Can you walk us through your idea of the daily work of a manager, since you say it's "a job in itself"? I understand that if you give a person a title and tell them to sit around for 40 hours a week and collect a paycheck, they'll invent ways to stretch that out, but in real terms, what are the daily objectives that a manager must address? How many people can one manage before they need to commit their attention 100% to management? 10 subordinates? 5? 1? Is someone not a "real manager" as long as they have time to do code work on the side? Is a manager who does code automatically less qualified than one that would ensure his managerial duties exclude any time for other pursuits? Is someone only a legitimate "manager" if they went to school for it? Can it be self-taught? I've had management positions before so I have my own answers to these questions, but I'm curious about yours.
