2 SERVICE-ORIENTED CONCEPTUALIZATION MODEL
GUIDING PRINCIPLES OF SERVICE-ORIENTED CONCEPTUALIZATION
The following guiding principles offer direction and best practices for establishing conceptual services
for projects. These tenets identify the major methods and process that the service-oriented
conceptualization discipline advocates. They address the fundamental concerns that the service
conceptualization approach is established on: generalization and specification of abstractions,
attribute-driven process, decision-driven process, and disjunctive and conjunctive service identi-
fication methods.
GENERALIZATION AND SPECIFICATION. Concept generalization activities should be applied
throughout the service conceptualization process to increase the scope and future capabilities of
conceptual services beyond the discovery state. Thus, the generalization process enables the expansion
of service concepts to higher abstraction levels, facilitating efficient future asset reusability.
The specification aspect, however, produces the opposite effect. It reduces conceptual service
concepts to lower abstraction levels and narrows their visibility and future functionality. Both
these approaches should be applied during the various conceptual service discovery and analysis
activities to adjust the conceptual levels of the treated services.
ATTRIBUTE-DRIVEN PROCESS. Attributes are descriptions of products that the business and
IT organizations propose to develop, and they should be the enduring artifacts of the service
conceptualization process.
