Simulation & Validation
In order to start the prototyping phase, a lot need to happen before that. Once your product idea is defined, you need to define all functions and basically the user experience. We are not here to explain all steps in between but basically you should come up by the end with a Product Requirement Docoment (PRD). This PRD will allow the engineers to start doing the work on the hardware and mechanical level, of course if the conceptual design has been done before. You might end up with a mock up in order to see a non-functional design but the game is to reach something that some beta users can manipulate and that we could call MVP (Minimum Viable Product). It will allow you to do few iterations if necessary and test your product in a real environment by your target customers. The MVP can have different meanings depending on your product and your requirement but basically this is a working prototype that some persons can use already..
