I vote for a topic called, “What the hell is this agile thing anyway?” And just have it be the 101 of why agile. It may sound like ‘old hat’ to anybody in the space, but people are still finding out for the first time what agile is. Or if not that, have practiced ‘cargo cult’ agile. They use the word, but have never seen the principles and don’t know why they do things.
I admit, I’m planning to run something similar at a knowledge share at work next week. I can let you know how it goes.
