EA Framework Research Paper
Introduction
An Enterprise Architecture Framework (EAF) provides principles and practices for creating and using the architecture description of a system. Frameworks are used to help organizations answer specific question. Enterprise Architecture framework importance is de-emphasized deliberately sometimes. Without a framework though, it is impossible to have foreseeable and repeatable outcomes. There are many EA frameworks out there. However, the four leading ones are The Zachman Framework for Enterprise Architecture, The Open Group Architecture Framework (TOFAF), Federal Enterprise Architecture, and Gartner Enterprise Architecture Framework. These methodologies are quite different from each other, both in goals and in approach. Many organizations use a blend of these methodologies to find a great framework for the goals they are trying to accomplish. The Enterprise Architecture framework I will be covering is Zachman Framework. I choose this framework due to it being the one all other framework are compared too. John Zachman's framework for information systems architecture has been widely discussed since its publication in the IBM Systems Journal in 1987(Evernden,1999) .
Description of Zachman Framework
Zachman Framework was first introduced in 1987, and was extend in 1992. Zachman Framework was called Information System Architecture Framework in the early years (Fatolahi,2006). The Zachman Framework has evolved over time. Although the framework structure still remains the same, it has changed on the graphical representations to gain more generalization and logical representation. Zachman Framework is considered to be the most referenced framework on Enterprise Architecture. Zachman Framework is always being compared with other frameworks to justify if they are correct and can be used. According to Schekkman(2003), 20 percent of Enterprise Architectures
