Goldratt presents his thought provoking approach, this time through a conversation with his daughter Efrat, as he explains to her his fundamental system of beliefs. The revised edition includes Efrat's own notes and maps (charts) she made during her conversations with her father, helping the reader determine the true essence of the book.

From the original publication:

TOC has been successfully applied in almost every area of human endeavor, from industry to healthcare to education. And while Eli Goldratt is indeed a scientist, an educator and a business leader, he is first and foremost a philosopher; some say a genius.

He is a thinker who provokes others to do the same. Often characterized as unconventional, and always stimulating a slayer of sacred cows Dr. Goldratt exhorts his readers to examine and reassess their lives and business practices by cultivating a different perspective and a clear new vision.
