Under an ITaaS model, the IT service provider will place great emphasis on the needs and the outcomes required by the business to improve employee productivity and improving the top line (revenue) and bottom line (profitability).
The benefits to the business sought by using the ITaaS model include the standardization and simplification of products delivered by IT, improved financial transparency and more direct association of costs to consumption, and increased IT operational efficiency resulting from the need to compare the price of internally produced products to those available from external providers.
The transformation of an internal IT organization from operating as a cost-center to an ITaaS model is also believed to produce improved levels of business agility for the enterprise as a whole.
Vendors who are proponents of the concept of ITaaS as an operating model include EMC,[4] Citrix,[5] and VMware.
IT organizations that adopt ITaaS are most likely to use the best practices for IT service management as defined in ITIL.
