Outsourcing Issues

I think choosing between one group for all of a companies outsourcing needs, or to pick multiple companies, I would want to pick one company. I think picking one company at first would cause for less confusion in the company. It would also be very easy at first to communicate with one company than many. I think also that if you have one company at first and then show them that you will leave them for someone cheaper, they will probably lower their cost to keep your business. Then you would not have to learn about a new company and have to learn how to communicate with them.
