Business architecture is a discipline that represents and designs the holistic organizational structure, business processes, information flows, and technological infrastructure.
It serves as a strategic framework, bridging the gap between an organization's vision and its tangible operations. It aligns all parts of the organization with its goals and objectives by providing a clear map.
Business architecture is one of the pillars of the broader discipline of enterprise architecture.
Business architecture vs. enterprise architecture: While both are concerned with alignment and coherence, business architecture focuses in on the business strategy and its translation into operational reality. Enterprise architecture, on the other hand, covers the entire spectrum, including IT architecture, and technology architecture.
Business architecture vs. solution architecture: Solution architecture is more IT-centric, focusing on designing solutions to specific business problems, often involving the integration of technology. Business architecture, meanwhile, provides the broader context within which these solutions are designed.
Business architecture vs. IT architecture: Business architecture and IT architecture are intertwined disciplines steering an organization towards its goals. Business architecture visualizes relationships between business entities and processes. Conversely, IT architecture centers on the technological infrastructure, ensuring a secure and efficient environment that supports business goals.
Business architecture and business analysis: Business analysis is about identifying business needs and finding technical solutions to business problems. Business architecture provides the strategic context for these analyses, ensuring that solutions align with the company's broader objectives.
