I don’t know about pretending a correlation, but a common challenge for engineering and product ICs who are trying to become more senior or have a bigger impact is understanding how their work relates to the big picture. I often ask engineers why they are (to use your example) rewriting the login system, and is there is any way to quantify the results. This helps to avoid engineers polishing an already-round ball, and to have some kind of accountability for outcomes. If you are rewriting login to cut down on tech support calls or to make it work with third party auth or work with legacy enterprise garbage, all those reasons are tangible and possible to quantify.
