In their landmark book The Machine That Changed the World, James Womack and Daniel Jones, two of the top industrial analysts is the world, explained how companies can dramatically improve their performance through the "lean production" approach pioneered by Toyota. Lean Thinking extends these ideas to provide a rallying cry for today's corporate leaders.

After a decade of downsizing and reengineering, most companies in North America, Europe, and Japan are still stuck, searching for a formula for sustainable growth and success. The problem, as Womack and Jones explain in Lean Thinking, is that managers have lost sight of value for the customer and how to create it. What's needed is "lean thinking" -- a groundbreaking new mindset that is revolutionizing the way of the modern business world.

Using case studies of "lean" companies around the world who have energetically embraced leanness in pursuit of their own perfect enterprises, Womack and Jones explain this exciting new concept in fascinating detail.

Clearly demonstrating the simple ideas behind lean thinking that can breathe new life into any company in any industry. Lean Thinking offers a new way of thinking, being, and doing for the serious manager -- one that will change the world.

The core of the lean model remains the same in the new edition. All businesses must define the "value" that they produce as the product that best suits customer needs. The leaders must then identify and clarify the "value stream," the nexus of actions to bring the product through problems solving, information management, and physical transformation tasks. Next, "lean enterprise" lines up suppliers with this value stream. "Flow" traces the product across departments. "Pull" then activates the flow as the business re-orients towards the pull of the customer's needs. Finally, with the company reengineered towards its core value in a flow process, the business re-orients towards "perfection," rooting out all the remaining muda (Japanese for "waste") in the system.

Despite the authors' claims to "actionable principles for creating lasting value in any business during any business conditions," the lean model is not demonstrated with broad applications in the service or retail industries. But those manager's whose needs resonate with those described in the Lean Thinking case studies will find a host of practical guidelines for streamlining their processes and achieving manufacturing efficiencies. --Patrick O'Kelley
