It&#x27;s rapid prototyping. It might just happen that the prototype is good enough to sell, but once you have a basis, comparisons can begin. If the prototype doesn&#x27;t have to act as the real product, just a skeleton, it&#x27;s not so hard to change the &quot;bones&quot; if something isn&#x27;t working properly.<p>If the prototype is quickly made, it could even count as part of that upfront design process.
