Book excerpt: The Creating Level Pull workbook shows you how to advance a lean transformation from a focus on isolated improvements to improving the entire plantwide production system by implementing a lean production control system. "The workbook is unique because it is a step-by-step case study on how to implement a level, pull-based production control system," said author Art Smalley. This is a new step towards 'system kaizen that is not yet well understood outside of Toyota.The lean efforts at most companies focus on "point kaizen" (e.g., reducing set up times, implementing 5S, etc.) that improves a small portion of the value stream running from raw materials to finished products. Or they focus on "flow kaizen" that improves the entire value stream for one product family. Creating Level Pull shows how companies can make the leap to "system kaizen" by introducing a lean production control system that ties together the flows of information and materials supporting every product family in a facility. With this system in place, each production activity requests precisely the materials it needs from the previous activity and demand from the customer is levelled to smooth production activities throughout the plant.[Source : 4e de couv.].
