What are
these logical architecture perspectives? They reflect the technological assets??™ behavioral patterns
and execution of business processes. They are also about identifying reusability opportunities
and reducing asset dependencies. Furthermore, they are clearly about avoiding tightly coupled
implementations and controlling unwieldy asset distribution conditions. This is what it means to
carve out a logical architecture strategy.
Exhibit 16.1 illustrates these fundamental perspectives of service-oriented logical
architecture.

building blocks of the asset utilization diagram should be identified. This artifact is a visual aid
that can assist in planning the general organization of the logical environment and in depicting the
hierarchical relationship between technological assets. Furthermore, the asset utilization diagram
illustrates the collaboration between packaged technological assets. This visual interaction facilitates
a consumption and reusability strategy in which service functionality capacity is measured
and communicated to its consumers.
