Thanks for the article.

Got a couple of questions: "If you see a negative variance, it is a sign that something is wrong." -- what do you mean by variance here? What's negative variance? Whenever I see variance, I think (average squared) deviation from mean, so it can't be negative :)

Second, what metric do you use as basis for story points? What the estimation process looks like?

Pavel, thanks for your question!

According to your first question:

Nothing too complex here. We just use the formula: (E-A)/E * 100. In case Actual spent exceeds Estimated, we’ll receive negative number. Meaning we underestimated scope.

As for story points, it all depends on the team. Usually, we take the simplest thing to do as 1 story point and go from there.

Hope these answers will help you!

Let us know if still have some!
