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.

no defective items reach downstream processes. For example, in an assembly operation, if each correct part is not used, a sensing device detects that a part was unused and shuts down the operation, thereby preventing the assembler from moving the incomplete part to the next station or beginning another operation. Total Productive Maintenance Lean manufacturing further requires manufacturers to address equipment productivity issues through the adoption of total productive maintenance ( TPM ), which is a
