So how can a business organization categorize
the various service-oriented and legacy technical architectures?We should employ service-oriented
business architecture perspectives to facilitate the establishment of business views that can enable
categorization and fiscal evaluations. Families of technical architectures should match their corresponding
business architecture perspectives in terms of their business context and requirements.
Exhibit P.2 exemplifies a business architecture perspective along with its corresponding
architecture group. This grouping method is straightforward. The core products business architecture
perspective (contextual view) is associated with three major technical architectures that
support the core products of this particular organization: mutual funds trading technical architecture,
equity trading technical architecture, and the fixed-income trading technical architecture.
Finally, the categorization effort of the organization??™s technical architectures??”facilitated
by the business architecture perspectives??”offers a detailed map of the most vital technical
architectures in the enterprise. This classification framework can assist with a more accurate
service-oriented business alignment with various business architectural perspectives.
PERSPECTIVES ENABLE ALIGNMENT WITH BUSINESS PRIORITIES. Business organizations typically
support multiple technical architectures that promote their business execution.
