As the guy who irritated his colleague Alvar I should answer to his post: First things first, was the “85%” made up? Yes, completely. Period. So why have I done this? It is a little trick to give critical people something questionable so they start to
make some research by them self and start a discussion. Nothing better can happen! So I knew that some teams at MS use SCRUM (or a modified version) and it worked, the discussion has started. Maybe this trick is unprofessional, but it work sometimes.
While you may have had the best intentions, this is the exact definition of trolling.
