Almost two months ago, I read this interesting post by Charity Majors about the cost of our slow CI/CD pipelines.  I was meaning to summarize and write about that article here but got distracted.  Gareth  Rushgrove pointed me at this fantastic google sheet calculator that actually quantifies the dollar value.  Plug in your own assumptions and you get a first-order approximation.  In my particular case, the opportunity cost of delaying pain relief to my suffering customers is much higher.
