Service-Oriented Architecture: Applying Granularity

Applying the Right Granularity for Services

July 24, 2003

In a previous report, we described a best-practices framework for identifying services of appropriate granularity.

In this report, we apply the best-practices framework to a real-world example. In this case study, a list of candidate services (developed in actual Customer Scenario® Mapping exercises) is refined into a more complete list of the “right” services. In addition, you can see in practice how techniques that you learned with prior generations of IT technology can be repurposed to help you identify and create well-defined services.
