Business Architecture vs Enterprise Architecture

Updated Apr 04, 2021

The alignment between business architecture and enterprise architecture is a natural architectural alignment of two related disciplines. Business architecture represents a business in the absence of any IT architecture while enterprise architecture provides an overarching framework for business and IT architecture.

Business architecture is the bridge between the enterprise business model and the enterprise strategy on one side, and the business functionality of the corporate business or organization on the other side.

People who build business architecture are known as Business Architects. Working as a change agent with senior business stakeholders, the Business Architect plays a key part in shaping and fostering continuous improvement, business transformation, and business innovation initiatives.

The formal definition according to the Object Management Group's Business Architecture Working Group as follows:

"A blueprint of the enterprise that provides a common understanding of the organization and is used to align strategic objectives and tactical demands."

To increase the success of corporate initiatives, Business Architects have gained in importance within their organization to properly align all senior stakeholders in executing the business vision. Business Architecture reveals how an organization is structured and can clearly demonstrate how elements such as capabilities, processes, strategy, objectives, organization and information all fit together. The relationships among these elements dictate and specify what the organization does, and what senior stakeholders need to do to meet the organization’s common goals.
