Outsourcing is the shift of IT infrastructure and systems development to external vendors. This is a good option for companies without the resources or technical capability to perform certain computing tasks. Tasks well suited to outsourcing include Web site hosting, Web design, development of custom software, and software maintenance. More basic tasks such as data entry and call center operation is often outsourced as well. Outsourcing often requires firms to enter into a service level agreement (SLA) that defines the specific responsibilities of the service provider.
