This is definitely a challenge, but its also a challenge for engineers who are new to management as well. Rather than lead their team into becoming a problem solving group, they can jump in and just fix things to keep stuff moving along. The line between too 'hands off' and too 'hands on' is hard to navigate. Easier when there are other things taking your time but hard when you're in a hiring lull or there aren't any upper level things calling on you.
