Some weeks ago I gave a talk at AgileDay.it. My talk was about a weird experimental Kanban board, and the Leitmotiv I used was around the differences between Principles and Rules. The topic was: we often learn methodologies mocking rules (often, without getting the point) rather than trying to understand the principles behind them. This bad habit sometimes leads us to take really dumb decisions.
Well, if only I had seen then what I saw today, I would have used in my talk, since I think it would have been the perfect example.
