The type of ACTIVITIES that a company outsources varies from business to business. If there's a particular activity in the back office that is important but not the core business of the company, they would consider outsourcing it. SIMILARLY, some companies can even OUTSOURCE some of their front office activities.

For Example: the initial process of Passport processing in India is outsourced because that is information COLLECTION. However, the back office is maintained by government because that is information verification which needs more control.
