Creating a Service Portfolio and ultimately publishing a Service Catalog provides the business customer with information they need on the cost and composition of a service. Frequently, we find that IT organizations have not adequately detailed the components of a service or the associated costs. This can lead to poor quality of the service due to inconsistent execution, the inability to modify the service easily given changes in the business and a lack of true understanding of the cost and value of the service in meeting the needs of the organization.
