The vision and purpose of effective IT service management is to efficiently develop, operate, and deliver services with value and alignment to the business. To do this, IT must transform itself from an organization with many silos of technical and functional silos into a business with reliable and cost-effective service offerings. The attitude, behavior, and culture of the organization must shift to a service provider organization. The first step in this transformation is to develop a service catalog that describes the IT services supporting the business services and in turn the business process.
