I found his book Water Logic intriguing. It encouraged setting out problems as a series of nodes, or factors in the problem, which you'd then connect with one-way arrows. So, this affects that, and that affects the other. The idea was that you'd end up with a sort of flow chart where some nodes/factors had multiple arrows pointing at them - and these were blocking points. A surprisingly useful tool on some occasions; certainly helped discussions about dependencies etc. But it must have been a minor work because I can't find anything worthwhile online atm about it. For me, though, de Bono's best contribution to my life was the L game. I still play it. https://en.wikipedia.org/wiki/L_game https://en.wikipedia.org/wiki/L_game
