The Push-based metrics of the past worked well—until manufacturers had to react rapidly to new and emerging customer demands. Demand-driven factories change virtually all their metrics because previous measures were based on local efficiencies and push philosophies, not pull-based, demand-driven methods focused on actual customer orders. When a manufacturer synchronizes its processes to visibly follow the customer demand signal through the supply chain, the metrics change—for the benefit of the customer. Demand-Driven Manufacturing Metrics that Drive Action addresses the key elements of demand, or pull-based manufacturing: Managing constraints and synchronizing activities to improve production flow and, ultimately, throughput.
