UX Lean (or Lean UX, take your pick) documentation lately: Jeff Gothelf's book, hearing him in person on the O'Reilly webcast, going to a Lean UX presentation at Minnebar, and pestering my senior usability expert about her opinions on the subject. I'm a firm believer that knowing a little bit about everyone's job gives you exactly what Lean UX strives for: shared understanding. Most of the time, however, at least to me, it seems as though they're playing catch up with Agile, but that somehow it's better because it's UX and PMs and the business driving frequent communication, iteration, and putting the minimal viable product in front of the customer, not developers.
And then I think, what do I really care as long as the outcome is the same and we get cross-functional, co-located, single focus, teams that iterate, adapt, and build something great.
Snarky: Our new PMO-driven Lean processes are an improvement over Agile as they won't come with the developer-centric baggage.
Title: I'm glad you're telling me our shared understanding.
