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.

A TOGAF business scenario is a technique that helps to derive architecture requirements by describing a business process, application, or set of activities. It includes detailing the actors, roles, goals, business policies, business processes, and the environment in which the scenario takes place. Business scenarios are used within TOGAF to ensure that the architecture has a clear link to the business requirements.

 A key principle of value streams is that value is always defined from the perspective of the stakeholder2. A stakeholder is any person or group who has an interest in or influence on an enterprise or its activities5. A stakeholder can be internal or external to the enterprise. A stakeholder can also be a customer, end user, partner, supplier, regulator, employee, or any other role that interacts with or benefits from the enterprise’s products or services5. Value streams should reflect how stakeholders perceive and measure value in terms of outcomes, benefits, costs, risks, and satisfaction2.

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.

In TOGAF's ADM, the development of architecture is an iterative process. During Phase A, initial business capability maps and value streams are created to establish the Architecture Vision. However, as stakeholders provide more detailed inputs and requirements are refined, it is necessary to update the Architecture Descriptions. This is an iterative process that continues into Phase B, Business Architecture, where these descriptions are further developed and refined.

 The process used to decompose a set of business capabilities to communicate more detail is leveling6. Leveling is a technique that can be used to break down a business capability into sub-capabilities at lower levels of granularity6. Leveling can help to provide more clarity and specificity about what a business capability entails and how it supports the business goals and objectives6. Leveling can also help to identify dependencies, gaps, overlaps, or redundancies among business capabilities6.
