01 · Recover identityThe part number is only a clue.
The real identity combines what the item is, what it does and every interface it must satisfy. Confirmed facts stay separate from assumptions, so a catalogue match is never mistaken for approval.
- Known
- OEM data, tags, drawings, manuals, history and physical evidence.
- Recovered
- Function, duty, dimensions, materials, interfaces and failure context.
- Still open
- Every missing fact that could change compatibility, safety or acceptance.
02 · Compare the routesFive ways forward. One controlled decision.
OEM, equivalent, repair, exchange and manufacture are tested against the same requirement. Lead time matters, but never outside compatibility, evidence, cost and operational exposure.
- OEM
- Confirm the original identity, current status and an executable authorised route.
- Equivalent
- Match duty, interfaces, materials and acceptance—not appearance alone.
- Repair
- Define repairability, restored condition, evidence and warranty.
- Exchange
- Control the core, configuration, lead time and return exposure.
- Manufacture
- Recover the technical basis, qualify the process and release the part.
03 · Make the decision defensibleEvidence is part of the product.
A replacement becomes commercially useful when the client can see why it fits, who must approve it and what has to be present before acceptance.
- Recovered identity
- Known facts, assumptions, duty, interfaces and missing data in one basis.
- Compatibility basis
- Why the route can fit—and every condition still requiring approval.
- Acceptance plan
- Certificates, inspections, tests, records and release responsibility.
- Commercial route
- Supplier, price, lead time, logistics, warranty and exclusions.
04 · From decision to deliveryThe route does not end at the quotation.
The approved basis becomes the order, the control plan and the delivery boundary. The physical item and the evidence required to accept it move through one visible responsibility.
- Approve
- The named technical authority confirms the selected compatibility basis.
- Order
- Identity, scope, evidence, Incoterm, warranty and exclusions become the baseline.
- Control
- Supplier, inspection, document and release points follow the agreed route.
- Deliver
- The accepted replacement and its required records arrive together.
