Industrial design studios sit in an awkward spot: the client trusts you with the product, but supplier conversations usually sit outside your retainer — and the fastest way to strain a client relationship is an RFQ that goes out before the design is supplier-ready. This checklist is written for the studio: what to verify, document, and flag before your client starts talking to factories.
Why this matters
The studio carries the blame radius. When the quote comes back at triple the target, or the assumed motor turns out not to exist at the price, the client remembers whose design it was — not whose sourcing assumption it was.
You don't need to become a sourcing firm to protect the project. You need a short list of supplier-readiness questions answered before the handoff, and a named backend resource for the ones outside a designer's scope.
Before you say 'this is manufacturable'
That sentence is a commitment, and clients hear it as one. Before saying it, a studio should hold three things: a documented motor/drive assumption, a named tooling-method assumption, and a target price that has been sanity-checked against a rough bill of materials. Without those, the honest phrasing is 'we designed it to be manufacturable — the assumptions still need validating'.
Document the motor and sourcing assumptions
In a motorized product the drive decides cost, noise, heat, durability, and supplier risk — so write the assumption down: assumed duty, power, mounting, noise ceiling, and where the assumption came from. A documented assumption can be validated; an undocumented one becomes the client's surprise.
Questions to raise without overstepping
You can ask 'has anyone validated the motor duty cycle?', 'has the target price been tested against a BOM?', and 'is there a second source for the drive?' without running the sourcing yourself. Raising them is design diligence, not scope creep — and it positions the studio as the adult in the room when the answers are 'not yet'.
What to flag to the client before supplier conversations begin
Four flags, in writing, before any RFQ: an unvalidated motor assumption, an untested target price, any single-source component, and an unnamed certification path for the client's markets. Flagging them early costs one email; discovering them in a factory's padded quote costs the relationship.
When to bring in backend feasibility support
When the motor, price, or second-source questions come back as assumptions, that's the moment for a backend feasibility read — one that sits behind the studio, not beside it. Done right (white-label, referral, or retainer), it complements the studio and never touches the client relationship: the studio stays the front door; the feasibility desk answers the questions outside its scope.
Decision rule: If the motor, the target price, or the second source is still an undocumented assumption, hold the RFQ and put a feasibility/readiness review between design sign-off and supplier outreach.
The studio's supplier-readiness checklist
- Motor/drive assumption documented: duty, power, mounting, noise ceiling, and its source
- Target price sanity-checked against a rough BOM, not just the client's hope
- Tooling method assumed and named (injection, stamping, casting)
- Single-source components identified — especially the motor
- Certification path named for the client's target markets
- Risks flagged to the client in writing before any RFQ goes out
- Backend feasibility resource named for questions outside studio scope
- Studio-client boundary agreed: who talks to suppliers, who owns the relationship
Common mistakes
- Saying 'manufacturable' when the honest version is 'designed to be manufacturable, unvalidated'.
- Letting the client send renders as an RFQ package.
- Treating supplier questions as not-the-studio's-job until the quote comes back wrong.
- Bringing in sourcing help that competes with the studio instead of sitting behind it.
