A long time ago, in a galaxy that bore a distinct resemblance to the Milky Way, I co-authored a book on business creativity called Imagination Engineering . It did quite well and it still sells today. This was when my colleague Paul Birch and I were first setting up giving training in creativity, and the main purpose of the book was to be the guide to our method. It described our approach to stimulating ideas and solving problems. Something we thought that might be useful was to give some sort of simile or metaphor that would help us to describe and encourage the process of producing an enhancing ideas. We wanted it to be something that was all about pioneering, about boldly going and all that kind of thing. So we hit on the simile of civil engineering, saying our approach to creativity was like being the first to build roads and railways and structures out in a new and unexplored land. To be honest, we don't use the simile anymore, as it got in the way more than it helped....
