This chapter continues where Chapter 11 left off, providing a detailed service modeling process that steps us through the individual tasks required to produce service and operation candidates.
How case studies are used: The RailCo environment is revisited with the intention of replacing its current set of services with well-defined business and application service layers. As we progress through the service modeling process at the beginning of this chapter, these new services take form while we assemble a series of service candidates that establish preliminary service layers.
Toward the end of this chapter, we join the TLS project team in a lengthy case study example that steps us through another modeling process during which we contrast different types of approaches to modeling service layers in response to new business requirements for the creation of a new SOA.
