We meet the idea where it is
There's no standard starting point and we don't pretend there is. Some clients hand over a tight specification and want it engineered and built. Some have a working principle but no product around it. Some have already spent money elsewhere and ended up with a prototype that demos well and can't be manufactured. The first job is usually to pin down what the device actually has to do: what it measures, where it lives, how it's powered, what it has to survive, and what would make it a commercial success rather than a clever demo. Get that wrong and everything downstream is wasted money, so we spend real time on it before anyone lays out a board. Once it's clear, we carry the work the whole way to hardware you can sell.
