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.

and customer orders. Thus, MRP creates plans to push materials through the production process based on forecasts that by nature cannot be accurate. That is to say, traditional MRP methods rely on the movement of materials through functionally-oriented work centers or production lines (rather than lean cells), and are designed to maximize efficiencies and lower unit cost by producing products in large lots. Production is planned, scheduled, and managed to meet a combination of actual and forecast
