This is certainly one of the great books on TOC (Theory of Constraints) and drives home the fact that TOC on it's own is often not enough to get quantum leaps in throughput.
Written in a similar style to "The Goal" and "It's Not Luck" (both of which I'd suggest you read before this book) you're taken in to the world of an ERP software company and their biggest systems integration company. Seemingly insurmountable challenges and certain doom face the teams as their core market becomes saturated - can TOC come to the rescue once again? Yes, of course, but to achieve full potential it needs a helping hand from a few other things... You'll have to read the book to find out :)
I deducted one star because once again we find retail supply chain management starting to dominate towards the end of the book and our company has nothing to do with, and does not come in to contact with, that area of business. I'm hoping that Goldratt will release a TOC book that doesn't mention, or even allude to, retail supply chain management.
