Beyond Hierarchy: Towards a Service Model supporting new Sourcing Strategies for IT Services
Beyond the classic hierarchical customer/provider relationship, service providers are more and more cooperating with each other on an equal footing. Service modeling techniques have been applied successfully to hierarchical sourcing strategies as a blueprint for service management processes and to define the basis for describing the communication and collaboration between IT service providers. In this paper, we analyze the additional requirements to service modeling arising from alternative sourcing strategies and propose an extension to the MNM (Munich Network Management) service model. An application to a service in use shows how the new concepts incorporated in the service model can be used to properly describe complex provider collaboration scenarios.
