In "The Theory of Constraints and Its Implications for Management Accounting", the authors hail TOC's "Thinking Processes" as "...perhaps the most important intellectual achievement since calculus". The authors go on to comment on how these "Thinking Processes" are difficult to understand by most people.
With the release of "Thinking for a Change", Lisa has provided the "Thinking Processes" tools in a very accessible format. The everyday examples show us the power and the wide validity of these breakthrough problem solving tools. For veteran "Jonahs", the book provides tips on coaching others in the "Thinking Processes", and insight into the development of the tools that I've not found anywhere else.
For those with no introduction to the Theory of Constraints (TOC's) "Thinking Processes", they represent a paradigm shift in problem solving. A root cause analysis can be developed using the effect-cause-effect logic adopted from the scientific method. The old paradigm was if you don't understand something, collect more data. The new paradigm is that to understand something, you form effect-cause-effect logic and test it. The rules used to test the validity of the logic are presented in Lisa's book with everyday, yet compelling examples.
The validity of these "Thinking Processes" have been proven in application to organizational science, management science, as well as in the technical fields. The proof can be seen in the Profit and Loss statements of those companies who have adopted TOC as a overall management philosophy.
If you have found the writing of Senge, Wheatley, Covey, Gleich, and/or Pragiogini compelling, don't stop exploring until you have given TOC's "Thinking Processes", as outlined in Lisa's book a chance.

I recently finished reading the Thinking for a Change book and I am very impressed. I have now bought at least a half dozen copies and have started distributing them at work. This book is the most straightforward approach to actually beginning to apply the Thinking Processes that I have seen to date, and I have been doing a fair amount of reading on this over the past few months as my long term interest in TOC got revived six to eight months ago.
I have found this book and Thomas McMullen's book on the Theory of Constraints Management System to the be the best written of the latest crop of books to come out on this subject. Bill Dettmer's books provide much more detail, but Scheinkopf's stands out for its easy to follow examples and straightforward methodology.
I highly recommend this book to anyone interested in making more rapid progress toward their business or personal goals.

Just a quick note of thanks -- and congratulations -- for the great work that is "Thinking for a Change". (By the way, great title too!).
I am a recent Jonah, having completed the program in October at the Insititute. Your book takes a very different approach to teaching the TP and helped clear up alot of things.
Also, thanks for showing the way of a true helping Jonah by being so active on the net. You really live your beliefs and it is wonderful.
We too often take great effort and contributions for granted. I want you to know that yours is not (being taken for granted).
Sincerely, John Gaulin

I have been inrterested in Theory of Constraints for many years. However, I work in a world that is slow to change and did not offer the opportunity to openly apply this new theory. Recently the international corporation that I work for, asked me to undertake a study on one of our internal benefit programs. Three years running this problem was a major employee hot spot on the satisfaction survey. Despite numerous efforts the problems remained. As part of a working group I was asked to see what I could find out. I had just read Lisa's book and decided this was an ideal opportunity to do a complete Theory of Constraints approach on this issue. When I told senior management they were skeptical, but decided anything was worth a try. It was scheduled for a six months study. I said I would follow the processes in Lisa's book. Bottom line results: Lisa's book has processes that you can follow immediately after reading; the processes keep you on track; the problem was solved in three months. I have been asked to take the lead on another project that may benefit from Theory of Constraints processes. Unlike my old calculus classes the intuitively obvious steps are included and make this a must read.

Thinking for a change (T4aC) is an excellent review of the TOC Thinking Processes. It is written in easy to understand language and provides simple, straightforward examples of how, where and why to use the various TOC thinking tools. The big insight from this book is that it presents the tools out of the normal sequence and demonstrates how they are independently useful. This will help those new and familiar with TOC to better understand the specific roles of the various tools and how they fit together.
Ms. Scheinkopf also provides very nice step-by-step guidelines for using each of the tools. While no one will ever become a Jonah by reading a book, this one sets the reader up for success by explaining the basics and providing examples that show how using TOC is a natural process and can be used in daily tasks and relationships.

This is the TOC book that I lend to my friends when I want to explain TOC. Eli Goldratt's books are good for the spirit of TOC, but when I want to explain how to actually use the Thinking Processes, this is the best book for that purpose. The Dettmer book is also a good explanation of TOC, but "Thinking for a Change"'s use of everday situations makes a better case for using TOC in your daily life.
