Business Architecture defines the structure of the enterprise in terms of its governance, business processes, and business information. In defining the structure of the enterprise, business architecture considers customers, finances, and the ever-changing market to align strategic goals and objectives with decisions regarding products and services, partners and suppliers, organization, capabilities, and key initiatives.
It focuses primarily on business motivations, operations and is fueled by business analysis frameworks that network into those aspects of the enterprise.
In order to develop an integrated view of an enterprise, many different views of an organization are typically developed. The key views of the enterprise within the business architecture are:
The Business Strategy view captures the strategic goals and tactics that drive an organization forward. The goals are aligned to tactical efforts which provide traceability and accountability based on metrics that measure ongoing success in achieving the goals.
The Business Capabilities view describes the primary business functions of the enterprise and the business units that perform those functions. This view further distinguishes between customer-facing functions, supplier-related functions, business execution, and business management.
The Value Stream view sets the end-to-end activities that deliver value to external and internal stakeholders which often transcend organizational boundaries. Value streams are the lenses that view the business “in motion” and are a key aspect of business architecture.
The Business Knowledge view establishes a shared understanding of business semantics (i.e., customer, order, and supplier) and the relationships between those them such as customer name, order date, supplier name, etc. These semantic definitions form the vocabulary that the organization relies on to communicate among the areas they operate within.
The Organizational view captures the relationships across roles, capabilities and business units and the internal or external management of those units.
The cumulative relationships and connections across these enterprise view are the foundational framework of the business architecture that supports the achievement of key goals and inform planning and execution of business scenarios and ultimately the delivery of bottom line business value.
