Regulations
Business Context
International procurement frequently targets suppliers offering the lowest purchase price. Lower-cost sources may, however, involve longer lead times, weaker infrastructure, less mature quality systems, limited capacity, or greater geographic and political exposure. Savings achieved at purchase can consequently generate higher inventory, premium freight, quality failures, or service disruption. Organizations need competitive acquisition costs without creating an unreliable supply structure.
Import Export TRIZ Resolution
Instead of comparing suppliers primarily through quoted prices, organizations can segment sourcing decisions according to total supply requirements and incorporate reliability into supplier economics. Stable base demand can be allocated to efficient low-cost sources while critical or variable requirements use suppliers with stronger responsiveness. Supplier development and performance-based allocation can also improve reliability without automatically replacing economical sources.
Applicable TRIZ Principles
Principle 3 – Local Quality applies different sourcing criteria according to product and supply criticality.
Principle 23 – Feedback links future volume allocation to demonstrated supplier performance.
Principle 27 – Cheap Short-Living Objects uses economical sources where the consequences of failure remain limited rather than universally.
Expected Outcome
Lower total sourcing cost
Improved delivery reliability
Reduced emergency logistics
Better supplier allocation
Decision Indicators
Early indicators that this contradiction is limiting sourcing performance include:
Low-price suppliers generate frequent delivery exceptions.
Purchase savings are offset by premium freight or excess inventory.
Supplier selection gives little weight to reliability.
Critical products are sourced primarily according to unit price.
Procurement savings do not translate into lower total landed cost.
Monitoring these indicators helps distinguish genuine sourcing savings from costs transferred downstream.
