Sampling and prototypes
Last updated:
Plan sampling by giving every sample round one clear question to answer, so you stop as soon as the product is right.
Right Prototypes is the second step of Cydney Mar’s Concept-to-Reality Pathway: develop the right samples and cut costly rework. MVP to Shelf explains how to brief samples, how to judge them, and when to move on to suppliers.
There is no fixed number. It depends on product complexity and how clear your brief is. A focused hero product with a complete tech pack usually needs fewer rounds than a vague brief with several options.
Send sketches, materials, measurements and construction notes. See the tech pack format guide.
Check function and overall form. Note every change in writing.
Check fit, material, finish and how it feels in the hand.
This becomes the standard production is measured against.
| Type | Purpose | When to use it |
|---|---|---|
| Prototype or proof of concept | Prove it can be made at all | Before you know the idea is feasible |
| Development sample | Refine function, fit and materials | During revision rounds |
| Approval sample | Set the standard for production | Before you place a production order |
| Pre-production sample | Confirm the factory can repeat it | Right before the first run |
Definition
In MVP to Shelf’s terms, the right prototype is the one that answers your current question and nothing more. Early on that is whether the product works. Later it is whether it feels right, then whether a factory can repeat it. Asking all of those at once is how rework multiplies.

Studio Red notes that very simple physical MVPs often use off-the-shelf components and low-risk manufacturing methods like 3D printing. Using existing parts where you can keeps early rounds affordable.
