The Goal: A Process of Ongoing Improvement

Fiction, about a guy who runs a failing factory, and via as series of dialogues with a mysterious mentor and his team, figures out how to transform it into the star plant in the division. I was a bit sceptical about the story format, but it really works - an entertaining and yet highly educational and elightening introduction to Theory of Constraints (TOC) - basically all about identifying and attacking bottlenecks in your production process. Superb.
