OGA-031

The Open Group Architecture Framework (TOGAF) Standard, Version 9.2, is the basis for the OGA-031 exam (now often referred to as a TOGAF Standard, Version 9.2 certification exam). The exam doesn't focus on specific minor details but rather on understanding and applying the framework's core concepts. The main points covered extensively can be grouped as follows:

I. TOGAF ADM (Architecture Development Method): This is the heart of the exam. You need a thorough understanding of each phase and its deliverables, including:

• Phase A: Preliminary Phase: Understanding the preliminary phase's goals, including initiating the architecture work, defining the scope, and establishing governance.
• Phase B: Architecture Vision: Defining the architecture vision, business architecture, and the architecture's overall goals.
• Phase C: Business Architecture: Deep understanding of business processes, data models, and information flows within the organization and how they relate to the architecture.
• Phase D: Information Systems Architectures: Defining the application, data, and technology architectures that support the business architecture. This includes understanding different architecture styles and patterns.
• Phase E: Technology Architecture: Focuses on the technical infrastructure, including hardware, software, and networks, that underpin the information systems.
• Phase F: Opportunities and Solutions: Identifying potential solutions, evaluating them against the architecture vision, and selecting the optimal approach.
• Phase G: Migration Planning: Developing a plan for migrating to the target architecture, considering risks and change management.
• Phase H: Implementation Governance: Defining and managing governance processes throughout the implementation.
• Phase I: Architecture Change Management: Managing changes to the architecture after implementation.

II. Architecture Content Framework (ACF): Understanding how the ACF organizes the architecture content and the different architecture building blocks (e.g., applications, data, technology).

III. TOGAF Content Metamodel: Although not explicitly tested in great detail for OGA-031, a fundamental understanding of how concepts are related and structured within the TOGAF framework ensures a sound understanding of other points.

IV. TOGAF Standards: General understanding of the TOGAF standard itself, its purpose, and its relationship to other architecture frameworks and standards.

V. Key Concepts and Principles:

• Architecture Principles: Understanding and applying the core principles guiding architecture decisions.
• Stakeholder Management: Identifying and managing the expectations of various stakeholders.
• Risk Management: Assessing and mitigating risks associated with the architecture.
• Governance: The structure and processes for managing and governing the architecture.
• Architecture Repository: Understanding the purpose and content of an architecture repository.

VI. Case Studies and Scenarios: The exam heavily utilizes scenarios to test your ability to apply the TOGAF ADM and its concepts in practical situations. You should be able to analyze scenarios, identify relevant phases of the ADM, and suggest appropriate solutions.

In short, the OGA-031 exam tests your comprehensive understanding of the TOGAF Standard, Version 9.2, and its application to real-world architecture development. Focusing on the ADM phases, the ACF, key concepts, and practical application is crucial for success. Remember that memorization alone isn't sufficient; you need to understand the why behind the framework's processes and guidelines.
