The service alignment should follow next. Integrate services with these defined perspectives,
rather than with the business domains themselves. The process by which the perspectives
of a domain are denoted is simple: Exhibit 11.20 illustrates a scenario by which business domain
D1 is depicted along with its two associated perspectives: the strategy contextual perspective and
the tactical contextual perspective.

EXHIBIT 11.21 SERVICE INTEGRATION WITH CONTEXTUAL PERSPECTIVES
228 Ch. 11 Service-Oriented Business Integration Modeling
Exhibit 11.21 illustrates more complex service-oriented business integration. This depicted
scenario exemplifies the process by which services are aligned with two contextual perspectives
of the loan division domain (D1), rather than directly being integrated with it. Note that the
core product perspective (P1) is integrated with the CM1 composite service, and the management
perspective (P2) is aligned with the atomic service A1 and the service cluster CL1.
