Core Scrum, barnacles, rumors and hearsay, improved version

What do Scrum, Crystal and Kanban have in common? They are all “reflective improvement frameworks”. In this section, Alistair describes Scrum as beautifully empty, and assertions about Scrum as core, barnacles, or rumor and hearsay. Burndown charts are barnacles, by the way, and planning poker is rumor and hearsay, just in case you were wondering. Thank you, Peter Green: who went to the trouble of enhancing the video quality and adding the side text.
