Laconically more value with less work. Lean manufacturing is a manufacturing philosophy that shortens the time between the customer order and the product build or shipment by eliminating sources of waste. Another way of looking at lean is that it aims to achieve the same output with less input-less time, less space, less human effort, less machinery, less material, less costs. Japanese manufacturers’ re-building after the Second World War was facing declining human, material and financial resources. The problems they faced in manufacturing were vastly different from their Western counterparts. These circumstances led to the development of new and lower cost manufacturing practices. Early Japanese leaders such as the Toyota Motor Company’s Eiji Toyoda, Taiichi Ohno and Shigeo Shingo developed a disciplined, process-focused production system now known as the “Toyota Production System”, or “Lean Production”. The objective of this system was to minimize the consumption of resources that added no value to a product. When a U.S. equipment manufacturing company, Lantech completed the implementation of lean in 1995, they reported the following improvements compared to their batch-based system in 1991; manufacturing space per machine was reduced by 45%, defects were reduced by 90%, production cycle time was reduced from 16 weeks to 14 hours-5 days and product delivery lead time was reduced from 4-20 weeks to 1-4 weeks.
