ITIL: The Politics of IT Service Valuation

ITIL - Service Strategy: Service Valuation


Points to consider:

Service Value - "the true value of an IT service is only possible to ascertain in the context of the enterprise’s end-customer."

"It makes more sense to value IT services based on the risk the enterprise faces should its products not meet needs of its end-customers. Business risk then, not customer perception, is the right place to start valuing IT services."

"Measure the enterprise value at risk, and you have the basis for actionable and quantifiable decision-making that is inherently self-justifying. Empirically quantified enterprise value at risk may just be the long sought after means to attain the most elusive of IT desires—alignment with the business, control of costs, and quality improvements"

ITIL - Service Strategy: What is a Service Model

The definition of a service model is ‘a model that shows how service assets interact with customer assets to create value. 

Service models describe the structure of a service (how the configuration items fit together) and the dynamics of the service (activities, flow of resources and interactions). 

A service model can be used as a template or blueprint for multiple services.’
