Inside you there is a secret product idea...some problem you are just itching to solve. Yet it falls prey to that deadly statement: “Someday, when I have more time...” In this action-packed 180 minutes, UX London participants got their ideas out and into the world. Using Lean Startup principles and these fun and rapid methods, they created a coherent, lo-fi product concept and got peer feedback on it. From identifying the problem it solves for people and understanding the role it plays in customers’ lives to identifying a key metric to indicate traction, they explored the idea in full. They wrapped up with practical, actionable (and simple!) next steps to propel the ideas forward.
