James Womack and Dan Jones are the founders of the Lean Enterprise Institute and the Lean Enterprise Academy (UK), respectively. Their book, Lean Thinking: Banish Waste and Create Wealth in Your Corporation, is considered by some to be the bible of Lean manufacturing. It was originally published in 1996 based on their in-depth study of Toyota’s fabled Toyota Production System (TPS). Philip Caldwell, Chairman and CEO of Ford from 1980-1985, said of the book, “Truly remarkable...The most comprehensive, instructive, mind-stretching and provocative analysis of any major industry I have ever known.”
Lean Thinking lays out the five Lean manufacturing principles: value, value streams, flow, pull, and perfection. Here’s some insight into what Womack and Jones meant by each.
