Product Availability vs Inventory Cost
Differentiate inventory policies by regulatory risk—substances subject to REACH authorisation or import controls warrant higher service buffers than standard goods.

Regulations
Business Context
Higher inventory levels increase the probability that products will be available when customers require them. Inventory also consumes working capital, storage space, insurance, handling resources, and creates exposure to obsolescence or deterioration. Uniformly increasing stock improves availability at a potentially excessive economic cost.
Import Export TRIZ Resolution
Inventory can be differentiated according to demand stability, product criticality, replenishment time, margin, and substitution possibilities. High-service inventory is concentrated where shortages create material consequences, while predictable or low-impact products use leaner replenishment structures.
Applicable TRIZ Principles
Principle 1 – Segmentation differentiates inventory policies by product and service requirement.
Principle 3 – Local Quality positions different inventory levels according to local demand conditions.
Principle 23 – Feedback adjusts stock parameters using actual demand and service performance.
Expected Outcome
Higher product availability
Lower unnecessary inventory
Improved working-capital productivity
Better service differentiation
Decision Indicators
Early indicators that this contradiction is limiting inventory performance include:
Inventory increases without corresponding service improvement.
All products use similar service-level targets.
Slow-moving inventory accumulates while critical products stock out.
Inventory policies ignore replenishment variability.
Availability is improved primarily through additional stock.
Monitoring these indicators helps organizations protect availability by positioning inventory selectively rather than increasing it indiscriminately.
