Business Context

Maintaining inventory protects projects against delivery delays, shortages, and supplier disruption. However, purchasing materials substantially before installation ties up working capital, creates financing costs, and increases exposure to damage or design changes.

Real Estate & Construction TRIZ Resolution

Inventory should be differentiated according to supply uncertainty and production criticality. Critical long-lead materials can receive strategic buffers, while predictable items use scheduled replenishment, supplier-held inventory, consolidation centers, or phased release arrangements.

Applicable TRIZ Principles

Principle 1 – Segmentation establishes different inventory policies according to material criticality.

Principle 19 – Periodic Action replenishes materials according to production cycles.

Principle 24 – Intermediary positions selected inventory with suppliers or logistics partners until required.

Expected Outcome

Reliable material availability

Lower working-capital requirements

Reduced excess inventory

Improved supply continuity

Decision Indicators

Early indicators include:

Large inventories remain unused for extended periods.

Working capital increases substantially ahead of installation.

Critical materials receive the same inventory policy as easily sourced items.

Material shortages occur despite high overall inventory.

Early purchases become obsolete following design changes.
