You understand XP. But you may have forgotten that the XP Customer selects
stories in the order of highest value / lowest cost first. Most teams that I
have worked with use at least a simple ranking of value such as H, M, L.

Also, I believe that Earned Value is generally not about the same kind of value
as business value. Earned Value as I understand it is about estimating the
percentage of COST thus far expended. Am I right on that, Glen?
