A high cohesion of business and information needed to operate the business provide the fundamental basis for approaching Enterprise Architecture (EA) development. The aim of the Business Information Architecture (BIA) presented in this paper is to support the development of holistic information management principles in geographically dispersed environments. BIA contributes as a shared mechanism to support business information based strategic and operational thinking, forcing isolated business units to become aware of, understand, structure, and present local business critical information using ontologies and communication genres to aid EA development, implementation, and management to support business objectives.
