The Open Group OGEA-103 - TOGAF Enterprise Architecture Combined Part 1 and Part 2 Exam

A business scenario describes business and technology environment in which those problems occur. It provides a realistic context for identifying and addressing business problems and opportunities, as well as their impact on the enterprise’s architecture. Reference: The TOGAF® Standard | The Open Group Website, Section 3.3.1 Business Scenarios.

In TOGAF’s ADM, the Request for Architecture Work is the deliverable issued by the sponsoring organization (or stakeholder) to formally request that the architecture team perform a full architecture development cycle. That corresponds to your “deliverable 3.” Then, the architecture team responds by producing a Statement of Architecture Work (in Phase A), which defines the scope, constraints, approach, and highlevel tasks for the architecture development. That is your “deliverable 4” (the scope and approach). Thus deliverable 3 is the Request for Architecture Work, and deliverable 4 is generated in Phase A. The Request triggers the cycle; the Statement of Architecture Work (in Phase A) lays down how the architecture work will proceed, including scoping and approach.

When scoping an architecture in TOGAF, three key axes (dimensions) are used to frame the extent of the architecture work. The first is time period (how far into the future or over what timeframe to plan). The second is depth—how detailed or granular the architecture models will be (e.g., high level, mid level, very detailed). The third is breadth, which refers to which parts (domains, business units, functions) of the enterprise will be included, and which architecture domains (business, data, application, technology) will be in scope. This triple‐dimension model helps architects, stakeholders, and governance bodies understand how wide, deep, and forwardlooking the architecture effort will be. Thus “breadth, architecture domains” is the correct third dimension.
