They cover their phone receiver with their hand and whisper to you, “The executives are in a budget meeting, and we’re going to have our staff cut unless we can feed my VP some statistics to prove that our department keeps a lot of people busy. I need to know how many products we work on, how many developers fixed bugs, the average bugs fixed per developer, and how many of our fixed bugs were reported by customers. Right now!”
