1 illustrates the service life cycle principles. As depicted, this model is driven
by the strategy principle, which influences all aspects of the service life cycle, such as scheduling
life cycle initiatives and providing a detailed road map. The governance principle focuses on
service-oriented best practices and standards to facilitate proper life cycle management and execution
to oversee project activities. The structure principle elaborates on the life cycle framework
elements. The project funding system is another important principle, which introduces a fresh
look at service development and operations budgeting. The ROI principle emphasizes the importance
of tracking revenues incurred by service operations. Finally, the metamorphosis principle,
which embodies the service-oriented life cycle strategy, depicts service evolution during its life
span. Detailed explanations for life cycle principles are discussed in the sections that follow.
METAMORPHOSIS. In Chapter 1, the service-oriented metamorphosis paradigm is described as
one of the most essential aspects of service-oriented modeling. The evolutionary attribute of a
service and its ability to adapt to diverse development and production environments continues
