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

Risk is defined as the effect of uncertainty on objectives, according to the ISO 31000 standard, which provides principles and guidelines for risk management1 Risk can be positive or negative, depending on whether the uncertainty affects the achievement or the failure of the objectives. Risk can also be expressed in terms of likelihood and impact, which indicate the probability and the consequence of the risk occurrence. Risk management is the coordinated activities to direct and control an organization with regard to risk. Risk management is an integral part of the TOGAF standard, as it helps to identify, assess, and treat the risks that may affect the architecture development and implementation2 References: 1: ISO 31000:2018, Risk management — Guidelines, Clause 3.1 2: The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 32: Risk Management

The image shows a diagram that illustrates the basic concepts of architecture description as defined by the ISO/IEC/IEEE 42010:2011 standard1, which is also adopted by the TOGAF standard2.

According to the ISO/IEC/IEEE 42010:2011 standard, an architecture description is a work product used to express an architecture, and it consists of one or more architecture views1.

An architecture view is a representation of a system from the perspective of a related set of concerns, and it conforms to an architecture viewpoint1.

An architecture viewpoint is a specification of the conventions for constructing and using an architecture view to address specific stakeholder concerns1.

Therefore, the correct answer is option A, which identifies the items labeled as “A” and “B” in the image as an architecture viewpoint and an architecture view, respectively. References:

2: TOGAF Standard, Version 9.2 - Part IV: Architecture Content Framework - 31. Architectural Artifacts2

Architecture Principles are general rules and guidelines that inform and support the way in which an organization sets about fulfilling its mission. They reflect a level of consensus among the various elements of the enterprise, and form the basis for making future IT decisions. One of the purposes of Architecture Principles is to establish a common understanding of how to control the business in pursuit of strategic objectives, by providing a framework for evaluating and agreeing on the changes that affect the enterprise’s architecture3 References: 3: The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 23: Architecture Principles : The TOGAF Standard, Version 9.2, Part IV: Architecture Content Framework, Chapter 31: Architecture Principles

 In the ADM documents which are under development and have not undergone any formal review and approval process are called “draft”. This indicates that they are subject to change and refinement as the architecture development progresses. Reference: The TOGAF® Standard | The Open Group Website, Section 4.2.5 Architecture Deliverables.

The purpose of the Gap Analysis technique is similar to the previous question, but with a focus on the Target Architecture. The technique helps to identify the items that are not included or specified in the Target Architecture, such as capabilities, services, components, standards, or technologies. These items may be essential for achieving the vision and goals of the enterprise, or for addressing the stakeholder concerns and requirements. By identifying the items omitted from the Target Architecture, the technique helps to ensure that the architecture is comprehensive, feasible, and realistic.

According to the TOGAF standard, the deliverables that match the descriptions are as follows:

1 Architecture Principles: These are general rules and guidelines, intended to be enduring and seldom amended, that inform and support the way in which an organization sets about fulfilling its mission1. They reflect a level of consensus among the various elements of the enterprise, and form the basis for making future IT decisions1.

2 Architecture Contracts: These are the joint agreements between development partners and sponsors on the deliverables, quality, and fitness-for-purpose of an architecture2. They are used to ensure that the architecture is implemented and governed according to the agreed-upon specifications and standards2.

3 Request for Architecture Work: This is a document that is sent from the sponsoring organization to the architecture organization to trigger the start of an architecture development cycle3. It defines the scope, schedule, budget, deliverables, and stakeholders of the architecture project3.

4 Architecture Requirements Specification: This is a set of quantitative statements that outline what an implementation project must do in order to comply with the architecture4. It defines the requirements for each architecture domain, as well as the relationships and dependencies among them4.

The TOGAF Content Framework defines a detailed model of architectural work products (artifacts, deliverables, building blocks) and the relationships between them.

It is not a lifecycle management capability (A), that is related to the ADM itself.

It is not organized strictly by ADM phases (B).

It is not fixed; it is designed to be tailored (C).

The statement "Projects may cycle between ADM phases, in planned cycles covering multiple phases" illustrates the concept of iteration, which is the process of repeating the ADM phases or steps within a phase to refine the architecture outputs and address the changing requirements and stakeholder concerns. Iteration can occur at different levels of granularity and scope, such as within a single phase, across multiple phases, or across the entire ADM cycle. Iteration can also be applied to different architecture domains, such as business, data, application, and technology. Iteration is a key feature of the ADM that enables the development of architectures that are fit for purpose, adaptable, and responsive to change. References: : The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 24: Applying Iteration to the ADM

According to the TOGAF Standard, 10th Edition, a transformation readiness assessment is a technique that evaluates the preparedness of the organization to undergo a change, and identifies the actions needed to increase the likelihood of a successful outcome. A transformation readiness assessment can be conducted in Phase E: Opportunities and Solutions, and the actions resulting from it can be dealt with in Phase F: Migration Planning 1. In Phase E, the transformation readiness assessment can help to identify the major implementation challenges and risks, and to define the critical success factors and key performance indicators for the architecture project. In Phase F, the actions resulting from the transformation readiness assessment can help to develop a detailed and realistic migration plan, and to address the gaps, issues, and dependencies that may affect the transition to the target architecture 1. References: 1: TOGAF Standard, 10th Edition, Part III: ADM Guidelines and Techniques, Chapter 29: Business Transformation Readiness Assessment.

The Architecture Requirements Specification is one of the TOGAF deliverables that provides a set of quantitative statements that outline what an implementation project must do in order to comply with the architecture12. It is a companion to the Architecture Definition Document, which provides a qualitative view of the solution and aims to communicate the intent of the architect. The Architecture Requirements Specification provides a quantitative view of the solution, stating measurable criteria that must be met during the implementation of the architecture3. It typically forms a major component of an implementation contract or contract for more detailed Architecture Definition4. References:
