Availability vs Inventory Investment
Segment inventory by velocity and criticality, using network pooling and drop-ship to decouple availability from local stock ownership.

Business Context
Product availability is one of the primary functions of wholesale distribution. Customers depend on distributors to provide products when manufacturers cannot supply them quickly enough or when direct purchasing would be impractical. Maintaining high availability, however, traditionally requires greater inventory investment. As service expectations increase, distributors may add stock across more SKUs and locations, tying up working capital and increasing storage and obsolescence exposure. The challenge is to improve customer access to products without making inventory investment the primary mechanism for achieving availability.
Wholesale Distribution TRIZ Resolution
Availability should be separated from physical inventory ownership at every location. High-velocity and critical products can remain locally stocked, while slower-moving products can be pooled at central facilities, transferred between branches, sourced rapidly from suppliers, fulfilled directly, or supported through approved substitutes. Network-wide inventory visibility allows existing stock to serve a larger demand base, while differentiated replenishment policies align inventory investment with actual service requirements.
Applicable TRIZ Principles
Principle 1 – Segmentation separates products according to velocity, criticality, value, and service requirements so each receives an appropriate stocking strategy.
Principle 17 – Another Dimension expands availability beyond individual branches by using inventory across multiple network levels and locations.
Principle 24 – Intermediary uses central facilities, suppliers, and alternative locations to provide product access without requiring local ownership of every SKU.
Expected Outcome
Higher product availability
Lower inventory investment
Better network inventory utilization
Reduced working-capital requirements
Decision Indicators
Early indicators that this contradiction is limiting inventory performance include:
Inventory investment increases faster than service performance.
Similar slow-moving products are stocked across multiple locations.
Stockouts occur in one facility while inventory exists elsewhere.
Availability targets are achieved primarily through higher safety stocks.
Working capital grows faster than sales.
Monitoring these indicators helps determine whether availability is being created through intelligent supply-system design or simply through additional inventory.
