Have you ever told an employee, or even a peer, that she is going against expectations, and that she should do something differently? To a lot of us, this can feel very uncomfortable. We do not know how the other person will react.
This can be one of the hardest tasks in team management. I try to use a mix of the Socratic Method (teaching through constructive questions leading to a revelation by the student) and soliciting feedback on my own solution. I find this to be effective because the team member I’m speaking with will have a sense of being lead to the better path.
