"Service-Oriented Modeling (SOA): Service Analysis, Design, and Architecture"

Analysis services that are characterized as business types are typically evaluated
on the basis of business functionality. These entities provide purely product implementations and
execute business strategies. Thus, the way to classify them should be chiefly influenced by their
offered processes and less driven by their enabling technical mechanisms. For instance, a product
that offers mutual fund trading services and typically performs mutual fund ordering activities on
behalf of consumers should be regarded as a business service type. In many cases, practitioners
may have second thoughts about their typing conclusions because of the dominant supporting
technologies. But these are characteristically the enabling aspects of the business and should not
sway a practitioner??™s judgment.
To help in categorizing the context of a service, ask the following domain analysis
questions:
??? Does this service provide business solutions to existing enterprise problems?
??? What are the problems that this service is proposing to resolve?
??? Does it tackle organizational business concerns?
??? What is the main justification and motivation behind constructing such a service?
If all the answers are associated more with the business and less with technological aspects,
the right answer may be at hand. Indeed, typing a service context can be a challenging engagement
when neither the business nor the technology aspects are dominant enough.
