This is a clever way to look at the process. At the end of the day anything going to market will need to be functional and able to be manufactured. As others have said, you won’t necessarily be doing the heavy technical parts yourself, but an understanding of what is involved to get your product made is always going to be useful.
Being able to speak to an engineer or tooling guy in their language means that you can work through potential problems as a team to make a product that is great on a design level as well as a technical/manufacture level. The same goes when working with business and marketing decision makers.
