QuestionQ36

The TOGAF Standard, Version 9.2

Based on the TOGAF standard, which of the following is the most appropriate answer?

  • A You propose that the focus be placed on architecture definition, with emphasis on understanding the strategic change parameters. The requirements, drivers, issues, and constraint for this engagement can then be identified. You would ensure that the target architecture addresses non-functional requirements so as to ensure the target architecture is robust and secure.
  • B You propose that the target architecture is defined first by going through the architecture definition phases (B-D). This is because the initial study identified the need to change. This will ensure that the change can be defined in a structured manner and address the requirements needed to realize the vision.
  • C You propose that the baseline Technology Architecture is defined first in order to assess the current infrastructure capacity and capability. Then the focus should be on transition planning and architecture deployment. This will identify requirements to ensure that the projects are sequenced in an optimal fashion so as to realize the vision.
  • D You propose that the target architecture is defined first, followed by transition planning. This is because the vision is well understood and the strategic architecture agreed. The target first approach will ensure that the current problems and inefficiencies of the baseline architecture are not carried forward, and that the proposed solution addresses the requirements identified in the initial study.
Explanation

The Target First approach is appropriate when a strategic target state has already been agreed. It develops the target architecture in detail, then assesses the baseline only as needed to identify gaps and change activities. This avoids perpetuating deficiencies from legacy systems and provides the basis for transition planning to implement the approved strategic requirements.
