The document discusses the process by which marketing, costing, procurement, production planning, and logistics departments collaborate to estimate and track costs for a manufacturing product. The marketing department obtains a purchase order from a customer. The costing department takes the purchase order cost and subtracts profit and overhead to determine the manufacturing cost, which is divided into procurement, machining hours, assembly hours, and packing/transportation costs. The procurement, planning, and logistics departments provide cost estimates to the costing department for these elements, which are tracked against actual costs achieved. Differences between planned and achieved costs are monitored to identify opportunities for cost reduction.
