Q. SOA Modeling – How SOA design is changing
Standard SOA practices are certainly useful (and often very practical), but what about making it even easier for the technology to reach out and creatively address specific business problems and/or concerns as they arise? What about giving users the ability to use SOA in a more creative manner? It’s really about analyzing where potential successes lie and then creating computing-based solutions (very often in a software environment these days).
SOA modeling is simply another step in the SOA journey; an advancement in approach to business.
Previous methodologies for developing SOA models might have put too much strain on certain individuals in ways that might have been unrealistic or completely foreign to them.
A classic scenario might involve managing tasks between a software designer / architect and a lead business analyst, for example.

See the figure on the right for an illustration of the communication amid trade procedure types and information types.Paul R. Smith Richard Sarfaty (1993).
