Can you tell us more about what they do well? I’m a dev who has often been encouraged to consider management but I’ve scared of the Peter Principle. I’m keen to learn from good examples.

If you're being encouraged to take up management, then they've probably already identified that you're already doing some of the right things.

I hate it when I promote a team lead, and they change what they've been doing. I promoted because they were already doing the job.

That’s good advice, thank you.
