> Also, the minimization of time spent in meetings
I would argue that this should be "the minimization of unstructured/unguided/unclear meetings".
Tbh I've seen a non-trivial number of instances where engineers have wasted their own time or someone else's by not participating in organizational meetings - either by doing redundant work or having an unclear image of priorities/blockers/help needed.
Nobody want's to waste time in meetings, and most people who call meetings can't run them well. BUT having a well planned and executed meeting (30 mins tops) can save hours if not tens of hours of work time per week.
I also believe that the "just let the devs do dev work and avoid meetings" mantra is border-line meme status and (in my opinion) stems from toxic anti-social behavior, rather than efficiency. However, I also believe that meeting time per week should have an upper-bound (something like 4-6 hours, including a 15-min daily standup) to better enforce efficiency, rather than throwing 1-hour meetings all over the place and hoping they don't use all the time.
