An integrated set security and privacy controls for the enterprise is created by including these considerations security in the planning, design, implementation, and operation of all EA components and artifacts. For information-centric enterprises, including IT security and data privacy as required design elements of EA components, and having leadership support at the strategic and line… Continue reading How does IT security functions at each level of the EA3 framework?
The framework should identify the areas of the enterprise that the EA will cover, and how those areas relate. For example, the EA3 framework identifies five functional areas and three ‘thread’ areas to be documented, organizes different types of components, and then orients the components into lines of business. These relationships are important in conveying… Continue reading What is the role of an EA framework within the EA methodology?
Analysis and documentation, as organized through an EA framework, provides standardized, hierarchical views of the enterprise from an integrated strategy, business, and technology perspective
The EA framework defines what the EA program will document, and the EA methodology defines how that documentation will be developed and used. By defining what parts of the enterprise are included in the EA, the framework defines the scope of the architecture. The design of the framework communicates the relationship of the areas of… Continue reading What are some of the basic characteristics of an EA framework?
The five levels of the EA3 Framework are hierarchical and integrated so that separate sub-architectures are not needed to reflect different levels or functional areas of the enterprise. The architectural areas covered at each level are arranged to position high-level strategic goals at the top, general business services and information flows in the middle, and… Continue reading Why are hierarchical levels of an EA framework helpful in documenting an enterprise?
Spewak states that EAP is a method for developing the top two levels of Zachman’s Framework.
While an EA framework provides an overall structure for modeling the enterprise’s business and technology operating environment, EA components are the working elements of the framework at each level. In other words, EA components are building blocks that create discrete parts of the overall IT operational capability. EA artifacts describe EA components.

The Integration Definition for Function, or IDEF technique. Developed in the mid-1970’s for modeling complex military projects, IDEF-0 uses Inputs, Outputs, Controls and Mechanisms (ICOM) to show the parts of an activity within an enterprise. IDEF-0 activity modeling is suitable for business process documentation in that it provides both high level context views, and more… Continue reading What is the IDEF-0 modeling technique and how can it be used to document EA components at the Business Level of the EA3 framework?
