““Part of the problem is the perceived need to fill a whole day with management stuff, regardless of whether it’s called for or not. All those dreaded status meetings, interruptions for estimates, and planning sessions have a curious way of adding up exactly to a manager’s workweek. While monitoring output is sometimes quite important, it’s rarely a forty-hour-per-week position. Ten hours maybe, but few full-time managers have the courage to limit their presence to that.””
