Problem:
You have been asked by HR to produce a job description for a production line management position in your department. You are happy for this opportunity because you have witnessed several of your coworkers on the line become newly promoted managers, only to fail and return to the production line. In one instance, your friend, Hal, was so unhappy about the experience that he left the company. You hated to see this happen, as Hal had been a good friend, and you felt the entire unfortunate situation could have been avoided.
Now is your chance to help prevent future replays of this painful (and for the company, expensive) occurrence. Fully describe the four functions of managers so the next applicant will better understand the complexities of managing people. Use as many concrete examples as you can, in the context of a production line in a company.
