Minimum viable prototype

Since the acronym MVP is the same, it would be wise to consider that the definition of minimum viable product may be closer to that of a prototype than to a product.

The problem (according to [@cagan2018Inspired: how to create tech products customers love]) arose with The Lean Startup ([@ries2014The lean startup: how today's entrepreneurs use continuous innovation to create radically successful businesses]), in which the definition is a bit ambiguous. Do you want to build something that people can buy or something that you can use to test assumptions, features, and benefits to your users?
