Supplier's Category: All Prototyping Strategy: Consulting on "Looks-like/Works-like" build phases
Prototyping strategy consulting advises on build phases — the sequence of looks-like, works-like, and looks-like/works-like prototypes that de-risk a product before committing to production tooling. It’s planning-level guidance, distinct from actually building any one prototype.
Prototyping strategy exists specifically to sequence the other services in this directory correctly, so a design doesn’t jump straight from concept to expensive production tooling.
- Looks-like prototype: validates form and ergonomics, usually via 3D printing or CNC, no working electronics required
- Works-like prototype: validates function, often on a breadboard or hand-built chassis, ignoring final aesthetics
- Looks-like/works-like prototype: combines both, closest to a pre-production unit before tooling
Related terms: looks-like prototype, works-like prototype, engineering validation test (EVT), design validation test (DVT), production validation test (PVT), prototype build planning, tooling readiness assessment

What a good prototyping strategy consultant does
The value is in sequencing, not building — someone who tells you which prototype stage to skip or double down on given your risk profile and budget.
What to check
- Do they have hands-on experience across the actual manufacturing processes your prototypes will need
- Can they help select vendors for each build phase, or only advise on sequencing
- Do they tailor the plan to your funding and timeline constraints, not apply a fixed template
