This week, a peer in the Agile community put the following question to a number of us: "If you could recommend one Agile book to a manager what would that be?"

His question generated some thoughtful responses and ultimately a number of titles which I've collected here. I share this because I think his goal is not uncommon these days - certainly I'm facing it myself among those in the northern New England business community who are skeptical, risk-averse or just have been burned by product/software development promises that have fallen (painfully) short.
