Thanks for the links. I'll be reading for a while I guess.

"Traditional" covers a lot of ground. In past projects (70s) I budgeted
cost and scheduled work completion by month. I reported actual expenditure
versus budget, actual work complete against plan and the ratio of the
two - I believe we made up a name for the ratio, but I can't recall it.

Of course, none of this measured anything except our adherance to plan.
We could be right on schedule and still have the whole thing turn out
to be a waste of time. :-)

Has anyone tried to match the XP notion of value to EVMS? What I mean
by this is if we have completed some set of stories at some cost, do
you differentiate the result from some other set of stories at the
same cost, but having less [xp] value? Or less value in the real
world? [costs avoided, lives saved, etc.]

This seems as if it would be pretty hard to do - and maybe not worth
the effort. Or maybe outside the scope of IT - except that I seem
to remember who got blamed when well-done projects didn't actually
produce the hoped-for end results.
