e-Business architecture

A business architecture is an organizing framework of a business, and the documents and diagrams that describe that structure or the people who help build such a structure, respectively.
Business architecture is close related to concepts enterprise architecture and business reference model.The term "Business Architecture" is used to refer to a process, model or profession. A formal definition of the first meaning is defined by the Object Management Group's Business Architecture Working Group as follows:[1]
"A blueprint of the enterprise that provides a common understanding of the organization and is used to align strategic objectives and tactical demands.”
Business Architecture articulates the structure of an enterprise in terms of its capabilities, governance structure, business processes, and business information.[2] The business capability is "what" the organization does, the business processes, are "how" the organization executes its capabilities. In articulating the governance and information,the business architecture considers all external actors to an enterprise (including its customers, suppliers, and regulators), to ensure that flow in and out of the enterprise are captured.
