Which of the following is a key benefit of using POS, loyalty, and market data...

The correct answer is D .

POS, loyalty, and market data improve supply-chain planning because they give the organization a clearer picture of real shopper demand, product movement, and market behavior. CMKG connects supply chain directly to forecasting and availability, which are exactly the areas improved by better demand signals. In retail and CPG, sharing checkout and shopper-purchase data is commonly used to improve demand forecasting and avoid out-of-stock situations.

Option A is wrong because better data does not remove the need to monitor KPIs; it makes KPI monitoring more accurate. Option B is wrong because data usually increases the need for retailer-supplier collaboration. Option C is unrealistic because no data system can guarantee every SKU is always in stock. Option D is the correct practical benefit: better forecasting and fewer stockouts.
