Tactical Enterprise Architecture: Challenges to Building a Strategic Program

Enterprise Architecture (EA) is widely accepted as a strategic practice, focused on building a definition of future state and then managing a business and technology roadmap to help get there. The young EA program however, is often expected to contribute immediate benefits to the organization before an enterprise strategic vision or the long term roadmap has been defined. While engaged in building the solid foundations of an EA program, the Chief Architect will need to be sensitive to two distinctly different management expectations. The EA program must first be visionary, leading their management teams towards an integrated and enterprise view of business, information and technology architecture. Second, the program must also be flexible enough to manage tactical issues thrust upon them, and find ways to work those solutions into the longer term end-state architecture.

Characteristics, Roles and Responsibilities of the Modern Day Systems Architect: Lessons from the Field

The roles, responsibilities and titles of Architects often vary in relation to the domain or environment in which they operate. Throughout our work with a wide variety of clients, we have discovered that there is a „misconception‟ with regards to both the function and deliverable of the architects. This misconception often means that inappropriate resources are allocated or targeted to tasks; this can result in either delay or in appropriate solutions being delivered. In this article we discuss the roles of Enterprise, Solution and Technical Architects and highlight some key products which are produced, together with the inter dependencies between these individuals and products.

An Enterprise Abstraction Approach: Viewing Enterprise Architecture Through Natural Language Constructs

This article introduces an approach to define an Enterprise Architecture (EA) that aims to get closer to the abstraction level of the business side of an organization. Named as Enterprise Abstraction Aproach (EAA), the approach stems its roots from ontology engineering, business rules approach and business process engineering and aims to define business view of EA through natural language contructs. The approach also suggests to define domain ontology of the information view of an EA. By extending the business ontology definition towards information and technology views of EA, the approach aims to define a semantic mapping accross self-contained domain ontologies that pertain to different views of an enterprise, achieving a 360-degree view of the enterprise through a unified language.
