Hardware planning
How to shortlist a hardware manufacturing supplier
Shortlist suppliers against your actual build: process, material, critical features, quantity, inspection, and delivery needs. Then request evidence for the proposed facility and agree on a pilot before committing to repeat production.

Build your project brief →1. Define the work before searching
Write one scope that every candidate receives. Identify what you already own and what the supplier must develop. A shop making parts from released drawings and a partner completing the design solve different problems.
- Name the part or assembly, revision, process, material, finish, and order quantity.
- Identify critical features and the evidence required to accept the build.
- Separate the pilot order from a forecast; describe the expected ramp without treating it as a purchase commitment.
2. Request evidence for your project
Treat directory capabilities as discovery information. Ask the proposed supplier to explain how it would deliver this specific scope. NIST MEP's supplier-selection guidance covers capabilities, quality systems, capacity, and continuity; use those topics to structure the conversation.
- Ask for comparable work in the proposed process and material, with confidential customer details removed.
- Confirm which facility performs the work and which steps are subcontracted.
- Request an example inspection report and an explanation of rejected-part handling.
- Discuss capacity for your order and a backup plan for critical equipment or staff.
3. Agree on a pilot and a decision record
Set the pilot's acceptance criteria before placing the order. Record the quantities, measurements, functional checks, reports, and decision owner. Keep open questions visible rather than translating missing evidence into a score.
- Record each requirement as supported, pending confirmation, or outside scope.
- Assign an owner and due date to every unresolved requirement.
- Define the next action if the pilot fails: investigation, rework, another pilot, or another candidate.
Example: a robotics enclosure
For an illustrative 25-unit enclosure pilot, compare candidates on bends, inserts, finish, and assembled fit. A machining capability does not establish sheet-metal expertise. Ask how each candidate checks the same fit-critical features and supplies the agreed inspection results. Choose only after resolving those requirements and the quote exclusions.
Decision checklist
- One shared scope and drawing revision
- Proposed facility and subcontracted steps recorded
- Relevant experience and inspection evidence requested
- Pilot acceptance criteria and decision owner agreed
- Open questions resolved before repeat-order commitment
