Countless times when people talk about doing an MVP, what they are really deep down looking to do is something that resembles the finished product. Or at the very least should be used as a quite feature heavy and robust stepping stone towards the finished product.
It is a misconception though. MVPs in its original definition are meant to be thrown away. They are meant to be product-imitations showcasing a critical hypothesis for your idea to potential customers in order to get hard data on what happens, when you throw it out there and – hopefully – the right people start taking notice and interact with it.
Looked at through that lens the MVP is just one way of validating your business idea and underlying hypothesis. In the test-library, I use, there are 59 other methods just like it. It is just a way of testing whether you can validate your idea and your critical assumptions. Nothing more.
