Who he is, what he does. "Escape Velocity", why he wrote a book on agile metrics. What velocity is, rate of delivering value to customer, "it is useless", estimates are "bunk". "The business" pushes velocity based estimates. Lack of trust throughout organization. Can we really reduce a complex problem down to a simple number. Anti patterns: more velocity, cross team velocity comparisons, estimating with time, measuring individual velocity. Side effects of metrics. Variable velocity. What should we measure, cycle time and lead time, fixing bottle necks, code quality, team joy. Where does dev ops come in. How to find Doc's book. Upcoming conferences.
