This scenario requires selecting appropriate viewpoints (represented by catalogs, matrices, and diagrams) for an iterative architecture development process. The key is to address the specific stakeholder concerns in a logical sequence. A "Target-first" approach is often effective in transformation projects like this, as it establishes the future-state vision early on, preventing analysis paralysis on the current state.

Option B proposes a Target-first approach. In the early iterations, it focuses on defining the Target Architecture, which directly addresses stakeholder concerns about integration (Application Communication diagrams), data sharing (System/Data matrix), business object lifecycles (Product Lifecycle diagrams), and future business operations (Business Service/Function catalog). In later iterations, it develops the Baseline Architecture to understand the current state (concerns #1, #2, #3) using artifacts like the System/Organization and System/Function matrices, which is essential for gap analysis and migration planning. This sequence and choice of artifacts provide the most comprehensive and logical approach to addressing all stated concerns.

A: This option proposes a "Baseline-first" approach and includes a Technology Portfolio catalog for the Application Architecture, which is less appropriate than an application-focused artifact. The Actor/Process/Data catalog is not a standard TOGAF artifact.

C: While also a "Target-first" approach, it suggests an "Application and User Location diagram" for the Baseline. The scenario has no stated concerns about geographic location, making this artifact less relevant than those in option B.

D: This option follows a "Baseline-first" approach, which can be less effective for a major transformation. It is also less comprehensive, as it omits a specific artifact to address the business object lifecycle concern.

Section 35.3

Architecture Viewpoints. This section describes the various viewpoints and their purposes. The artifacts listed in option B (e.g.

Business Interaction Matrix

Application Communication Diagram

System/Data Matrix) are standard TOGAF viewpoints used to address stakeholder concerns like those in the scenario.

Iteration and the ADM. This section explains that the ADM is iterative

both across the whole process and within phases. It states

"At the beginning of an iteration

the architect will select the viewpoints that are relevant to the current iteration." Option B demonstrates a logical selection of viewpoints for distinct iterations (early Target

later Baseline).

and Diagram Types. This section details the specific artifacts. For example

the Product Lifecycle Diagram (a type of Data Lifecycle Diagram) is ideal for concern #4. The System/Function Matrix is designed to show the relationship between applications and business functions (concern #3). The Application Communication Diagram addresses integration (concern #5).
