What do managers do?

What is management? What do managers do? How do I manage?
These are standard questions that most of us in the management profession have been asked more than once. And questions we asked once in our careers too. Here, then, is a basic look at management, a primer, Management 101 from my perspective.

Art and Science
Management is both art and science. It is the art of making people more effective than they would have been without you. The science is in how you do that. There are four basic pillars: plan, organize, direct, and monitor.
Make Them More Effective
Four workers can make 6 units in an eight-hour shift without a manager. If I hire you to manage them and they still make 6 units a day, what is the benefit to my business of having hired you? On the other hand, if they now make 8 units per day, you, the manager, have value.

The same analogy applies to service, or retail, or teaching, or any other kind of work. Can your group handle more customer calls with you than without? Sell higher value merchandise? Impart knowledge more effectively? etc. That is the value of management - making a group of individual more effective.

Basic Management Skill #1: Plan
Management starts with planning. Good management starts with good planning. And proper prior planning prevents… well, you know the rest of that one.

Without a plan you will never succeed. If you happen to make it to the goal, it will have been by luck or chance and is not repeatable. You may make it as a flash-in-the-pan, an overnight sensation, but you will never have the track record of accomplishments of which success is made.

Figure out what your goal is (or listen when your boss tells you). Then figure out the best way to get there. What resources do you have? What can you get? Compare strengths and weaknesses of individuals and other resources. Will putting four workers on a task that takes 14 hours cost less than renting a machine that can do the same task with one worker in 6 hours? If you change the first shift from an 8 AM start to a 10 AM start, can they handle the early evening rush so you don't have to hire an extra person for the second shift?

Look at all the probable scenarios. Plan for them. Figure out the worst possible scenario and plan for that too. Evaluate your different plans and develop what, in your best judgement, will work the best and what you will do if it doesn't.

TIP: One of the most often overlooked management planning tools is the most effective. Ask the people doing the work for their input. (About.com)
