The Open Group OGEA-101 - TOGAF Enterprise Architecture Part 1 Exam (English)

An EA Capability is the ability of an organization to perform enterprise architecture effectively and efficiently. It involves establishing and maintaining the appropriate organization structures, roles, responsibilities, skills, processes, tools, and governance mechanisms to support the development and use of enterprise architecture. An EA Capability enables the organization to align its business and IT strategies, deliver value from its investments, manage change and complexity, and improve its performance and agility12 References: 1: The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 44: Introduction 2: The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 45: Establishing and Maintaining an Enterprise Architecture Capability

The statement illustrates iteration and the ADM. Iteration is the technique of repeating a process or a phase with the aim of improving or refining the outcome. Iteration allows for feedback loops and adaptations at any point in the architecture development and transition process. Separate projects may operate their own ADM cycles concurrently, with relationships between the different projects, to address different aspects or levels of the architecture in an iterative manner. Reference: The TOGAF® Standard | The Open Group Website, Section 3.1 Introduction to the ADM.

When scoping an architecture in TOGAF, three key axes (dimensions) are used to frame the extent of the architecture work. The first is time period (how far into the future or over what timeframe to plan). The second is depth—how detailed or granular the architecture models will be (e.g., high level, mid level, very detailed). The third is breadth, which refers to which parts (domains, business units, functions) of the enterprise will be included, and which architecture domains (business, data, application, technology) will be in scope. This triple‐dimension model helps architects, stakeholders, and governance bodies understand how wide, deep, and forwardlooking the architecture effort will be. Thus “breadth, architecture domains” is the correct third dimension.

 According to the TOGAF template for Architecture Principles, the Rationale section should describe the relationship to other principles, as well as the business benefits and the intentions of adhering to the principle. The Rationale section should use business terminology and point to the similarity of information and technology principles to the principles governing business operations. The Rationale section should also explain how the principle supports the achievement of the business objectives and key architecture drivers. References:

According to the TOGAF standard, the need for the ADM process to be governed is to ensure that the architecture development and implementation activities are conducted in a consistent, coherent, and compliant manner1. Governance provides the means to verify that the method is being applied correctly and effectively, and that the architecture deliverables and artifacts meet the quality and standards criteria1. Governance also enables the management of risks, issues, changes, and dependencies that may arise during the ADM process1.

Some of the benefits of governing the ADM process are2:

•Improved alignment of the architecture with the business strategy and objectives

•Enhanced stakeholder engagement and communication

•Increased reuse and integration of architecture assets and resources

•Reduced complexity and duplication of architecture efforts

•Increased agility and adaptability of the architecture to changing needs and requirements

•Improved compliance and auditability of the architecture outcomes and outputs

1E: To identify delivery vehicles (projects programs portfolios) that will deliver the Target Architecture 2F: To confirm readiness and ability to undergo change 3E: To determine whether an incremental approach is required and if so identify Transition Architectures that will deliver continuous business value 4G: To perform appropriate governance functions while the solution is being implemented

The objective of the ADM Implementation Governance Phase is to provide an architectural oversight of the implementation and to ensure conformance for the target architecture. This phase involves establishing procedures and processes to monitor and control the implementation projects and to verify that they comply with the defined architecture. Reference: The TOGAF® Standard | The Open Group Website, Section 3.2.7 Phase G: Implementation Governance.

Based on the illustration, the phase of the ADM labeled as item 2 is the Implementation Governance phase. This phase provides architectural oversight for the implementation. It ensures that the implementation project conforms to the architecture. It also provides a framework for monitoring and managing the implementation.

The Implementation Governance phase involves the following activities:

Finalizing the Architecture Roadmap and the supporting Implementation and Migration Plan

Assigning an Architecture Board to oversee the implementation

Establishing Architecture Contracts with the implementation partners

Reviewing and approving the implementation project plans and deliverables

Performing Architecture Compliance reviews to ensure alignment with the architecture

Performing Architecture Audit reviews to ensure quality and performance of the architecture

Resolving any architecture issues or change requests that arise during the implementation

Maintaining the architecture lifecycle and ensuring its continuity

The Implementation Governance phase is essential for ensuring that the architecture is realized as intended and that it delivers the expected business value and outcomes.
