These major modeling efforts should not center only on design and architectural artifacts such
as diagrams, charts, or blueprints. Indeed, modeling deliverables is a big part of a modeling
process. But the service-oriented modeling venture is chiefly about simulating the real world. It
is also about visualizing the final software product and envisioning the coexistence of services
in an interoperable computing environment. Therefore, the service-oriented modeling paradigm
advocates first creating a small replica of the ???big thing??? to represent its key characteristics and
behavior??”in other words, plan small, dream big; test small, execute big!
A VIRTUAL WORLD. How is it possible to simulate such a business and technological environment
that offers solutions to organizational business and technology problems? ???Simulating??? does
not necessarily mean starting with the construction of a software executable. It does not imply
instantly embarking on an implementation initiative to produce source code and build components
and services. The service-oriented modeling process begins with the construction of a miniature
replica on paper. This may involve modeling teams in whiteboard analysis, design, and architecture
sessions, or even the employment of software modeling tools that can visually illustrate the
solutions arrived at. Thus, the simulation process entails the creation of a virtual world in which
software constituents interface and collaborate to provide a viable remedy to an organizational
concern.
