Rich Mironov's talk on April 4, 2014 for Cisco IPTV:
How do we understand what software product managers do, how this overlaps - but isn't exactly the same - as agile product owners, and what are the failure modes for product teams at commercial software companies? Especially when scaling up large commercial software programs (dozens or hundreds of teams), are there organizational maps that work? All teams aren't the same, so how do we match product owner skills/backgrounds to teams?
