The Demand to Management Oracle Manufacturing Business Process (OMBP) in Oracle Fusion Cloud SCM focuses on translating demand signals into actionable supply plans, making Forecast Accuracy the key metric for measuring its effectiveness. Forecast Accuracy compares predicted demand to actual demand, revealing how well the system anticipates customer needs. For instance, if a forecast predicts 1,000 units sold but actual sales are 900, the accuracy is 90%, highlighting areas for improvement. Option A (Employee Turnover Rate) is an HR metric unrelated to demand management. Option C (Customer Acquisition Cost) pertains to marketing, not supply chain processes. Option D (Order Fill Rate) measures fulfillment efficiency, which is a downstream outcome, not a direct indicator of demand forecasting effectiveness. High forecast accuracy ensures inventory aligns with demand, reducing overstock or shortages, and supports strategic decision-making across procurement and production.
