What is Enterprise Architecture?

Enterprise architecture is a comprehensive framework used to manage and align an organization's business processes, information technology (IT) software and hardware, local and wide area networks, people, operations, and projects with the organization's overall strategy. A strong enterprise architecture process helps to answer basic questions such as what are the organization's business processes and how is IT supporting those processes.

What is Enterprise Business Architecture?
 

The enterprise business architecture (EBA) defines the formal link between the enterprise business strategy and the results predicted from supporting strategic initiatives. The EBA provides a single source and comprehensive repository of knowledge from which corporate initiatives will evolve and link. The evolution occurs from a fully integrated enterprise model of the business to all IT, organizational, and security architectures. The EBA also provides integration capabilities for software development, packaged software configuration, and process improvement initiatives.

By using the EBA, enterprises can formally engineer solutions that directly link to the desired results defined by the enterprise strategy. These are not seat-of-the-pants-type business projects, but instead they are business by design.
