Regardless of their category, they are all conceived of
as service-oriented assets. Exhibit 16.4 illustrates the three major sections of the service-oriented
ecosystem pyramid. Note that the enabling SOA technology section is placed on the very top of
this hierarchical structure.
FORMAL ASSET UTILIZATION DIAGRAM FORMAT. In the previous sections, a service-oriented
ecosystem pyramid was described that identifies three major building blocks of a logical architecture
asset utilization diagram. These logical components are clearly associated by a hierarchical
relationship. The supporting technologies that are depicted on the bottom typically offer the organizational

technologies, typically enable organizational business execution. This three-dimensional logical
formation, however, may not be flexible enough to accommodate large implementations and allow
detailed description of asset interaction and collaboration. Therefore, a formal logical architecture
presentation should be visually flattened to enable the depiction of a larger technological
environment configuration.
