Alex Rogo is a harried plant manager who has been given 90 days to save his failing factory. If he doesn’t improve the plant’s performance, corporate headquarters will close it down and hundreds of workers will lose their jobs. It takes a chance meeting with Jonah, a former professor, to help him break out of his conventional thinking and figure out what needs to be done. As Alex identifies the plant’s problems and works with his team to find solutions, the reader gains an understanding of the fundamental concepts behind the Theory of Constraints.
