A retailer rejected a $2 million material-handling investment because its ROI considered only labor savings. Yet reducing dock-to-stock time from 96 to 24 hours could eliminate $6 million in inventory and significantly lower carrying costs. The case shows why supply chain investments must be evaluated holistically, capturing inventory, capital, service, and productivity benefits.

Choosing supply chain software should not default to ERP or best-of-breed solutions. The right approach minimizes vendors, applications, and interfaces while meeting functionality, ROI, and implementation requirements. ERP may work for simpler operations, while complex, mission-critical supply chains may require specialized solutions. The best technology is the one that fits the business’s actual needs.

Reducing inventory and lowering unit costs can create conflicting decisions, since global sourcing and volume discounts often increase inventory. Instead of optimizing individual metrics, supply chain leaders should focus on broader outcomes such as ROIC, perfect order performance, and total supply chain cost. Inventory should be treated as a strategic means to achieve business objectives—not as an end in itself.
