In the previous paper “Enterprise Architecture and ITIL®: Implementing Service Strategy", Trevor Lea-Cox looked at some important concepts in Service Strategy including how to define Services, the concept of Market Spaces and the concept of Value Chains.

He then looked at a brief summary of each of the ITIL Service Strategy processes and concluded with a small example applied to an EA department to illustrate the principles.

In this paper on Service Design, Trevor reviews some important principles used by ITIL in the design of IT Services and summarizes the main ITIL processes for managing Service Design. Trevor also considers how these principles are applied to designing one of the Services identified in the Service Strategy.
