Theory and Practice of Internet SLAs. Two weeks ago I had the pleasure of sharing a podium with Chris Overton, Keynote's guru of statistics. Here's a PDF of Chris' segment of the presentation. Two out of 13 pages are a bit geeky (cosines and differentials), but there's a lot of food for thought. My favorite (and the source of a big Aha! for me) is the section entitled, "The large cumulative effect of nagging little penalties." (And what a great title, eh?) This is where Chris explains why it's so important to have mutliple SLA penalty thresholds rather than one big cliff. As he points out, if the vendor has already missed the threshold, what's to motivate it to keep trying? And if the vendor is likely to meet the objective, it also has no motivation.
