This book offers a concept to get meetings of 30 minutes instead of 4 hours. It’s about dividing thinking in six segments.

• white hat — We’ll only use information, facts (NOT feelings!) and truths and tackle the problem from an objective angle.
• red hat — This is when you can say: “I think this is rubbish”
• black hat — This is where we address the negative aspects.
• yellow hat — The other side of black, we get the positives out.
• green hat — Here we think towards creativity and new ideas
• blue hat — This is where we do not think about the problem but about the thinking we did! So did we miss something, what’s the structure we going to follow, etc…

Cons: There are a lot of example phrases which do not add much to the book.
