What is the key design element of a cost-to-serve model?

• A. Maps activities by customer or product, assigns costs, calculates unit costs, identifies cost drivers and potential savings.
• B. Forecasts overall industry growth for pricing strategy.
• C. Uses standard costing by department with no activity detail.
• D. Focuses on revenue forecasting rather than costs.

Answer: (A)

The key design element is to break down costs by the actual activities that serve each customer or product. This means mapping the work involved across the full service and fulfillment process, assigning the costs to those activities, and then calculating unit costs for each customer or product based on how much of each activity they use. From there, you identify the cost drivers—the specific actions or resources that most influence cost—and uncover where potential savings or efficiency improvements can be found. This activity-based approach gives a clear view of why some customers or products are more expensive to serve and how pricing, service levels, or process changes could improve profitability. Other options miss the essential focus on activity-level cost allocation. Forecasting industry growth is about market trends, not the cost to serve a particular customer or product. Using standard costing by department with no activity detail ignores how different activities drive costs. Emphasizing revenue forecasting rather than costs shifts the lens away from how resources are consumed to how revenue is expected to grow, which doesn’t diagnose the true cost structure of serving customers.
