TL;DR: If you work in tech, you’ve heard of the “dual career ladder”. As engineers grow, they can choose to climb the “technical ladder”, or they can climb the “management ladder”.
It’s commonly said that managers of technical teams should understand technology so that they can be effective.
Just like managers should understand technical issues, engineers should understand management issues to be effective.
One way to do this is to just ask your manager. Why do we do “calibrations” as part of performance management? Who decides who gets promoted? What are the dimensions you evaluate people against? Sometimes those processes are well-designed and work as intended, but sometimes they’re not. In either case, you should try to understand them.
