What they did and why it matters

Womack brought Toyota's methods to Western managers under the name lean, which is how most warehouses today learned about waste reduction, flow, and continuous improvement. His MIT team's study of global car factories coined 'lean production', and the follow-up book Lean Thinking, written with Daniel Jones in 1996, set out principles such as value streams, flow, and pull that apply beyond factories. Lean warehousing programs that map the path of an order, remove unnecessary touches, and level workloads across shifts draw directly on the vocabulary he popularized.
