That's quite a mouthful, but it's also the title of a very useful presentation given by Erik Verdeyen and David De Block at last September's EuroIA Conference. Wish I could have been there; looks like this was one of many excellent talks. We need more UX people talking about the combination of UX and web analytics. (I've tried.) Anyway, this one is now officially favorited. Hat tip to Victor Lombardi for the link.
