The major factor in SOA success is governance. And good governance could not be done without a systematic approach to a service definition and inventory organization.
From "A methodology for Service Architectures" [OASIS]:
A common mistake when defining services is to have “services” called “GetCustomer” “UpdateCustomer” etc, these are not services, they are just invocation points “The why” elements on the services. The service is “Customer”, which has an interaction point of “Get”. Services are collections of processes, not individual processes themselves, hence the reason that “Get” is not a service.
