| Scope freeze | Design ownership model: build-to-print, co-design, or clean-sheet target; Drawing package, BOM, CTQ list, prototype quantity, and target lead time | Quotation boundary, drawing revision, CTQ list, sample quantity, and test responsibility. |
| Process control | Design freeze, drawing revision control, BOM risk, and CTQ alignment; Assembly fixture strategy for airgap, magnet handling, and rotor balance | Material route, fixture plan, in-process checks, and supplier risk log. |
| Outgoing evidence | RFQ completeness, Revision control, Prototype gate coverage, Outgoing record set | Inspection report, electrical screen, mechanical screen, balance or thermal notes, and lot labels. |
| Repeat supply | Freeze the first quotation boundary: components only, subassembly, or complete motor.; Define production-intent materials, fixtures, and inspection records early.; Use drawing revision, effective lot, supplier change notice, and revalidation rules for every material or process change. | Effective-lot change control, corrective action loop, packaging standard, and shipment milestone plan. |
