I’ve just had a look at Travis Birch’s Scrum poster over at Agile Advice: http://www.agileadvice.com/2014/03/20/referenceinformation/new-scrum-diagram-meet-scrum-by-travis-birch-csp/
I’m a big fan of showing how simple Scrum is (or at least trying). I’m not sure this poster achieves this (there is a lot on it), but it looks really good and doesn’t have anything on that I’d think of as wrong.
I think this would be really useful to print off and bring to a meeting. It could be used to stimulate discussion of roles or ceremonies within the framework.
