• Question 111:

  Consider the diagram of an architecture development cycle.

  

  Which description matches the phase of the ADM labeled as item 2?

  A. Conducts Implementation planning for the architecture defined in previous phases
  B. Provides architectural oversight for the implementation
  C. Operates the process of managing architecture requirements
  D. Establishes procedures for managing change to the new architecture
  B. Provides architectural oversight for the implementation

  ---

  Explanation

  The Architecture Development Method (ADM) is the core process of TOGAF which outlines a method for developing and managing the lifecycle of enterprise architecture. Considering the phases of the ADM, the item labeled as '2' in the provided architecture development cycle diagram likely corresponds to the 'Architecture Change Management' phase, which is responsible for providing ongoing architectural oversight and guidance to ensure that the implementation remains aligned with the architecture defined in the previous phases. This includes managing changes to the architecture in a controlled manner as the implementation progresses and ensuring that the architecture continues to meet the business needs.

• Question 112:

  Which of the following best describes a benefit of business models?

  A. They provide a different viewpoint to cross-check assumptions.
  B. They can be used to resolve conflicts amongst different stakeholders.
  C. They can be used to calculate detailed cost estimates.
  D. They highlight what the business does without the need to explain why.
  A. They provide a different viewpoint to cross-check assumptions.

  Explanation

  Business models are essential tools within TOGAF for providing different perspectives on the business operations, strategies, and value propositions. Here's a detailed explanation:

  Purpose of Business Models:

  Business models are designed to represent various aspects of the business, such as value creation, delivery, and capture mechanisms. They provide a structured way to analyze and understand the business.

  Different Viewpoint:

  Cross-Check Assumptions: Business models offer a different viewpoint that helps in validating and cross-checking assumptions made about the business. By presenting a visual and structured representation of the business, these models

  enable stakeholders to identify gaps, inconsistencies, and areas that need further analysis.

  Holistic Understanding: They help in gaining a holistic understanding of how different components of the business interact, which is crucial for ensuring that the enterprise architecture aligns with the business strategy and goals.

  Phase A: Architecture Vision: During this phase, business models are used to articulate the vision and scope of the architecture effort. They help in ensuring that all assumptions are validated and that the architecture aligns with business

  objectives.

  Phase B: Business Architecture: Business models are also utilized in this phase to analyze business capabilities, processes, and value streams. They provide a different viewpoint that aids in identifying areas for improvement and ensuring

  alignment with the strategic intent.

  In summary, business models provide a different viewpoint that helps cross-check assumptions, ensuring that the enterprise architecture is aligned with the business strategy and objectives.
