A number of lean manufacturing tools and practices have long been used to reduce manufacturing waste. These include the five S's, visual controls, standardized work, mistake proofing, total productive maintenance, cellular manufacturing, single-digit setup, pull systems, sequencing, activity-based costing, and leveled production.
the single-minute exchange of die ( SMED ) concept of setup times of less than ten minutes, which was developed by Shigeo Shingo in 1970 at Toyota. Pull System A pull system is another key characteristic of lean, demand-driven manufacturing, since the ultimate goal here is to have the flow of materials controlled by replacing only what has been actually consumed. Pull systems, also known as kanban (coming from the Japanese words kan , which means card , and ban which means signal ), ensure that producti
