Summary: Necessary But Not Sufficient - definitely
Review: I'm sold on the whole TOC concept, after all: it's the application of logical thinking.Working in the IT industry, I think this is totally applicable. I am convinced if enough managers read this, it will make a huge difference and give our company an enormous edge.

Summary: Not Sufficient
Review: If you don't know what Drum-Buffer-Rope is before you read this book you still won't afterword. I can't believe how many times this is mentioned without an explanation. And it is not much better for Buffer-Management. There is no real substance here.

Summary: Equal to The Goal
Review: If you're wondering why you didn't get a powerful return on your new ERP system, read this. Just as Eli's first book, The Goal, explained why manufacturing (in the '80's) was doing so poorly, Eli and his co-authors provide an equally lucid look at why ERP systems so seldom produce the return the vendors promise. Written in a story form, it identifies the problems faced by ERP system companies, systems integrators, and of course, their clients, the manufacturing companies. There are also glimpses of what makes advanced planning and scheduling important, an interesting way of developing a pull-based supply chain, and a VERY interesting perspective on getting supply chain partners to collaborate. The book is not meant as an exhastive reference, but only a means to get you to think. It succeeds. I would have given it 5 stars, but there are too many typos, and I think they could have gone more deeply into many of the subjects they brushed over. It would have been more satisfying to have a little more depth at the expense of breadth.

Summary: One of Goldratt's two best books!
Review: If, like me, you spent the 90's in the Advanced Planning and Scheduling (APS) industry then you will likely share my opinion that "Necessary But Not Sufficient" is one of Goldratt's two best books. If you work at a manufacturing company, and you are wondering why you got little more from your Enterprise Resource Planning (ERP) software implementation than Y2K compliance, this book will give you some valuable insights. If you work at an ERP company, this book is a must read.

Summary: Finally finished Necessary But Not Sufficient
Review: In my opinion Necessary But Not Sufficient failed to meet the Goldratt five star standard in holding ones interest and unleashing the readers innovative juices. This book lacked an engaging quality found in The Goal, It's Not Luck, and Critical Chain. I felt detached from the story rather than part of the story.
I found the book tedious and more often than not, boring.

Summary: When is something going to happen?
Review: Let me first start by stating that I am a big Goldratt and Theory of Constraints fan, but this book was bad. Over ¾ of the book is a statement of the problem and then a solution is proposed that is so high level it is impossible to learn anything applicable from it and I'm a Jonah. Also, the book needs some major editing.

Summary: People Rule
Review: Technology is great, however in and of itself it does not solve anything, and often compounds the problems which it is deployed to fix. Goldratt discusses this issue extensively in "Necessary but Not Sufficient" BGSoft is a fictional ERP company that must face the reality of the aforementioned dilemma. BGSoft's clients desire a measurable ROI following the massive expenditure required for an ERP installation. This ERP vendor must dig deep to document the tangible bottom line (financial) benefits, which its clients reap from installation of the software. In his typical business novel format, Goldratt masterfully engages the reader, and eloquently presents the logic used to bring about bottom line results. The results achieved are impressive, and involve the application of the Theory of Constraints. The company must carefully craft its moves so as to appease Wall Street. Goldratt also delves into the reasoning behind the sometimes-astronomical valuations of technology companies, and the massive fluctuations associated with this speculative sector. "Necessary but Not Sufficient" provides rock solid logic that is fundamental for success in today's technology focused business environment. While the focus here was an ERP vendor and it's clients, the same fundamentals apply equally well to the dot-com world. Look at the big picture, find the constraint, elevate it, and repeat. Most of all remember that people solve problems and bring about change and improvement. Technology is merely a tool, often necessary, but not sufficient in and of itself.

Summary: Worst of the TOC Novels
Review: This book has very little new material from previous TOC books. It doesn't lead the reader as well as The Goal or It's Not Luck. In short it is a "Rah-Rah" book telling the reader how great TOC is without giving much detail and in the context of a novel that doesn't create a great amount of character sympathy. I really don't understand how a man as brilliant as Goldratt could have written this. Get The Goal, It's Not Luck, and the appropriate textbook(s) to implement TOC in your business.
