intermediate result, which appears in the right-hand column, represents the composite
service A, along with its two subordinate services.
Step 2. This step is depicted in Exhibit 7.23. The unification analysis operation on the composite
service M joins its contained services and yields the atomic service M. This activity is
necessary because the final goal requires a contained atomic service.
Step 3. The analysis solution proposition is finally achieved by aggregating the atomic service
M into the composite service A, as depicted in Exhibit 7.24. The aggregation operation
simply binds these services and creates a parent-child type of relationship.

DELIVERABLES
The service discovery and analysis deliverable model is made up of two major artifacts that
should be submitted when the analysis process comes to fruition. It is imperative to iterate on the
previously discussed analysis activities and refine the final analysis solution proposition. These
artifacts should enrich service life cycle strategy foundation and should be utilized to define
the essence of the services for impending design, architecture, construction, and deployment
projects.
