There are a lot of benefits of MVP but the true benefit of a it is that we are able to construct something that will address the initial concern of your public in a timely matter. It is important because your whole product requires days or months to be completed, determine what are the minimum requirements that will work for your user base and release that, then move forward with another process that will enhance your product.
It also provides an answer to constructing a feature in a timely matter while adjusting for the customer needs.
One of the major advantages of building an MVP is that it helps you legalize your product, ideas or services which quickly helps us to decide whether to continue to go after your product idea and if so, whether and how to modify it.
It also helps in testing the product in real market.
