Traditional EVM makes no sense in software (and is potentially harmful) because claiming value earned based on intermediate work products--without an assertion of quality--does not provide reasonable forecasts. Agile provides an assertable and inspectable quality. Also, by ordering in terms of highest Business Value and risk considerations along with potentially shippable increments, I believe starts to include notions of value. Still, AgileEVM measures performance against plans (that can be re-baselined every iteration if needed). AgileEVM integrates cost management. Doing it well means not giving up what Agile offers: adaptive planning, quality.
