On a recent project I played a pretty active, if informal, role as an agile coach, in addition to my development duties. Which meant I did a lot of reading on plane flights, watched a lot of Jeff Sutherland videos, and got to the point where I could quote the Scrum Guide in chapter and verse. I'm not a certified anything (well at least as far as Agile is concerned), but the material started to make sense to me in a fairly coherent way, so I thought it might be useful to assemble a list of resources that influenced my thinking, and what I learned from them.
