RivetBridge / Inside the work
A purchasing decision, with its evidence attached.
Illustrative example — not a client engagement. Every supplier, quote and document in this enclosure scenario is fictional.
Decision question
Should the buyer approve tooling for an access-controller enclosure? Baseline: one enclosure, drawing Rev B, initial quantity 1,000. Material and finish requirements need confirmation from the engineering owner before the next gate.
QUALIFY — hold tooling approval. Close the identity, revision and sample-acceptance gaps before a commitment.
Evidence record
| ID | Question | Record | Limitation / gap | Next action |
|---|---|---|---|---|
| E-01 | Manufacturer identity | Quote A names only a seller | Manufacturing entity unresolved | Buyer requests identity evidence |
| E-02 | Drawing revision | Illustrative brief requires Rev B; Quote A cites Rev A | Technical mismatch | Engineer resolves revision and requests corrected quote |
| E-03 | Quoted price | A: $8.20 + $1,200 tooling; B: $8.90 + $0 separate tooling | Illustrative quotes only; other costs unknown | Buyer confirms delivery basis and exclusions |
| E-04 | Sample acceptance | No signed sample criteria supplied | No product approval established | Engineer defines checks before ordering samples |
Comparable economics
At 1,000 units, A’s quoted subtotal is $9,400 versus B’s $8,900. At 5,000 units, A is $42,200 versus B’s $44,500. The price ordering changes with quantity. Neither comparison resolves the revision mismatch or includes freight, duties, testing or unquoted costs.
The spreadsheet lets you change quantity and quoted costs. It does not select an approved supplier.
Next-gate plan
- Buyer: obtain manufacturing-entity evidence before requesting a revised commercial offer.
- Engineer: resolve Rev A / Rev B and confirm material, finish and acceptance criteria before sample commitment.
- Buyer: obtain comparable delivery and cost assumptions before price approval.
- Approvers: review the updated record. Set target dates together before starting these actions.
Decision note
KEEP both offers as records for comparison. QUALIFY the missing evidence. STOP the proposed tooling commitment until the assigned reviewers close the gaps. These labels apply to this decision and are not supplier ratings or a reliability guarantee.
