Enterprise Architecture (EA)
Enterprise Architecture is a method of transforming business vision and approach into useful enterprise modification by creating, communicating and improving the key requirements, principles and models that define the enterprise’s future state and empower its progress. The main goal of EAis effectiveness, efficiency, agility and durability of the enterprise. However, the MIT Center for Information Systems Research (MIT CISR) defines enterprise architecture as the specific aspects of a business as,
“ Enterprise architecture is the organizing logic for business process and IT infrastructure reflecting the integration and standardization requirements of the company’s operating model. The operating model is the desired state of business process integration and business process standardization for delivering goods and services to customers.”
Specialists of the EA are called as enterprise architects. An enterprise architect is accountable for carrying out this complex study of business structure and process and is often called upon to draw conclusions from the information collected. An enterprise can be recognized as a public or private sector organization, an entire business or corporation, a part of a large enterprise, a multiply outsourced business operation. Moreover, the term “enterprise” includes the whole complex, socio -technical system such as people, information, technology and business. A realistic EA provides a context and a scope. The context involves people, organizations, systems and technology out of scope that have interactions with the organizations, systems and technology scope. In exercise, the architect is in charge for the articulation of the scope context, engineers are accountable for the details of the scope. The architect are still responsible for the work of the engineers, and executing contractors afterwards.
