What distinguishes Business Architecture from Enterprise Architecture?

The distinction between Business Architecture and Enterprise Architecture is crucial in understanding their respective scopes and focuses. Business Architecture is primarily concerned with the organization's business processes, capabilities, and overall operations. It aims to model how organizational structure and business functionality align with strategic objectives, shedding light on key elements such as organizational roles, business capabilities, and process management.

In contrast, Enterprise Architecture has a broader perspective, encompassing not only business processes but also IT infrastructure, systems, applications, and technology alignment. It serves to ensure that the entire enterprise, including its architecture components—both business and technological—functions cohesively to achieve business goals.

This answer highlights the specific focus of Business Architecture on the processes and capabilities that drive business success, separating it from the wider view taken by Enterprise Architecture, which includes technology and systems considerations. Understanding this distinction helps clarify the roles and responsibilities associated with each architecture, facilitating better alignment of business strategies with technology solutions.
