The TOGAF framework emphasizes that effective communication with stakeholders is crucial for the success of an architecture project. Architecture Views and Viewpoints are the primary mechanisms for this communication. A viewpoint defines the perspective and conventions for constructing a view (e.g., a security viewpoint). A view is the actual representation of the architecture presented to a stakeholder to address their specific concerns (e.g., a diagram showing data flows and security controls). By presenting different views, tailored to different stakeholder viewpoints, architects can ensure the architecture is understood and validated, which is essential for eliciting feedback and uncovering previously unstated requirements, principles, or hidden agendas.

A. Alternatives, Trade-offs: While presenting alternatives and their trade-offs is an important activity, it is a specific technique often facilitated through architecture views, not a replacement for them.

B. Solutions, Applications: These terms are too specific. "Solutions" are addressed in later ADM phases, and "applications" are only one component of an architecture. This pair does not represent the fundamental communication concept.

D. Business Scenarios, Business Models: Business Scenarios are a technique used to elicit and document requirements, which then drive the architecture work, rather than a method for presenting the architecture to get feedback.

Architecture Views and Viewpoints: This chapter states

"The concept of views and viewpoints is fundamental to the TOGAF Architecture Framework... A view is what you see. A viewpoint is where you are looking from – the perspective that determines what you see." This highlights their role in tailoring communication.

Stakeholder Management

Section 22.4: "The architect must identify the key stakeholders and their concerns/objectives

and define key views that will be used to communicate the architecture to them." This directly links the use of views to addressing stakeholder concerns

which is the process that uncovers hidden requirements.

Core Concepts

Definitions 3.30 and 3.31: Defines an Architecture View as "a representation of a system from the perspective of a related set of concerns" and an Architecture Viewpoint as "a specification of the conventions for a particular kind of architecture view". This confirms that presenting different views from different viewpoints is the formal method for addressing varied stakeholder concerns.
