Dr. Frazelle explains that the goal of supply chains is not to minimize inventory, but to optimize inventory. In inventory optimization the answer is often to increase inventory levels to improve business and supply chain performance. The inventory strategy need to define when and why is it optimal to increase or reduce inventory levels.

The article explains that the growing gap between supply chain complexity and decision-making capabilities drives higher costs, excess inventory, and inefficiencies. RightChain bridges this gap through AI-powered optimization, expert support, integrated decision-making, and continuous improvement, enabling organizations to make faster, smarter, and more effective supply chain decisions.

Warehouse storage capacity should not automatically be designed for peak demand. The optimal size depends on the peak-to-average ratio and how long the peak lasts. Short, extreme peaks can be managed with temporary storage, off-site warehousing, or delayed inbound shipments, while longer, moderate peaks justify building capacity closer to peak requirements.

Honda’s warehouses were operating above 98% capacity, preventing the implementation of a new warehouse management system. By moving excess inventory to an off-site warehouse and reducing utilization to 85%, the company uncovered a large amount of unnecessary safety stock created by poor forecasting. This visibility drove major improvements to its forecasting process, inventory planning, and overall warehouse efficiency.

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.

Inventory levels are strongly influenced by trust. Poor visibility, missing supplier confirmations, and inaccurate inventory records encourage buyers to protect against stockouts by ordering excess stock. When teams cannot trust supply chain data, they compensate with inventory buffers. Improving visibility and inventory accuracy therefore reduces uncertainty, builds confidence, and helps eliminate unnecessary inventory.

Dr. Frazelle explains how sourcing decisions can determine whether a supply chain succeeds or fails, yet procurement teams may lack visibility into their broader operational impact. Understanding the full supply chain implications of sourcing choices helps professionals navigate critical trade-offs between cost, availability, risk, and service. Cross-functional education can transform procurement from a purchasing function into a driver of supply chain performance.
