Related to yesterday’s post and to an entry I wrote two years ago on measurement, I just found an old (2003) post from Martin Fowler on why we can’t measure productivity in software development. He’s much clearer than I am, and his article is well worth reading. His conclusion:
I can see why measuring productivity is so seductive. If we could do it we could assess software much more easily and objectively than we can now. But false measures only make things worse. This is somewhere I think we have to admit to our ignorance.
