The Theory of Constraints...

“The Theory of Constraints (TOC) is a philosophy of management and improvement originally developed by Eliyahu M. Goldratt and introduced in his book, The Goal. It is based on the fact that, like a chain with its weakest link, in any complex system at any point in time, there is most often only one aspect of that system that is limiting its ability to achieve more of its goal. For that system to attain any significant improvement, that constraint must be identified and the whole system must be managed with it in mind.”
