Solution
Purchasing and supply operations
Connect buyers to approved vendor, last replacement history, and engineering decisions that explain why a substitute was rejected.
People involved
- Buyers
- Supply chain
- Planning
- Engineering liaisons
Operational problem
Purchasing systems hold POs and vendors; engineering holds rejection rationales; operations holds urgency. Wrong substitute recreates old failures.
Information sources
- Purchase orders
- Vendor records
- Engineering decisions
- Approved part specifications
Common failure modes
- Cheaper alternate purchased after engineering rejection was forgotten
- Last successful vendor unknown to new buyer
- Commercial detail requested without authorization
Representative questions
- Which vendor supplied the last replacement assembly?
- Why was the earlier component specification rejected?
- Is this vendor approved for this part family?
Authority and revision requirements
- Approved vendor status
- Decision memory for rejected alts
- Part applicability
Experiential knowledge
- Supplier performance observations after review
Evidence required
- PO records
- Vendor master
- Engineering decision memos
Human approval boundaries
- Purchasing commitments and commercial terms remain human-owned
Expected qualitative value
Fewer repeat specification mistakes; faster recovery of last-known-good supply path.
