The goal here is to build a prototype as soon as possible with the singular focus to build something to show and demo to users. And one way of doing it is building on top of a lot of prototyping software. So for example, if you're a software company, you will build a clickable prototype using something like Figma or Envision. If you're a hardware company or heart tech, it is possible to built a prototype. Maybe it takes you a little bit longer. The key here is 3D renderings to really show you the promise of what the product is.
