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.

manufacturing customarily tends to focus on the replenishment and supply of commodity parts (i.e., parts that are shipped in standard packs by the dozen or as case lots), while JIT sequencing concentrates on unique (or configured) parts, which are shipped individually or shipped with other configured parts of the same kind.
