Looks like things are getting a little more intimate between Forbes and Kevin. World-class product development expertise and one of the most coveted business magazines in the world are back together again – almost sounds like a power couple in the making, am I right? Yep, our boss is back partnering with Forbes again. In the first article, Kevin shared some of his proven employee appreciation strategies to build a strong and connected team. The second article was about personal branding, an area Kevin absolutely excels at. This time he’s giving prototyping help for inventors in Miami. In this article, he’s giving you an overview of the five key stages of prototyping to help ensure your product will be market-ready.
“What do you mean by stages of prototyping?” you ask? It sounds expensive to have to build multiple iterations of your product right? And in your mind, you don’t need prototyping help because you’re so sure your amazing idea is going to work. So what’s the point of doing more than one prototype?
Let’s get back to basics.

Prototyping
Prototyping isn’t just for you to see how what the product looks like in a near-final form. It’s really for your target customers. Because you’ll want to get valuable feedback from them before you start selling. For inventors, prototyping is a process to help inventors find improvement opportunities to build a more streamlined, simpler, better-quality version of the product. As West Stringfellow recently mentioned on Kevin’s Product Startup Podcast, all the research in the world can’t tell you what the customer truly wants.
Inventors can help themselves by putting their prototype in the hands of their customers and simply talk to them. Learn what they like or dislike about your it. See if they’re using it the way you intended or if they’re neglecting key features of your product. Find out if it’s easy to use or if they just end up spinning the product in their hand with furrowed eyebrows as they determinedly look for something… but they’re not quite sure what.
Build the prototype. Measure the results from your customers. Learn how you can make your product better. And repeat until you think you’re ready.
And now, I think you’re ready for Kevin’s five stages of prototyping that separates a good product from a potential failure. It’s real prototyping help for inventors in Miami and all the other product development hubs in the US.

Five Prototype Methods for Developing an Invention Idea as a Startup
- Home-Built Prototype: Picture Tony Stark’s first Iron Man suit in that cave, minus the flamethrower and the like. Hacked together with parts from your local hardware store, it’s how invention makers can start to realize how their product might function and look like in the real world.
- Early Prototype: Stay on this stage too long and it might be one step forward, two steps back. Early prototypes are made with a very basic 3D CAD file developed by non-professionals or newcomers to CAD software. Because CAD is a standard in our industry, it might feel like it’s helping inventors because seems like they’re getting the illusion of results with roughly designed CAD. However, these kinds of prototypes made in this stage made by non-professionals are not well-made or complete enough to be for engineering or marketing.
- Rough Professional Prototype: As the name suggests, at this stage, you’ll have a professionally made CAD that’s suitable for 3D printing. Here, you’re testing functionality above all else.
- Cosmetic Prototype: Again, the name gives away the purpose of this stage. This stage is to help ensure your product looks as good as it functions. Nonfunctional, but great to use a stationary product for the purposes of marketing or crowdfunding your product.
- Professional-Grade Final Prototype: It’s got the aesthetics; it’s got the functionality. And for that reason, this is the prototype you’ll want to test extensively.
