Book Description:

“The chief cause of problems is solutions.”- Eric Sevareid”Every situation, no matter how complex it initially looks, is exceedingly simple.”- Eli Goldratt In 2018 I attended a training course in Paris that fundamentally changed my perspective. This was H. William (Bill) Dettmer’s six-day course in the Logical Thinking Process, an exceptionally powerful methodology for strategy definition and problem solving, based on the methods of Dr. Eli Goldratt, author of The Goal and systems management legend, adapted and refined by Bill Dettmer.Towards the end of the course I realized how mastering this rigorous methodology changes the way you approach situations of any kind. It helps you deal with difficult situations in a way few if any other methodologies can.Achieve breakthrough results by deciphering complex causality, unearthing false assumptions and removing the conflicts caused by faulty mental models; this is what the Logical Thinking Process helps us to do, using classical cause-effect logic. In this book, a simple, everyday example is used to demonstrate how to apply the Logical Thinking Process and how it helps us drive success by making sounder, more rational decisions. The book also contains practical organizational examples and a concise overview of the framework.

Reviews for the Book

I love this little book! It's a quick read packed with value.
Using this book (with a bit of help from Clark Chinge's short book "Rolling Rocks Downhill" because I was so new to this way of thinking) I was able to uncover a wicked conflict whose solution had baffled me for decades. Once I understood it, I was finally able to take action to address it.
This book is wonderfully clear, even to someone new to Logical Thinking Process and Theory of Constraints as I was. Diagramming problems and potential solutions in stages -- which this book walks you through -- lets you spot problems and develop solutions using the power of visual thinking. Diagrams activate pattern-recognition parts of your brain that no amount of talking and abstractions can get to. So this is a very powerful method of solving problems, and Thorsteinn Siglaugsson has done a great job of making it accessible. Highly recommended! -	Joy Livingwell
