In this phase, you practice **Iterative Product Discovery**: - Start with less then viable product, a minimum viable **experiment** (MVE), e.g., just enough useful functionality for a top customer to validate their users actually *use* that functionality (and they were not just polite or excited about a solution they ultimately would not use) - Use Axure or a design tool and your preferred front-end framework to build these minimal **interactive prototypes** for the customer - Iterate towards a MVP, releasing some new, usable functionality during every weekly, fortnightly, or (worst) monthly cycle using the [Toyota Kata](A%20Kata%20Starter.md) - Keep refining the **storyboard** and use it to guide you - Determine at the beginning of each cycle what you want to learn, and possibly only focus on a very specific target persona at first - Gather feedback, monitor, and measure usage after each ([PDSA](The%20PDSA%20Cycle.md)) cycle - Take all and any shortcuts you can during discovery (e.g., only use an in-memory DB, not the real thing, etc.)
