A minimal viable product is a kind of prototype where big projects have their real-time prototypes to see how their project performs in real-time without any issues. The same goes with the software, before getting into a huge system it's good to test the process by developing a simple MVP that resembles the same features and functionalities. So, everyone who is on the way to investing big will be making an MVP to see if the idea works and then move on to the whole investment for the mega project.
