OGEA-101 Exam Results

This statement best describes iteration and the ADM. The ADM is iterative over the whole process between phases and within phases because it allows for feedback loops and refinements at any point in the architecture development and transition process. Iterationenables architects to address changing requirements, assumptions, constraints, and environments; to validate and improve architectures; to manage risks and issues; and to ensure stakeholder satisfaction and value realization. Reference: The TOGAF® Standard | The Open Group Website, Section 3.1 Introduction to the ADM.

According to the TOGAF standard, the objectives of each ADM phase are as follows1:

•Phase E: Opportunities and Solutions

oDetermine whether an incremental approach is required, and if so identify Transition Architectures that will deliver continuous business value

oIdentify and group major work packages within the Architecture Roadmap

oIdentify and group major implementation projects to realize the Architecture Roadmap

oIdentify dependencies between increments and projects

oEstimate cost, benefit, and risk at a high level for each increment and project

oConduct initial prioritization and sequencing of the Architecture Roadmap and projects

•Phase F: Migration Planning

oGenerate the initial complete version of the Architecture Roadmap, based upon the gap analysis and candidate Architecture Roadmap components from Phases B, C, and D

oConfirm the Transition Architectures with relevant stakeholders

oCreate the Implementation and Migration Plan, including Transition Architectures, work packages, projects, and other activities

oConfirm and agree the Architecture Roadmap and Implementation and Migration Plan with relevant stakeholders

•Phase G: Implementation Governance

oFinalize the Architecture Roadmap and the supporting Implementation and Migration Plan

oEnsure conformance with the Target Architecture by implementation projects

oPerform appropriate Architecture Governance functions for the solution and any implementation-driven architecture Change Requests

oEnsure that the architecture lifecycle is maintained

oEnsure that the Architecture Governance Framework is executed

•Phase H: Architecture Change Management

oEnsure that the business value and cost of work packages and Transition Architectures is understood by key stakeholders

oManage risks and issues related to the Architecture Roadmap and Implementation and Migration Plan

oMonitor the implementation projects and Transition Architectures

oManage changes to the architecture baseline

oManage changes to the Architecture Capability

Therefore, the correct matching of the objectives and the phases is:

•1G: Determine whether an incremental approach is required, and if so identify Transition Architectures that will deliver continuous business value

•2E: Generate the initial complete version of the Architecture Roadmap, based upon the gap analysis and candidate Architecture Roadmap components from Phases B, C, and D

•3F: Finalize the Architecture Roadmap and the supporting Implementation and Migration Plan

•4F: Ensure that the business value and cost of work packages and Transition Architectures is understood by key stakeholders

The scope of an architecture is the extent and level of detail of the architecture work. The scope of an architecture can be defined along four dimensions: project, breadth, depth, and architecture domains. The project dimension considers the boundaries and objectives of the architecture project, such as the time frame, budget, resources, and deliverables. The breadth dimension considers the coverage and completeness of the architecture across the enterprise, such as the organizational units, business functions, processes, and locations. The depth dimension considers the level of detail and specificity of the architecture, such as the granularity, abstraction, and precision of the architectural elements and relationships. The architecture domains dimension considers the aspects or segments of the architecture, such as the business, data, application, and technology domains.

Therefore, the depth dimension is the one that considers to what level of detail the architecting effort should go.

• According to the TOGAF Standard, Version 9.2, an architecture view is a representation of a system from the perspective of a related set of concerns1. It consists of one or more architecture models that demonstrate how the system addresses the stakeholder concerns1.
• An architecture viewpoint is a specification of the conventions for constructing and using an architecture view to address specific stakeholder concerns1. It defines the perspective, scope, notation, and techniques for creating an architecture view of a system1.
• Architects can present architecture views and viewpoints to stakeholders to extract hidden agendas, principles, and requirements that could impact the final Target Architecture, because23:
