It's funny how none of these articles mention http://www.leancanvas.com/ which was already released and in use when LLL was announced on stage at Startup Lessons Learned last year. See for example http://www.slideshare.net/ashmaurya/running-lean-canvas

Even earlier was Rob Fitzpatrick's implementation at www.thestartuptoolkit.com (since discontinued but see http://news.ycombinator.com/item?id=1774856 for some comments)

Enterprise product management is a very different problem from startup product management, but the underlying paradigm from Osterwald's "Business Model Generation" was developed for enterprise use so it may be a better fit.
