The Open Group Architecture FrameworkIntroductionOver the last 30 years enterprise architectural methodologies or frameworks have been developed but four have emerged as the top methodologies. One of those top four methodologiesis The Open Group Architecture Framework (TOGAF). In 1995, TOGAF was developed from the U.S Department of Defense Technical Architecture Framework for Information Management (TAFIM). Since its development TOGAF has become one of if not the most prominent and reliable enterprise architecture standards in the world. As of 2015, 80% of the Global 50 companies and 60% of Fortune 500 companies use TOGAF to improve business efficiency (TheOpen Group, 2015). Where the Zachman framework is the ontology for EA, TOGAF is the methodology. Purpose of The Open Group Architecture FrameworkThe purpose of The Open Group Architecture Framework is like any other framework, which is to enable the delivery of the enterprise architecture. The ISO/IEC 42010:2007 defines “architecture” as: The fundamental organization of a system, embodied in its components, their relationships to each other and the environment, the principles governing its design and evolution(Josey, 2011). In other words TOGAF’s purpose is to provide the methods and tools to assist in the development acceptance, production, use and maintenance of an enterprise architecture (Josey, 2011).Scope of The Open Group Architecture FrameworkWhen TOGAF was first created it only focused on technical architectures; only recently has the business architecture domain been included in its focus. The inclusion of the business 2

Today, TOGAF’s architecture domains include: Business Architecture, Application Architecture, Data Architecture, and Technical Architecture (Sessions, 2007). With its beginnings in technical architecture TOGAF continues to win support from the technical community. Principles of The Open Group Architecture FrameworkWhile the Zachman Framework can be considered a “architectural taxonomy” telling youhow to categorize the components of an EA, TOGAF establishes a process for how to create the
