Does this work best if your work is well-planned by someone else? E.g., you have a list of prioritized tickets with requirements complete, and can just code down the list? I work 32h/wk (mon-thu), and I feel happy with my productivity, but also recognize that I spend tons of time in meetings, clarifying requirements, helping other devs, etc. These aren't all really my role, so I could theoretically optimize them away and hope the invisible tasks get picked up successfully by someone else, but I know we'd have worse outcomes if I wasn't involved and "just" did my explicitly assigned tasks. Can someone with team lead/management responsibilities optimize for 'job done' this aggressively?
