As I was revising and writing new content for The Scrum Field Guide, 2nd edition, I emailed my friend Bill Hanlon at Microsoft to get his feedback on my existing chapter on bugs. Bill and I worked together years ago and I often value Bill’s opinion more than I value my own. The guy constantly innovates on things that others would say are good enough. Things are never good enough for Bill, and he’s constantly experimenting and trying new things.
