Theory of Constraints (TOC)

The Theory of Constraints (TOC) is a philosophy of management and continuous improvement originally developed by Dr. Eliyahu M. Goldratt and introduced in a book called The Goal. The book, a novel, is often used in business classes. The story, which is told in first person narrative, is about a new plant manager who is given ninety days to turn things around and make the plant run successfully or the plant will close. The plant manager finds a mentor who asks questions that guide the manager -- and the reader -- to realize that every complex system has at least one constraint (bottleneck) and it's the constraint that determines the ability of the system to be successful.
