Couple questions answered about the last post:
Quatloo is from Star Trek: TOS, "The Masters of Triskelion" later parodied on the Simpsons when Burns bets quatloos on the newcomer. Not intended to be pejorative: I still measure projects in quatloos myself (well, "Torpex Work Units", I call them), multiplying by various fudge factors to try and get a date and budget.
When I say scrum doesn't measure velocity in quatloos, that's from Cohn's *Agile Estimating And Planning* - they measure the whole project, or the release burndown, in story points, but each sprint they re-estimate the tasks in man-days, and that's what they track velocity in. Double checking: yes, it's in Schwaber's book too: the project backlog burndown chart uses coarse-grained estimates multiplied by a fudge-factor, then each sprint re-estimates.
Looking it up, I just noticed Schwaber does suggest using the project burndown chart to estimate when the project will complete (p. 11 of Agile Project Management With Scrum), so it is the quatloo-velocity that really matters to him too, it seems. But that's the velocity that I find flattens out over time.
And...I don't know what to say about Gregg's experience. I'm jealous, and maybe should go work with him.
