EXHIBIT 8.7 USE CASE E??™S REQUIREMENTS
the process by which analysis services are modeled should be recorded by the analysis diagrams
that are delivered. This is imperative for all analysis efforts because it is necessary to identify the
sources of the various assets that participate in the proposed solutions. Therefore, the analysis
diagram that represents Use Case E reveals the sources C1 and C2 and further elaborates on the
swap process.
USE CASE E: COMBINED ANALYSIS MODELING OPERATIONS. A different and more complex
analysis solution proposition is required by Use Case E, shown in Exhibit 8.7. This case was
presented in Chapter 7 (in the Combining Service Analysis Methods section), which elaborates
on a three-step approach to solving an organizational concern. Here again, the problem domain
appears on the left-hand side and an analysis solution proposition is illustrated on the right. The
defined mission is to remove the composite service CO2 from its hosting composite service CO1
and replace it with the atomic service A-CO3 that is the transformation product of the composite
service CO3.
