I do not believe you can manage people at all. You can manage all sorts of things in an environment that are frankly pretty perfunctory to allow people to achieve their goals – you manage the schedule, you manage the budget. But, you lead people.
If your interaction with a person ends with you thinking, “I need to manage what they do, or how they do it,” then you need to ask yourself some questions: Did I make a mistake assigning this person to this position? Did I make the goals clear? Were there enough resources available to get the job done?
