Definitions
Outsourcing is the transfer of activities, that were previously conducted in-house, to a third party (Arjan J Van Weele, 2004)
Outsourcing means that the company divests itself of the resources to fullfil a particular activity to another company to focus more effectively on its own competence (NEVI, 2000)
Outsourcing is the decision and subsequent transfer process by which activities that constitute a function, that earlier have been carried out within the company, are instead purchased from an external supplier (Axelsson and Wynstra, 2002)
