Except you’re self selecting for a company that has high engineering costs, big fat margins to accommodate expenses like additional hardware, and lots of projects for engineers to work on.

The evaluation needs to happen in the margins, even if it saves pennies/year on the dollar, it’s best to have those engineers doing that than have them idling.

The problem is that almost no one is doing it, because the way we make these decisions has nothing to do with the economical calculus behind, most people just do “what Google does”, which explains a lot of the disfunction.
