Enterprises are examples of the scope of an architecture according to the TOGAF Standard. An enterprise is defined as any collection of organizations that has a common set of goals and/or a single bottom line. Enterprises can be whole corporations or divisions of a corporation, government agencies or single government departments, partnerships and alliances of businesses working together, etc. Reference: The TOGAF® Standard | The Open Group Website, Section 2.1 Core Concepts.

According to the TOGAF Standard, 10th Edition, an architecture contract is “a formal agreement between a service provider and a service consumer that defines the mutual commitments and expectations for the delivery of an architecture” 1. An architecture contract is a governed approach of aparticular deliverable that will ensure adherence to the principles, standards, and requirements of the existing or developing architectures, as it specifies the roles, responsibilities, deliverables, quality criteria, and acceptance criteria for the architecture work 1. The other options are not correct, as they are not governed approaches of a particular deliverable, but rather different types of deliverables within the architecture development process. An architecture vision is “a high-level, aspirational view of the target architecture” 1. A statement of architecture work is “a document that defines the scope and approach that will be used to complete an architecture project” 1. An architecture definition document is “a document that describes the baseline and target architectures for one or more domains” 1. References: 1: TOGAF Standard, 10th Edition, Part I: Introduction, Chapter 3: Definitions.

An Enterprise Architecture Capability is the ability of the organization to perform effective and efficient architecture work, including the definition, governance, and management of its architectures2. The Preliminary Phase involves the following activities1:

•Reviewing the organizational context, scope, and drivers for conducting Enterprise Architecture

•Establishing the Architecture Capability desired by the organization, including the maturity level, roles, responsibilities, processes, and tools

•Defining and establishing the Organizational Model for Enterprise Architecture, which describes how the architecture function is organized and integrated within the enterprise

•Defining and establishing the Architecture Governance framework, which provides the mechanisms for ensuring the quality, consistency, and compliance of the architecture work

•Selecting and implementing the tools that support the Architecture Capability, such as repositories, modeling tools, and communication tools

•Defining the Architecture Principles that will guide and constrain the architecture work, based on the business principles, goals, and drivers of the organization

•Defining the Organization-Specific Architecture Framework, which is an adaptation of the generic TOGAF ADM to suit the specific requirements, standards, and practices of the organization

The Preliminary Phase is essential for preparing the organization for the successful development and implementation of its architectures, as well as for ensuring the alignment of the architecture work with the business strategy and objectives1.

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

According to the TOGAF Standard, 10th Edition, the Preliminary Phase of the Architecture Development Method (ADM) has the purpose to develop an Enterprise Architecture Capability 1. An Enterprise Architecture Capability is the ability of the organization to perform the activities and tasks related to Enterprise Architecture, such as defining the scope, principles, vision, governance, and stakeholders of the architecture. The Preliminary Phase also establishes the architecture framework, the architecture repository, the architecture tools, and the architecture team 1. The other options are not correct, as they have different purposes in the ADM. Phase G: Implementation Governance has the purpose to ensure that the implementation projects conform to the target architecture 2. Phase A: Architecture Vision has the purpose to define the scope, stakeholders, business drivers, and objectives of the architecture project 3. Phase B: Business Architecture has the purpose to describe the baseline and target business architecture, and to identify the gaps between them . References: 1: TOGAF Standard, 10th Edition, Part II: Architecture Development Method, Chapter 6: Preliminary Phase. 2: TOGAF Standard, 10th Edition, Part II: Architecture Development Method, Chapter 18: Phase G: Implementation Governance. 3: TOGAF Standard, 10th Edition, Part II: Architecture Development Method, Chapter 12: Phase A: Architecture Vision. : TOGAF Standard, 10th Edition, Part II: Architecture Development Method, Chapter 13: Phase B: Business Architecture.

Gap Analysis is a technique that compares the Baseline Architecture and the Target Architecture to identify the differences and gaps between them. The purpose of this technique is to determine the changes and additions that are required to achieve the desired future state of the architecture. One of the main aspects of Gap Analysis is to identify the functions that aremissing or overlapping in the current and future architectures, and to plan how to address them. This helps to ensure that the architecture is complete, consistent, and aligned with the business objectives and requirements3

The purpose of Enterprise Architecture is to guide effective change by providing a coherent and consistent view of the enterprise’s current and future state, as well as the roadmap and principles for achieving it. Enterprise Architecture helps to align business and IT strategies,optimize resources and investments, reduce complexity and risks, enhance agility and innovation, and deliver value to stakeholders. Reference: The TOGAF® Standard | The Open Group Website, Section 1.3 Executive Overview.

The ability to develop, use, and sustain the architecture of a particular enterprise using architecture to govern change is an EA Capability. An EA Capability is a set of skills, processes, roles, responsibilities, tools, and techniques that enable an enterprise to successfully develop and maintain its Enterprise Architecture and achieve its desired outcomes. An EA Capability is part of an enterprise’s overall capability portfolio and should be aligned with its strategy and objectives. Reference: The TOGAF® Standard | The Open Group Website, Section 3.2 Preliminary Phase.

The Business Transformation Readiness Assessment technique is used to evaluate the readiness of the organization to undergo change and to identify the actions needed to increase the likelihood of a successful business transformation. These actions should be incorporated in the Implementation and Migration Plan, which is the detailed plan to transition from the Baseline Architecture to the Target Architecture. The Implementation and Migration Plan also includes the Transition Architectures, the Architecture Building Blocks, the Work Packages, the Implementation Governance Model, and the Architecture Contract12 References: 1: The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 27: Business Transformation Readiness Assessment 2: The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 21: Phase F: Migration Planning

Risk Management is the process of identifying, assessing, and responding to risks that may affect the achievement of the enterprise’s objectives. Risk Management involves balancing positive and negative outcomes resulting from the realization of either opportunities or threats. Reference: The TOGAF® Standard | The Open Group Website, Section 3.3.3 Risk Management.

The Architecture Landscape is divided into levels known as Segment Strategic and Capability Architectures. These levels correspond to different scopes and purposes of architectures within an enterprise. Segment Architectures are architectures that address specific business units, functions, or processes within an enterprise. Strategic Architectures are architectures that provide a high-level view of the enterprise’s vision, goals, and direction. Capability Architectures are architectures that address specific business capabilities or services that span multiple segments or domains. Reference: The TOGAF® Standard | The Open Group Website, Section 2.4 Architecture Repository.

The class of information known as the Reference Library within the Architecture Repository contains guidelines and templates used to create new architectures. The Reference Library provides a set of resources that can be leveraged or customized for specific architecture development purposes. It includes generic building blocks, patterns, models, standards, frameworks, methods, techniques, best practices, etc. Reference: The TOGAF® Standard | The Open Group Website, Section 2.4 Architecture Repository.

The table describes the output, outcome, and essential knowledge of an ADM phase that oversees the implementation of changes necessary to reach the adjusted target state. This corresponds to Phase G, also known as Implementation Governance, which ensures that the architecture defined in earlier phases is realized, and it oversees the development and implementation of projects to align with this architecture. The essential knowledge required during this phase includes understanding constraints on the implementation team and adjusting stakeholder priority and preference in response to success, value, effort, and risk of change. References: TOGAF Version 9.1 - 1

Business principles business goals, and business drivers provide context for architecture work, by describing the needs and ways of working employed by the enterprise. They define what the enterprise wants to achieve, how it wants to operate, and what factors influence its decisions and actions. Reference: The TOGAF® Standard | The Open Group Website, Section 3.2 Preliminary Phase.

According to the TOGAF Standard, 10th Edition, risk is present in all phases within the Architecture Development Method (ADM), and it should be identified, classified, and mitigated before starting a transformation effort 1. Risk is defined as “the effect of uncertainty on objectives” 2, and it can have positive or negative impacts on the architecture project. Risk management is a technique that helps to assess and address the potential risks that may affect the achievement of the architecture objectives, and to balance the trade-offs between opportunities and threats. Risk management is applied throughout the ADM cycle, from the Preliminary Phase to the Requirements Management Phase, and it is integrated with other techniques, such as stakeholder management, business transformation readiness assessment, gap analysis, and migration planning 1. The other options are not correct, as they are not present in all phases within the ADM, and they are not necessarily identified, classified, and mitigated before starting a transformation effort. Budgetary constraints are the limitations on the financial resources available for the architecture project, and they are usually considered in Phase E: Opportunities and Solutions, and Phase F: Migration Planning 3. Schedule constraints are the limitations on the time available for the architecture project, and they are also usually considered in Phase E and F 3. Information gaps are the missing or incomplete data or knowledge that may affect the architecture project, and they are usually identified in Phase B: Business Architecture, Phase C: Information Systems Architecture, and Phase D: Technology Architecture . References: 1: TOGAF Standard, 10th Edition, Part III: ADM Guidelines and Techniques, Chapter 32: Risk Management. 2: TOGAF Standard, 10th Edition, Part I: Introduction, Chapter 3: Definitions. 3: TOGAF Standard, 10th Edition, Part II: Architecture Development Method, Chapter 16: Phase E: Opportunities and Solutions, and Chapter 17: PhaseF: Migration Planning. : TOGAF Standard, 10th Edition, Part II: Architecture Development Method, Chapter 13: Phase B: Business Architecture, Chapter 14: Phase C: Information Systems Architecture, and Chapter 15: Phase D: Technology Architecture.

In the context of TOGAF, a stakeholder is any individual, team, or organization who has interests in, or concerns relative to, the outcome of the architecture. Concerns are those interests which pertain to any aspect of the system’s functioning, development or operation, including considerations such as performance, reliability, and security1. References:

•The TOGAF Standard, Version 9.2 - Definitions - The Open Group

Phase B of the ADM cycle is the Business Architecture phase. It describes the development of a Business Architecture to support an agreed Architecture Vision. The objectives of this phase are to describe the baseline and target Business Architecture, identify candidate Architecture Roadmap components based on gaps between the baseline and target, and determine whether an incremental approach is required. Reference: The TOGAF® Standard | The Open Group Website, Section 3.2.2 Phase B: Business Architecture.

According to the TOGAF Standard, 10th Edition, architecture governance is “the practice by which enterprise architectures and other architectures are managed and controlled at an enterprise-wide level” 1. Architecture governance ensures that the architecture development and implementation are aligned with the strategic objectives, principles, standards, and requirements of the enterprise, and that they deliver the expected value and outcomes. Architecture governance also involves establishing and maintaining the architecture framework, repository, board, contracts, and compliance reviews 1. The other options are not correct, as they are not the term used by the TOGAF Standard to describe the practice by which the enterprise architecture is managed and controlled at an enterprise-wide level. Corporate governance is “the system by which an organization is directed and controlled” 2, and it covers aspects such as leadership, strategy, performance, accountability, and ethics. IT governance is “the system by which the current and future use of IT is directed and controlled” 2, and it covers aspects such as IT strategy, policies, standards, and services. Technology governance is “the system by which the technology decisions and investments are directed and controlled” 3, and it covers aspects such as technology selection, acquisition, deployment, and maintenance.

The planning horizon, depth, and breadth of an Architecture Project, along with the contents of the EA Repository, are typically framed by Strategy, Portfolio,Segment, and End-to-end Target Architecture. The 'Segment' refers to a part of the organization, typically addressed in a Segment Architecture, while 'End-to-end Target Architecture' encompasses the complete view of the planned architecture across the entire organization.

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

One of the key responsibilities of an Architecture Board within the context of TOGAF is to achieve consistency between sub-architectures. This board is typically responsible for overseeing the development and maintenance of the enterprise architecture, ensuring that it aligns with the organization's overall strategy and objectives. They play a critical role in ensuring that all sub-architectures (like Business Architecture, Data Architecture, Application Architecture, and Technology Architecture) work together cohesively and support the overall enterprise architecture vision and strategy.

 In Phase E of the ADM cycle, building block gaps become associated with work packages that will address the gaps. This phase involves creating an Implementation and Migration Plan that defines a set of work packages and Transition Architectures that will deliver the Target Architecture. Reference: The TOGAF® Standard | The Open Group Website, Section 3.2.5 Phase E: Opportunities & Solutions.

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:
