Dr Eli Goldratt is the originator of the Theory of Constraints (TOC). His first book, The Goal, remains to be a bestseller for more than 20 years after its inaugural publication. Dr. Goldratt was an educator, author, scientist, philosopher and business leader but he was, first and foremost, a thinker who provokes others to think. Often characterized as unconventional, stimulating, and "a slayer of sacred cows". Dr Goldratt had exhorted his audience to examine and reassess their business practices with a different perspective and new vision.
Every business has at least one constraint (or leverage point) which limits the output of the entire business operation – Constraint limits business profitability – just as chain’s weakest link limits its strength.
Theory of Constraints (TOC) is systematic management approach which focuses on improving a few physical and logical leverage (constraints) points of an organization in order to achieve an order of magnitude improvement in the performance of the system as a whole. TOC is mainly about focus – focusing your efforts in the right place to achieve maximum benefit.
Dr. Eliyahu Goldratt first introduced TOC through his book "The Goal". Even after 25 years of its release, The Goal is still considered a classic must-read, common-sense manual for people at all levels in companies worldwide. Dr. Goldratt's subsequent books mark the major phases of TOC's evolution, expanding its scope and application to inbound supply chain, production/operation, outbound supply chain, new product development, marketing & sales, distribution & retail management, finance & measures etc.
