Ops Meta-Metrics: Velocity 2010 Slides

As expected, Velocity was excellent this year. What an awesome time to be in this field. Caveat for those who didn’t see/hear my talk: the graphs and numbers in the slides are, for the most part, made up. But they’re also in line with what I’ve seen at Flickr and Etsy.
