> How many engineers are doing things like using real numbers from previous work to build models before estimating? Fogbugz created a feature called Evidence-based Scheduling (http://help.fogcreek.com/7676/evidence-based-scheduling-ebs http://help.fogcreek.com/7676/evidence-based-scheduling-ebs). It's probably the only real quantitative approach that I have seen while working on web development projects. I'm probably wrong to assume that more "technical" fields like aerospace do much, much more than this, but it was really interesting to use this with what was mostly CRUD-work. EDIT: added link.
