An MVP is called a Minimum Viable Product. It's simply the smallest and easiest prototype you can create in order to learn more about your customer, their problem or if your solution will meet their needs. MVPs are not scaled down versions of your final solution. They might not even look like a final solution you have in mind. They simply exist as a means to test and learn and dispel assumptions. With each experiment you run, you'll likely want to create some kind of MVP in order to test the behavior of your test subject.
You should complete the following tasks before proceeding to the current one.
In order to gather data about your assumptions you need to run small and fast experiments. To run an experiment you create a statement about what you assume to be true, then you establish some kind of metric to measure. Design the experiment and then run it. No matter which direction it goes, you learn! Each time it is run you'll learn more about your customer, their problem, your solution. Example: Say you wanted to sell clothes online. You might create an experiment to test if people will sign up for your line of clothing. Your goal is to find 20 people who will sign up for your website updates. Your metric is 20 people and you talk to as many as you can. How do know who might sign up? You created an empathy map so you know their personas, what challenges they have, and what emotions they have. From that you might understand where they hang out and therefore how to reach them. Source as many as you can. Try to get them to sign up. Note the reasons why they do. Note reasons why they won't. Run the experiment for say 5 days. Then pause. Examine your results. Decide if you need to run it longer, change the experiment or if you have enough data to decide if your customer is genuinely interested in your product/service. The results only help you decide if you can move that assumption to a different place on the board. You may need more experiments or slightly different experiments as you think about what you learn with each customer interaction.
