A TOGAF business scenario is a technique that can be used to fully understand the requirements of information technology and align it with business needs1.It is not a business case, which is a document that provides justification for a proposed project or initiative6.It is not a method to develop a business model, which is a description of how an organization creates, delivers, and captures value for its stakeholders7. It is not a use-case, which is a description of how a system interacts with external actors to achieve a specific goal.

The development of Business Architecture Descriptions is always iterative because it involves constant refinement and validation of the architecture models and views based on stakeholder feedback and changing requirements. Therefore, any Architecture Description that was created in Phase A may need to be updated in Phase B as new information or insights emerge. Phase B does not require that all Architecture Descriptions be updated, only those that are relevant and necessary for the Business Architecture. Phase B is an ADM Architecture Development phase, but that does not explain why Architecture Descriptions need to be updated. A new value stream may or may not require updating existing Architecture Descriptions depending on its scope and impact.

Risk is defined as the effect of uncertainty on objectives. It can be positive or negative depending on whether it enhances or hinders the achievement of objectives. Threat is a potential cause of risk that could have a negative impact on objectives. Continuity is the ability to maintain or resume normal operations after a disruption or disaster. Vulnerability is a weakness or exposure that could be exploited by a threat to cause harm or damage.

The graphic illustrates a method for developing alternative target architectures in Phase E of the TOGAF ADM1.The method involves identifying and evaluating candidate architectures based on criteria such as business value, cost, risk, and feasibility1. The method helps to identify the most suitable architecture solution for the enterprise.

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.

Value networks are an approach to model, measure, and analyze business value that is primarily concerned with identifying the participants involved in creating and delivering value3.Value networks focus on the relationships and interactions among the participants, such as customers, suppliers, partners, employees, and other stakeholders3. Value networks can help to understand how value flows through the network and how it can be improved or optimized.

Business models are used within the TOGAF standard to help formulate architecture and business principles4.A business model describes how an organization creates, delivers, and captures value for its stakeholders4. A business model can help to define the strategic direction, goals, and objectives of the organization, which can then inform the development of architecture and business principles that guide the design and evolution of the enterprise architecture.

Value streams can be used to help define information concepts in an information map5.A value stream is a representation of a sequence of activities that create an overall result for a customer, stakeholder, or end user5. A value stream can help to identify the information that is required, produced, consumed, or exchanged by each activity in the value stream. An information map can then document and visualize the information concepts and their relationships.

A business model is a description of the rationale for how an organization creates, delivers, and captures value4.Value is defined as the worth or importance of something to someone6.A business model explains what value proposition the organization offers to its customers, what revenue streams it generates from delivering the value proposition, what cost structure it incurs to create and deliver the value proposition, what key resources and activities are needed to create and deliver the value proposition, and what key partnerships are leveraged to support the value creation and delivery process4.

According to the TOGAF Standard, when developing the Architecture Vision, the architect should examine and search for business capabilities and organization maps1.Business capabilities are the expression or the articulation of the capacity, materials, and expertise an organization needs in order to perform core functions2.Organization maps are a technique that can be used to show how a business architecture addresses stakeholder concerns across different parts of an organization3. These concepts can help to define the scope and objectives of the architecture project, as well as to identify key stakeholders and their needs.
