While the proof of concept helps us know if our ideas are even possible, the Concept Validation phase helps us find out if they’re any good.
CV builds typically work like the intended final product, but they’re made with non-production manufacturing methods so might not look the same. We might 3D print instead of injection mold, or CNC machine instead of casting. We’re looking for the cheapest, fastest way to build something that’s real enough to test.
This stage still requires creativity, but we’re adding a bit more process and structure too.
We’re focused on mimicking the eventual production design just enough to test. But where’s that line? We define “just enough” by translating our product goals into engineering requirements, and we let the requirements decide what functionality gets tested and how. Our CV build should be just mature enough to run these tests and help us gain confidence that our product goals are reasonable.
To perform well in the CV phase, a solid understanding of production and prototype manufacturing processes is extremely helpful, along with the ability to clearly define test procedures from product goals. We also have to be structured enough to track our test program and understand the results.
Who do you know who knows how things are made? How things are tested? Those people are extremely valuable during the CV phase.
