SupplyChainBrain | SupplyChainBrainAnalyst Insight: Most products arrive in the hands of customers through traditional processes. Sales and operations build forecasts, make procurement plans, and order the necessary materials to produce the products, and manufacturing builds the products at the planned production rates. Distribution plans are established to account for some variation in demand, and customers are promised specific delivery dates. If all goes well, the gap between demand and supply at every point in the system will be small. But that rarely happens. –Eduardo Alvarez, principal, PwC, and Rodger Howell, principal, PwC March 8, 2017
