One of Edward De Bono's recent books, although, like the others, it re-works a lot of the same ideas, and he spends a lot of the book self publicising himself and his achievements with various organisations that use his methods. I must admit, l was glad when l had finally come to the end of it.
If you want to find out about the GG3 (Greek gang of three), using PO (provocative operation), The Six Hat techniques (black is judgemental etc), Opreacy (not literacy or numeracy, but getting things done), plus more, 'Think! Before It's Too Late' is the book for you, as they are all within.
"You can analyse the past, but you have to design the future". Yawn.
He's obviously a clever guy, and does try to think of new ways to do things, but a lot of the book was just boring and repetitive, with plenty of mentions of other books by him that you can also buy.
Good luck to him if he is making a fortune out of this stuff, but he certainly shouldn't be treated as some kind of all knowing guru and just slavishly followed, as some people do.
Then again, what do l know? l'm just a poor uneducated scumbag.
