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.
that the required product quality level, consistency, effectiveness, and efficiency are realized, documented step-by-step processes, or standard operation procedures (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
