As user experience evolves, new practices and techniques come into vogue. At the forefront of UX today are "Lean" and Agile UX methods and approaches. "Lean UX" has become a buzz term that has grown out of the Lean Startup movement, which is based on the Lean philosophy of Steve Blank and Eric Ries (see Eric Ries' book, Lean Startup). There's just one problem with Lean UX- what is it exactly, and how can it be implemented well? How does one approach "Lean" as an agency, a startup, a Fortune 100? It turns out there are a lot of interpretations of Lean UX in practice, and that a one-size-fits-all methodology may not be the answer. This diverse of Lean UX forerunners and practitioners will attempt to address these thorny questions. Panelists will spend a few minutes defining Lean UX on their own terms, including how Lean UX is similar and/or diffferent from Agile UX. Thereafter, panelists will spend 10-15 minutes digging into the nitty-gritty implementation details of how they are practicing Lean UX on a day-day level for company and client projects.
