> We suck at measuring ourselves.

That is a certainty. I was once asked to calculate how much time we would save through our companies code reuse program. I read all the material on estimating savings, but then proved it was all ridiculous.

I came across a study that attempted to estimate how long it took to build libraries that had already been built. In this case, there were no unknowns, you had the entire code. Estimates were off by orders of magnitude. If we can't estimate the work when the work is already done, how could we ever estimate the work when we know less?
