TOGAF® Standard—Arc hitecture Development Method Flashcards
What is the TOGAF ADM?
The Architecture Development Method (ADM) is a step-by-step approach to developing and managing an Enterprise Architecture (EA). It helps organizations structure their architecture development process effectively.
What are the key phases of the TOGAF ADM?
The ADM consists of the following phases:
Preliminary
A (Architecture Vision)
B (Business Architecture)
C (Information Systems Architecture - Data & Application)
D (Technology Architecture)
E (Opportunities & Solutions)
F (Migration Planning)
G (Implementation Governance)
H (Architecture Change Management)
Requirements Management (Ongoing)
Each phase plays a crucial role in ensuring a comprehensive architecture strategy.
What is the purpose of the Preliminary Phase?
To establish the Architecture Capability, governance, and framework within the organization, and align architecture with business strategies. This ensures a solid foundation for further architectural work.
What is the main objective of Phase A (Architecture Vision)?
To define the scope, purpose, and high-level vision of the architecture effort while identifying stakeholders and business goals. This phase sets the direction for the entire ADM cycle.
What is developed in Phase B (Business Architecture)?
The Baseline and Target Business Architectures, including capabilities, processes, functions, and a transformation strategy. It helps align IT with business goals.
What are the two parts of Phase C (Information Systems Architectures)?
Data Architecture (defining data models and governance) and Application Architecture (identifying business applications and their interactions). These ensure effective data management and application integration.
What is the focus of Phase D (Technology Architecture)?
Defining the IT infrastructure, including hardware, software, and networks, as well as identifying gaps and developing roadmaps. This ensures a robust technological foundation.
What happens in Phase E (Opportunities & Solutions)?
Reviewing gap analysis results, developing the architecture roadmap, and identifying work packages for transition. This phase bridges the gap between design and implementation.
What is the goal of Phase F (Migration Planning)?
Prioritizing and sequencing implementation projects and developing a migration plan. This ensures a smooth transition to the target architecture.
What does Phase G (Implementation Governance) ensure?
That the architecture is correctly implemented through compliance reviews and governance processes. This helps maintain consistency and alignment with business goals.
What is the purpose of Phase H (Architecture Change Management)?
To establish continuous improvement, risk management, and value realization for the architecture. This phase ensures adaptability to changing business needs.
What is the function of Requirements Management in ADM?
Ensuring that business and IT requirements are continuously tracked and integrated into all phases. This keeps the architecture relevant and up to date.
What is the Enterprise Continuum?
A classification framework for organizing architecture assets, including reference models and best practices. It helps in reusing existing architecture elements.
What is the Architecture Repository?
A storage system for reusable models, principles, frameworks, and architecture work products. It acts as a knowledge base for enterprise architects.
What are the four dimensions used to scope an architecture?
Breadth (extent of business areas covered), Depth (level of detail), Time Period (transition phases), and Architecture Domains (Business, Data, Application, Technology). These help in defining the architecture effort.
Why is governance important in TOGAF ADM?
Governance ensures compliance with architecture principles, standards, and best practices, and maintains alignment with business goals. It provides accountability and control.
What are Architecture Principles?
Guidelines that influence architecture decisions, including Business Principles, Technology Standards, and Data Management Policies. They ensure consistency in decision-making.
How can organizations adapt the TOGAF ADM?
By tailoring terminology, process steps, and integrating with existing frameworks (e.g., ITIL, Zachman) to fit organizational needs. This customization enhances its effectiveness.
What is an Architecture Vision document?
A high-level representation of the desired architecture, outlining scope, goals, and stakeholder concerns. It serves as a guiding document.
What is the difference between Baseline and Target Architectures?
Baseline Architecture represents the current state, while Target Architecture defines the future desired state. This helps in planning the transition.
What is the purpose of Gap Analysis in ADM?
To identify differences between Baseline and Target Architectures and determine necessary changes. This ensures alignment with business goals.
What is a Transition Architecture?
An intermediate stage that enables the enterprise to evolve from the Baseline to the Target Architecture incrementally. It provides a structured approach to transformation.
How does TOGAF ADM support iterative development?
By allowing repeated cycles of architecture refinement, incorporating feedback, and adjusting scope and details as needed. This ensures continuous improvement.
What is the Architecture Roadmap?
A plan that outlines the sequence of projects and initiatives required to achieve the Target Architecture. It provides a structured path for implementation.
