Marc Haine gives new managers advice on the transition from peer to leader. He covers preparing new hires with a toolkit, supporting them after they start, and managing the shift from friendship to professional relationships. He introduces the concept of a "first team" (your leadership peers) versus your "second team" (the people you directly lead).
Give people the toolkit before they get the job and then give them the support after they get the job. Help them explain that you're no longer their friend. You can still be their friend outside of work, but it's a challenging dynamic to have and help them manage it. There was a concept more at a leadership level which I did like, which was your first team and your second team. If I go to the chief marketing officer of a company and say, what is your team? Instantly, what they'll tell me is, "I lead the the marketing team. The marketing is my team." It's like, "No, that's your second team. Your first team is your leadership team. So your first team is the leaders that you work with, your peers. So your team to make the company successful isn't the marketing team. That's the team you lead. Your peers and your team are the chief technology officer, chief operating officer." The chief strategy, the customer services people, that leadership.
