IT outsourcing is a phrase used to describe the practice of seeking resources -- or subcontracting -- outside of an organizational structure for all or part of an IT (Information Technology) function. An organization would use IT outsourcing for functions ranging from infrastructure to software development, maintenance and support. For example, an enterprise might outsource its IT management because it is cheaper to contract a third party to do so than it would be to build its own in-house IT management team. Or a company might outsource all of its data storage needs because it does not want to buy and maintain its own data storage devices. Most large organizations only outsource a portion of any given IT function.
