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.

(SOP), are needed to define the standardized work necessary to reduce errors and touch times. Standardized work is one of the most overlooked tools of lean manufacturing, despite entailing the useful creation and documentation of clearly defined operations for both workers and machines. Such clearly defined operations allow manufacturers to apply best practices to manufacturing processes. Standardized work also provides the foundation for continuous improvement, since documented processes can be more
