Yes, I mean the explicit estimation of the value of a feature in dollars.

Not at all.  Are you saying that part of the current definition of the
Customer role is to do that estimation in dollars?  I haven't come across
that.  I was only aware of prioritization, not valuation.  If it is, then
moving to an EVMS approach wouldn't be a big deal at all.  Assuming
valuation is not currently part of the process, what implications do you
think introducing it would have?

Best regards,
Bill
