Proof-of-Concept Prototypes versus Manufacturing Design Preparations
I have designed many early-stage proof-of-concept POC circuits, and observed many others do the same thing. It seems that there is often a huge disconnect between clients and engineers, though, when it comes to the goals of a POC design.
In simple terms, an engineer worth his salt will overdesign an early POC circuit. This is because Murphy’s law always applies, and POCs are about overcoming unknowns. By overdesigning the circuit, one is able to prove the client’s product POC can be made to work, and quickly.So, what types of things should be overdesigned? Here is a short list. However, the nature of the design will likely call for more determining what is appropriate is part of why real engineers are paid higher than “sanitation engineers”:
