Dr. Eliyahu M. Goldratt was an educator, author, scientist, philosopher, and business leader. But he was, first and foremost, a thinker who provoked others to think. Often characterized as unconventional, stimulating, and “a slayer of sacred cows,” Dr. Goldratt challenged management teams to examine and reassess their business practices with a fresh, new vision.
Dr. Goldratt created and developed the Theory of Constraints (TOC), an overall framework for helping organizations and individuals to determine:
Dr. Goldratt was an internationally recognized leader in the development of new business management philosophies and systems. He was a sought-after educator by many of the world’s largest corporations, including General Motors, Procter & Gamble, AT&T, NV Philips, ABB and Boeing. He obtained his Bachelor of Science degree from Tel Aviv University and his Masters of Science, and Doctorate of Philosophy from Bar-Ilan University. In addition to his pioneering work in business Management and education, he held patents in a number of areas ranging from medical devices to drip irrigation to temperature sensors.
Dr. Eliyahu M. Goldratt was the founder of TOC for Education, a non-profit organization dedicated to bringing TOC ideals to teachers. After retiring from the Avraham Y. Goldratt Institute in the mid 90s, he founded Goldratt’s Marketing Group to make the TOC knowledge available to the market in the form of self-learning resources, Goldratt Consulting to bring companies to being ever-flourishing, and Goldratt Schools to teach and train individuals seeking to expand their TOC knowledge — the Goldratt Group was created. He asked Dr. Alan Barnard to create Goldratt Research Labs as an independent company, spearheading the development of new knowledge and applications of TOC through research partnerships.
The TOC concepts were first illustrated in his best-selling book “THE GOAL”, a non-traditional approach to convey knowledge — it is a business textbook written in novel form, disguised as a love story. The books that followed were “THE RACE”, “WHAT IS THIS THING CALLED TOC?”, “THE HAYSTACK SYNDROME”, ”PRODUCTION THE TOC WAY”, “IT’S NOT LUCK”, “CRITICAL CHAIN”, “NECESSARY BUT NOT SUFFICIENT”, “ISN’T IT OBVIOUS”, and “THE CHOICE”. He was a frequent contributor to scientific journals, magazines and business publications and sat on several editorial boards.
