James P. Womack writes business and operations books about lean production, manufacturing systems and the removal of waste from organisational processes. The Machine That Changed the World, written with Daniel Jones and Daniel Roos, compares mass production with the methods developed in the Japanese automotive industry. Lean Thinking, with Daniel Jones, turns those observations into principles for defining value, improving flow, reducing inventory and organising work around customer demand.

His work fits operations management, manufacturing, lean business and process improvement. Read more Less
