Business Architecture Knowledgebase (BIZBOK® Guide)
This domain tests your command of the BIZBOK Guide’s structure, core terminology, blueprint categories, and the relationships that connect business architecture artifacts. Expect questions on the Business Architecture Framework, the metamodel, and how the guide positions business architecture between strategy and IT.
Framework and scope
The BIZBOK Guide frames business architecture as the discipline that bridges business strategy and IT architecture. Its framework places Business Architecture in the middle, with Business Strategy providing direction and IT Architecture realizing technology-enabled change. The guide is organized into parts covering introduction, blueprints, modeling, practice and governance, transformation, IT alignment, Agile, maturity, and case studies. Business architecture is not a project or an IT function; it is a sustained discipline for translating strategy into coordinated business change.
Blueprint categories
- Core blueprints: Capability Map, Value Stream Map, and Value Stream Cross-Mapping.
- Supporting blueprints: Organization Map, Information Map, and Business Model Canvas.
- Extending blueprints: Business Motivation Model, Strategy Map, Customer Journey Map, and Process Map.
A capability map shows what the business must be able to do. A value stream map shows how value is delivered end to end to a customer. An organization map shows who performs the work. An information map shows what information is needed.
Metamodel linkage
A capability is an ability to perform a behavior; it is not a process, function, or department. A value stream is a sequence of activities that creates value for a customer. In the metamodel, value streams are enabled by capabilities, and each value stream stage is linked to the capabilities that enable it. Capabilities decompose into sub-capabilities. Organization units have capabilities, and information concepts support capabilities.
Worked example
A question asks which blueprint best shows how a customer obtains a mortgage from application to funding. The focus is end-to-end value delivery to a customer, not organizational structure or system function. The correct answer is the Value Stream Map. If the question asks what the bank must be able to do to originate mortgages, the answer is the Capability Map. If it asks which departments perform the work, the answer is the Organization Map.
Traps that cost marks
- Treating a capability as a process or department; capabilities are stable abilities independent of org design.
- Confusing a value stream with a process; value streams are customer-centric and end-to-end.
- Assuming BIZBOK is IT-oriented; it explicitly separates business architecture from IT architecture.
- Ignoring blueprint categories; core, supporting, and extending blueprints answer different questions.
