What You Get, and What You Do Next

If you're building your first hardware product, one of the hardest things to work out is where one person's work ends and the next person's begins. Nobody publishes it, and most people assume you already know.

So here is what a design intent package is, plainly.

Design CAD. HD renderings. CMF specifications. Dimensioned drawings. A PDF presentation containing the design, the decisions behind it, and everything above.

Together that is what an engineering partner or a manufacturer needs to quote the part and take it into production engineering.

That does not mean the design arrives without manufacturing in it. A good industrial designer is thinking about how the thing gets made the entire time, because a form that can't be made isn't a design, it's a picture. I know where a parting line will want to sit and what a wall thickness is going to cost me. Sometimes I'll push for a more complicated part anyway, and when I do it's because it does something for the person holding the product, not because it looks better in a render. That is a discussion worth having with an engineer, and it's a different thing from not having thought about it.

What the package doesn't carry is the full production engineering. Draft angles resolved surface by surface, gate locations, tolerance stackups, the analysis that gets a part through a mold reliably at volume. That work is real and it's specialized, and it's the reason the next conversation exists.

The best version isn't a handoff at all. It's an engineering partner in the room early, while the CAD is still moving. An hour of their input in week three saves weeks in month five, because the watchouts arrive when the form can still absorb them rather than after it's locked. Some of my best projects have worked that way.

Which is why the question to ask early is who your engineering is. In-house team, contract manufacturer, partner studio. The answer changes the design. A CM's engineers will lean toward what their factory already does well. An in-house team can hold a form you'd otherwise give up. Knowing which one you have in month one is worth more than any amount of care in month five.

None of this is a warning. Design decides what the product is and what it's made of. Engineering decides how it gets made reliably at volume. The two overlap, and the projects that go well are the ones where the overlap starts early.
