My background is the opposite; I'm a mediocre software engineer but have quite good people skills. I'm experienced enough to know what takes time and which parts of the system are more critical than others. I have a few senior engineers whom I really listen to carefully and to whom I give a lot of trust and empowerment. I don't make design decisions, they do and I give input. I take responsibility when we fail (and learn from it) and give the team credit when we succeed. In my humble opinion, being a manager is more about people than anything else.
