You'd think this would be common sense. The common sense is metric tracking when dealing with incredibly intangible things in order to use data and statistics to make informed decisions. In my experience, it's almost always a complete waste of time adding overhead that's never recouped. It works best when you're producing X widgets where X is at least 10. When it comes to building something that hasn't been built before or doing custom work, most of that data can just be thrown out the window. A pessimistic guess is almost always better than trying to infer meaning from data into an existing narrative.
