Business Scenarios and Business Models are tools that architects can present to stakeholders to facilitate discussions that reveal underlying assumptions, agendas, principles, and requirements. They help in understanding the context, extracting and validating requirements, and identifying potential impacts on the target architecture. By discussing scenarios and models, stakeholders can express their vision and concerns, which may include unspoken or implicit needs that are crucial for the architecture's success.

According to the TOGAF standard, business models are used to understand and describe the business itself, including its organization, its objectives, and how it operates. This understanding is crucial when defining an enterprise architecture as it provides a frame of reference. Business models help in identifying new capabilities that the business must develop to achieve its future state as outlined in the target business model. These capabilities may be processes, information, or technologies that the business must adopt or adapt to fulfill the strategic objectives and deliver value. TOGAF emphasizes the alignment of IT with business strategy, and the business model serves as a key link in ensuring that the capabilities delivered by the enterprise architecture will enable the desired business outcomes.

In the TOGAF ADM cycle, Phase A, the Architecture Vision phase, is where the architect would locate existing architecture descriptions to create an information map. This phase involves understanding the strategic context for the architecture work, defining the scope, identifying stakeholders, creating the Architecture Vision, and obtaining approvals to proceed with the work. Part of this involves reviewing existing documentation to understand the current state of the architecture and the information that is already available, which would be useful for creating an information map.

In the absence of existing Architecture Descriptions, the development of a Business Architecture would begin with the gathering of relevant information about the business. This information can come from strategic documents, business plans, process documents, and stakeholder interviews, among other sources. Once gathered, this information would be used to create Business Architecture models that articulate the business vision, strategy, governance, organization, and key business processes. These models provide a blueprint that captures the essence of the business and guides subsequent architecture work.

The technique shown in the example is called relationship mapping. It is a technique that can be used to show how a business architecture addresses stakeholder concerns across different parts of an organization2. It can highlight gaps or overlaps in the coverage of stakeholder concerns by a business architecture. In this case, the technique is used to relate business capabilities to organization units so as to highlight duplication and redundancy.
This modeling technique is referred to as Relationship Mapping. It's used to relate business capabilities to organizational units to highlight areas of duplication and redundancy, as well as to indicate where capabilities are being performed well (green), where there are potential issues (yellow), and where there are significant problems or gaps (red). This visualization helps in understanding the alignment between organizational units and capabilities, and where improvements or changes may be needed.
