Within CPFR, a significant difference between forecasts produced by collaborating parties is treated as an exception . Exception management is fundamental to collaborative planning because the purpose of CPFR is not merely to exchange forecasts; it is to identify material differences, investigate their causes, and reach a coordinated planning position.
For example, a retailer may forecast demand of 20,000 units based on promotions and point-of-sale expectations while a supplier forecasts 14,000 units based on previous demand patterns. If the difference exceeds an agreed tolerance, the system flags the variance as an exception. The organizations can then determine whether the discrepancy results from a promotion, assortment change, inventory condition, market event, capacity limitation, or incorrect underlying assumptions.
The same exception-management principle may apply when other performance indicators fall outside established bounds, such as excessive inventory, inadequate product availability, or abnormal replenishment requirements. This focuses management attention on meaningful deviations rather than requiring planners to manually review every SKU and forecast.
Although “discrepancy” and “mismatch” describe the situation in ordinary language, exception is the specific CPFR terminology.
Therefore, D is correct.
