Comments

Mike: The Agile 2006 article includes these two sentences: "An equivalent measure to CPI can be observed as: Planned Costs / Actual Costs. An overrun occurs when the Actual Costs are over the Planned Costs, and the CPI value is < 1."

However, comparison of actual cost to planned cost is what Earned Value Management works so hard to eliminate. In other words, if feature completion is ahead of schedule, there may be no overrun at all, even though actual costs are over planned costs. If we don't compare actual cost to earned value, we can't know the cost performance until all features are complete.

I do agree with tracking schedule performance using feature completion, and I recommend an Earned Schedule approach instead of showing schedule variances vertically, as in Figure 7. See www.earnedschedule.com /Garry

What are good EVA equivalent metrics to track on agile projects and how do we track them ? The frequency is also important, so what gives the most valuable info.

Hi Ipsita,

Feature or story tracking provides the equivalent EVA metrics on agile projects. If you download the paper listed in the article and look on page 5 it explains how metrics such as EV, CPI and SPI can be calculated for agile projects.

Mike
