Would you Rather get an Outside Service to do the Inside Work?

There is an old Dr. Edward Deming way of looking at a corporation that that comes to my mind from time to time.

The short essence of it is this: If you could, would you use the various departments in your company or would you rather get an outside service to do the work? An interesting question.

So I am asking you. If you could, would you use your current production, edit, or sales teams, or would you rather get the same services somewhere else? Think about it up and down the corporate chain. What would really be best from your departments perspective?
