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.
  
2:Organize
Now  that you have a plan, you have to make it happen. Is everything ready  ahead of your group so the right stuff will get to your group at the  right time? Is your group prepared to do its part of the plan? Is the  downstream organization ready for what your group will deliver and when  it will arrive?
Are the workers trained? Are they motivated? Do  they have the equipment they need? Are there spare parts available for  the equipment? Has purchasing ordered the material? Is it the right  stuff? Will it get here on the appropriate schedule?
Do the  legwork to make sure everything needed to execute the plan is ready to  go, or will be when it is needed. Check back to make sure that everyone  understands their role and the importance of their role to the overall  success.  
3:Direct
Now  flip the "ON" switch. Tell people what they need to do. I like to think  of this part like conducting an orchestra. Everyone in the orchestra  has the music in front of them. They know which section is playing which  piece and when. They know when to come in, what to play, and when to  stop again. The conductor cues each section to make the music happen.  That's your job here. You've given all your musicians (workers) the  sheet music (the plan). You have the right number of musicians (workers)  in each section (department), and you've arranged the sections on stage  so the music will sound best (you have organized the work). Now you  need only to tap the podium lightly with your baton to get their  attention and give the downbeat.  
4:Monitor
Now  that you have everything moving, you have to keep an eye on things.  Make sure everything is going according to the plan. When it isn't going  according to plan, you need to step in and adjust the plan, just as the  orchestra conductor will adjust the tempo.
Problems will come up.  Someone will get sick. A part won't be delivered on time. A key  customer will go bankrupt. That is why you developed a contingency plan  in the first place. You, as the manager, have to be always aware of  what's going on so you can make the adjustments required.
This is  an iterative process. When something is out of sync, you need to Plan a  fix, Organize the resources to make it work, Direct the people who will  make it happen, and continue to Monitor the effect of the change.
