The DBA Demand Driven Planning System
Demand driven planning removes tentative demand from your action plan and uses strategic stocking of critical items to reduce lead times and time to shipment. Any type of business can succeed by focusing on three basic MRP settings: lead days for your purchased items, job days for your manufactured items, and a clear cut order policy based on lead day contribution. Companies that embrace the DBA demand driven planning can see dramatic improvements in their inventory efficiency and shop throughput.
