify them with logic)
The GREEN Hat	The creative hat - What are possibilities, new ideas and alternatives? How can we overcome obstacles? How can we create new solutions and new benefits? How can we modify, adapt, combine, synthesise, maximise, or minimise old ideas into new possibilities? What haven‘t we thought about that might have positive effects?
JOKER Hat	Make up your own hat for the group to wear when you feel things could be discussed in new ways not covered by the above hats. (eg come up with a random word)
