In this step you'll learn about the Lean Startup by author Eric Ries. The book focuses on how to validate an idea without wasting a bunch of time and effort building something that nobody wants. The process includes writing out a vision for the user experience, identifying any assumptions you've made, building an early version of your product, and showing your MVP to a small segment of target customers. Finally, you have to decide to pivot or persevere based on the customer's reaction."
