Dr. Eliyahu M. Goldratt

Dr Eliyahu "Eli" Goldratt (1947 - 2011) was an Israeli physicist turned management guru. He created the management idea called the Theory of Constraints which has since been proven in thousands of companies, industries and geographies. He was the author of the best-selling business novel 'The Goal' and many other works that have been almost as influential including 'Critical Chain' which revolutionised how we manage projects, 'Necessary But Not Sufficient' on how we use and obtain value from technology, 'Isn't It Obvious', called 'The Goal' for Retail and many others. Eli was the originator of Goldratt Research Labs and now is the inspiration behind Harmony Applied Insight
