Pros and Cons of Outsourcing

Dear,

Could you please write me a text (not essay) that I could use to present. This means that there is no need for a large Introduction and/or conclusion. I would like you to write about the pros and cons of outsourcing. You can use some very brief examples at the end of a disadvantage or advantage in order to clarify the point. Could you please make use of some academic resources and if you can refer to a good economic article.
