IT outsourcing (as a part of an outsourcing definition) is the use of external service providers to effectively deliver IT-enabled business process, application service and infrastructure solutions for business outcomes.
Outsourcing, which also includes utility services, software as a service and cloud-enabled outsourcing, helps clients to develop the right sourcing strategies and vision, select the right IT service providers, structure the best possible contracts, and govern deals for sustainable win-win relationships with external providers.
Outsourcing can enable enterprises to reduce costs, accelerate time to market, and take advantage of external expertise, assets and/or intellectual property.
