Book Description

October 2000
After reading the newspapers and following the sharp oscillations of the stock market, it becomes apparent that hi-tech companies are of a different breed. Never before have the chances of making a fortune been so realistic and never before have large companies been so fragile. What is really going on inside these hi-tech companies? What types of pressures and challenges are they facing? And how do they cope?

Computer software providers, especially the ones that specialize in handling the data needs of organizations, are prime examples of these volatile companies. In the nineties we witnessed their growth from small businesses into multi-billion dollar giants. No wonder investors were attracted.

In 1998 it was easy for such companies to raise as much money as they wanted. But now, investment funds have dried up. Why? And more importantly, is there a way to reverse the trend? This book gives the answers.

2.0 out of 5 stars Who forgot to proof-read?, January 4, 2001
By A Customer
This review is from: Necessary But Not Sufficient (Paperback)
I bought this book after reading The Goal, and It's Not Luck. I found The Goal and It's Not Luck to be very interesting to read. This one left a lot to be desired.

Some of Goldratt's assumptions in Necessary But Not Sufficient seem to be overly simplistic. For instance, he seems to advocate stripping out of mid-market ERP systems everything but production & inventory control. I doubt that too many manufacturing companies would really be beating down the doors of any ERP company who actually did this. He also seems to think that major changes can be made to an ERP system in a couple of weeks. Anyone who has dealt with changes to any software system, no matter how simple the system or how simple the change, knows that is simply not true.

I would like to see some case studies published to back up Goldratt's stories. In all of his books that I have read I have found his implementation successes a bit hard to swallow. I like his theories, but I think that actual case studies would greatly increase his credibility, especially with this book.

But my biggest gripe about this book is this: Who proof-read this thing? I have never read a book with so many typos! I would think that with 3 authors on the cover and a publishing company behind them that at least somebody would have read the thing first! It really got to be annoying to read through all the errors.

Anyways, read The Goal and It's Not Luck and skip this one.

2.0 out of 5 stars Not even necessary!, April 5, 2001
This review is from: Necessary But Not Sufficient (Paperback)
Anxiously awaited, and extremely disappointing work from the authors. Reasons:

A. Inferior content. Neither does the book present a sound theory of enterprise/ B2B software, nor does it do do justice to the intellect and experience of its authors.

For example, why should "Drum Buffer Rope" software be part of the larger enterprise system? Or why companies need enterprise software in the first place? Just because the technologies are there?

Potential readers looking for ground-breaking thoughts in enterprise management and enterprise software are advised to read following previous works by two of the book's authors: 1. "The Haystack Syndrome" by Dr. Eli Goldratt 2. "Management Dilemmas" by Eli Schragenheim

B. Defeats the purpose. Enterprise software users, enterprise software providers and management consultants all risk being led down the wrong path by following superficial advice contained in the book.

For example, isn't it impractical to ask outsiders (enterprise software providers) to ensure that the insiders (enterprise managers) create value for their organizations? Does it mean that management also can be outsourced?

C. Amateurish storyline and poor editing. At a minimum readers should not be denied the pleasure of good reading!

The only value rendered by this book is reminding managers that all their investments, even in software, should have measurable payoff.

2.0 out of 5 stars 99% Novel, 1% TOC, May 17, 2005
This review is from: Necessary But Not Sufficient (Paperback)
Necessary But Not Sufficient can be boiled down to three points:

1. Technology is worthless if it doesn't bring bottom-line value.
2. "Drum-buffer-rope" and "Buffer Management" are good
3. "Pull" inventory management is good

As an rabid reader and huge fan of The Goal, I was dissapointed with the delivery of this book. The fictional plot was boring and the characters were met with absolute apathy. While the above three points are repeated ad nauseum, no real background or detail is revealed on their delivery or use. Instead, Necessary But Not Sufficient is written as lengthy pieces of plot followed by short, almost textbook definitions of these business concepts.

If you're looking for a more interesting and in-depth read, stick with The Goal. Otherwise, shop around for a more engaging and insightful book.
