It allows direct comparison of EA artifacts in the current and future views.
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.
EA artifacts are types of documentation that describe components, including reports, diagrams, charts, spreadsheets, video files, and other types of recorded information. High-level EA artifacts are often text documents or diagrams that describe overall strategies, programs, and desired outcomes. Mid-level EA artifacts are documents, diagrams, charts, spreadsheets, and briefings that describe organizational processes, ongoing projects,… Continue reading What are EA artifacts and how do they relate to EA components?
Because business processes change and/or are replaced over time. An enterprise’s key business and support processes are documented at the Business level of the EA framework. EA components at this level include business process documentation and an IT capital planning portfolio that provides business case documentation on each investment in IT that meets operational and… Continue reading Why can an enterprise’s business processes be viewed as EA components?
Because information flows and data objects change and/or are replaced over time. How an enterprise uses data and information is documented at the Data and Information level of the EA3 Cube Framework. \nEA components at this level include documentation on the design, function, and management of information systems, databases, knowledge warehouses, and data marts. It… Continue reading Why can an enterprise’s information flows and data objects be viewed as EA components?
Because software applications and networks change and/or are replaced over time. The systems and applications that an enterprise uses to support its business services, product delivery processes, and information flows are documented at the Systems and Applications level of the EA3 Framework. One of the purposes of EA is to improve the integration and efficiency… Continue reading Why can an enterprise’s software applications and networks be viewed as EA components?
Open standards at the national and international level promote EA component interoperability.
IT security related processes, information flows, applications, systems, and network hardware and software.
The current view of the EA is intended to show the IT resources that are presently active in the enterprise’s IT operating environment. This is also known as the as-is view of the EA. Depending on the amount of prior EA planning, these IT resources may or may not be aligned with the enterprise’s strategic… Continue reading What is the purpose of current views of EA components?
EA artifacts document EA components in a consistent way across the entire architecture.
