16 INTEROPERABILITY PERSPECTIVE BENEFITS AND BEST PRACTICES
products facilitate the enforcement of service-level agreements and message security. Finally, the
SOA governance product enforces policies through the ESB product.
Exhibit 16.16 identifies the major contributions of the logical architecture interoperability
perspective and recommended best practices.
DELIVERABLES
The service-oriented logical architecture phase requires that two major artifacts be provided: an
asset utilization diagram and a transaction directory diagram. Each of these deliverables should
serve as fundamental units of analysis for the physical implementation of the organizational
production environment.
??? Asset utilization diagram. Provide an asset utilization diagram that depicts the chosen
integration strategy. This artifact identifies the participating service-oriented packaged
assets in a solution and provides in-depth and detailed descriptions of asset interaction,
collaboration, and utilization. The asset utilization diagram can also be employed to carve
out a service-oriented consumption strategy on which service-level agreements (SLAs)
between consumers and services are established.
??? Transaction directory diagram. Furnish transaction descriptions of integrated assets.
This diagram should present high-level business or technological activities that are managed
by formalized transactions.
SUMMARY
The logical architecture discipline facilitates integration planning of service-oriented packaged
software solutions.
