Estimation and estimates are for …
+ … deciding how much you can commit to in next iteration
+ … comparing estimated features and seeing which one is bigger
+ … deciding if you even want to push for this feature for that work needed
Estimations are not for…
– … evaluating your team speed
– … deciding to how much to bill your customer for the feature (especially when you later get angry that you billed to little)
– … treating them as deadlines
– … deciding that you spent enough on the story and now it’s time to cut corners.
