amazon review: Thinking for a Change / Lisa Scheinkopf

			Thinking for a Change: Putting the TOC Thinking Processes to Use (The CRC Press Series on Constraints Management) by Lisa J. Scheinkopf Edition: Hardcover
user friendly Thinking Process, September 14, 2014 This review is from: Thinking for a Change: Putting the TOC Thinking Processes to Use (The CRC Press Series on Constraints Management) (Hardcover) Every improvement is a change. But every change is not an improvement. Main message of The Goal: Clarify the organization's purpose.. These ideas bringing us to 3 major questions: 1. What to change ? Sufficiency based Current Reality Tree and Necessity based Evaporating Cloud to find the root cause 2. To what to change ? Sufficiency based Future Reality Tree 3. How to cause to change ? Sufficiency based Transition Tree (almost know what to do) Necessity based Prerequisite Tree (no idea how to achieve objective) These are the foundations of Thinking Process (TP). These are the tools helping us to locate the constraint. Next step is dealing with the constraint by 5 Focusing steps of TOC. 1. Identify the constraint 2. Exploit the constraint 3. Subordinate everything else to the constraint 4. Elevate the constraint 5. Beware of inertia, go back to Step 1. Sufficiency : to say that "Y" is an effect of "X" is to say the following: If X then we must have Y. Y exists because X exists. Necessity : to say that "B" is a necessary condition for "A" is to say the following: In order to have A, we must have B. We cannot have A unless B is in place. The book is really user friendly. I have understood Legitimate Reservations are not only control methods but also helipng to construct the tree. It is well explained when to use which techniques or do we really need them. Basic notions and drawing/phrasing guides are stated. There are some examples in the book.  I think this book alone is not enough to try TP on your own. I will keep reading relavant literature.
