Lately I’ve been coming across the terms “Lean Start-Up” and “Lean UX”. It seems like these are a set of concepts and tool sets that have been developed as a result of experiences in the fast phased tech start-up world. Generally the core idea in these is to rapidly iterate and re-iterate development of an application, UX design or a business model to make improvements based on customer feedback. This is to speed up the delivery of the end product that meets the customer needs or fine tune a business model to succeed while actively improvising. It looks like even an automotive company like Tesla has adopted such ideas. Two leaders of these ideas are Steve Blank and Jeff Gothelf.
