Regulations
Early Procurement vs Design Maturity
Business ContextLong lead times can require equipment commitments before engineering is complete. Waiting for full design maturity protects technical certainty but can delay delivery, while purchasing too early increases change and compatibility risk.
Brown Field Industrial Projects TRIZ ResolutionCommit progressively. Stable equipment characteristics and long-lead components can be secured early while uncertain interfaces remain adjustable through configurable specifications, hold points, or later-release information.
Applicable TRIZ Principles
Principle 10 – Prior Action: secures schedule-critical supply before final design completion.
Principle 15 – Dynamics: preserves adjustability in uncertain equipment characteristics.
Principle 1 – Segmentation: separates mature procurement information from unresolved details.
Expected Outcome
Earlier procurement
Lower delivery risk
Reduced redesign exposure
Greater specification flexibility
Decision IndicatorsEarly indicators that this contradiction is limiting project performance include:
Long-lead equipment waits for unrelated engineering completion.
Early purchase orders generate frequent changes.
Procurement milestones repeatedly threaten the schedule.
Equipment interfaces are fixed before site conditions are verified.
Specifications lack provisions for controlled later definition.
Monitoring these indicators helps organizations secure long-lead supply while preserving necessary design flexibility.
