BUSINESS ARCHITECTURE PERSPECTIVES AS CATEGORIZATION MECHANISMS. Most serviceoriented
and legacy technical architectures in an organization are byproducts of business ideas
and strategies. These architectures are funded and developed because of enterprise necessities and
are shaped by business models. Service-oriented and legacy technical architectures that do not
have the backing of business organizations or have not originated from business requirements are
rare. Thus, a business organization that supports an architecture??™s construction, operations, and
sponsors its enhancements also ought to assess its value to the enterprise.
