COMBINING SERVICE ANALYSIS METHODS
The proposed service analysis operations should be repeated and combined until the business
or technical requirements are satisfied. It is imperative to iterate on these analysis practices to
perfect the final artifacts before moving on to the analysis modeling process (discussed in Chapter
8). The implementation method is simple. After each logical operation, evaluate the intermediate
results to ensure that the efforts made are aligned with the service analysis solution propositions.

EXHIBIT 7.21 ANALYSIS MISSION
Exhibit 7.21 illustrates the source services selected to take part in this process. The solution,
depicted in the right-hand column, represents the final results to be achieved. As shown, the
mission here is to transform composite service M to an atomic service and swap it with composite
service C.
This goal can be accomplished by a three-step service analysis operation:
Step 1. Exhibit 7.22 exemplifies the analysis subtraction operation. This step is designed to
eliminate the composite service C, since its contribution is no longer required. The
