Topic 2: Part 2
Please read this scenario prior to answering the question.
You are the Lead Enterprise Architect at a major agribusiness company. The company's main harvest is lentils, a highly valued food grown worldwide. The lentil parasite, broomrape, has been an increasing concern for many years and is now becoming resistant to chemical controls. In addition, changes in climate favor the propagation and growth of the parasite. As a result, the parasite cannot realistically be exterminated, and it has become pandemic, with lentil yields falling globally.
In response to the situation, the CEO has decided that the lentil fields will be used for another harvest. The company will also cease to process third-party lentils and will repurpose its processing plants. Thus, the target market will change, and the end-products will be different and more varied.
The company has recently established an Enterprise Architecture practice based on the TOGAF standard as method and guiding framework. The CIO is the sponsor of the activity. A formal request for architecture change has been approved. At this stage there is no fixed scope, shared vision, or objectives.
Refer to the scenario:
You have been asked to propose the best approach for architecture development to realize the CEO's change in direction for the company.
Based on the TOGAF standard which of the following is the best answer?
A. You propose that this engagement define the baseline Technology Architecture first in order to assess the current infrastructure capacity and capability for the company. Then the focus should be on transition planning and incremental architecture deployment. This will identify requirements to ensure that the projects are sequenced in an optimal fashion so as to realize the change.
B. You propose that the team uses the architecture definition document and focus on architecture development starting simultaneously phases B, C and D. This is because the CEO has identified the need to change. This will ensure that the change can be defined in a structured manner and address the requirements needed to realize the change.
C. You propose that the team focus on architecture definition including development of business models, with emphasis on defining the change parameters to support this new business strategy that the CEO has identified. Once understood, the team will be in the best position to identify the requirements, drivers, issues, and constraints for the change.
D. You propose that the priority is to produce a new Request for Architecture Work leading to development of a new Architecture Vision. The trade-off method should be applied to identify and select an architecture satisfying the stakeholders. For an efficient change the EA team should be aligned with the organization's planning, budgeting, operational, and change processes.
Explanation:
A Request for Architecture Work is a document that describes the scope, approach, and expected outcomes of an architecture project. A Request for Architecture Work is usually initiated by the sponsor or client of the architecture work, and approved by the Architecture Board, which is a governance body that oversees the architecture work and ensures compliance with the architecture principles, standards, and goals. A Request for Architecture Work triggers a new cycle of the Architecture Development Method (ADM), which is the core process of the TOGAF standard that guides the development and management of the enterprise architecture.
An Architecture Vision is a high-level description of the desired outcomes and benefits of the proposed architecture. An Architecture Vision is the output of Phase A: Architecture Vision of the ADM cycle, which is the first phase of the architecture development. An Architecture Vision defines the scope and approach of the architecture work, and establishes the business goals and drivers that motivate the architecture work. An Architecture Vision also involves obtaining the approval and commitment of the sponsors and other key stakeholders, and initiating the Architecture Governance process.
A trade-off analysis is a technique that can be used to evaluate and compare different architecture alternatives and select the most suitable one. A trade-off analysis involves identifying the criteria and factors that are relevant to the decision, such as costs, benefits, risks, and opportunities, and assessing the strengths and weaknesses of each alternative. A trade-off analysis also involves balancing and reconciling the multiple, often conflicting, requirements and concerns of the stakeholders, and ensuring alignment with the Architecture Vision and the Architecture Principles.
Therefore, the best answer is D, because it proposes the best approach for architecture development to realize the CEO’s change in direction for the company. The answer covers the Request for Architecture Work, the Architecture Vision, and the trade-off analysis techniques that are relevant to the scenario.
Please read this scenario prior to answering the question
You are working as the Chief Enterprise Architect within a law firm specializing in personal injury cases. Many of the firm's competitors have improved their litigation strategies, and efficiency by streamlining their processes using Artificial Intelligence {Al).
The CIO has approved a Request for Architecture Work to examine the use of Machine Learning in defining a new Al-driven litigation and finance process for the firm. This process would instruct the lawyers and analysts as to what tasks and portfolio they should work on. The key objectives are to increase task profitability, maximize staff utilization, and increase individual profitability.
The CIO has emphasized that the architecture should enable the fast implementation of continuous Machine Learning. The solution will need to be constantly measured for delivered value and be quickly iterated to success.
Some of the partners have expressed concerns about letting the Al make the decisions, others about the risks associated with use of it for the type of service they deliver. The CIO wants to know if these concerns can be addressed, and how risks will be covered by a new architecture enabling Al and Machine Learning.
Refer to the scenario
You have been asked to respond to the CIO recommending an approach that would enable the development of an architecture that addresses the concerns of the CIO and the concerns of the partners.
Based on the TOGAF standard which of the following is the best answer?
A. You recommend that a Communications Plan be created to address the key stakeholders, the most powerful and influential partners. This plan should include a report that summarizes the key features of the architecture reflecting their requirements. You will check with each key stakeholder that their concerns are being addressed. Risk mitigation and agility will be explicitly addressed as a component of the architecture being developed.
B. You recommend that an analysis of the stakeholders is undertaken resulting in documenting the stakeholders and their concerns in a Stakeholder Map. The concerns and relevant views should then be defined for each group and recorded in the Architecture Vision document. The requirements will include risk mitigation through regular assessments. This will also allow a supervised agile implementation of the continuous Machine Learning.
C. You recommend that all possible models be created for each candidate architecture that will enable the Al and Machine Learning solution. This ensures that all the necessary data and detail is addressed. A formal review should be held with the stakeholders to verify that their concerns have been properly addressed by the models. Agility will be considered during Phase G Implementation Governance.
D. You recommend creation of a set of business models that can be applied uniformly across all architecture projects. The stakeholders will be trained to understand the business models to ensure they can see that their concerns are being addressed. Risk will be addressed once the Security Architecture is developed, which will happen later to avoid slowing down the agility required by the CIO.
Explanation:
A Stakeholder Map is a technique that can be used to identify and classify the stakeholders of the architecture work, and to document their key interests, requirements, and concerns. A stakeholder is any person, group, or organization that has a stake in the outcome of the architecture work, such as the sponsor, the client, the users, the suppliers, the regulators, or the competitors. A Stakeholder Map can help to understand the needs and expectations of the stakeholders, and to communicate and engage with them effectively.
The steps for creating a Stakeholder Map are:
Which of the following best describes the purpose of the Gap Analysis technique?
A. To govern the architecture throughout its implementation process
B. To develop a set of general rules and guidelines for the architecture
C. To identify items omitted from the Target Architecture
D. To allocate resources for architecture projects
Explanation: 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.
Which of the following best describes the purpose of the Architecture Requirements Specification?
A. It contains an assessment of the current architecture requirements
B. It provides a set of statements that outline what a project must do to comply with the architecture
C. It is sent from the sponsor and triggers the start of an architecture development cycle
D. It defines the scope and approach to complete an architecture project
Explanation: 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 architecture. 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 architecture. It typically forms a major component of an implementation contract or contract for more detailed Architecture Definition.
What is an objective of the ADM Implementation Governance Phase?
A. To provide continual monitoring of the governance framework
B. To ensure conformance for the target architecture
C. To finalize the Implementation and Migration Plan
D. To establish the resources for architecture governance
Explanation: 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.
Which of the following best describes a purpose of the Gap Analysis technique?
A. To validate non-functional requirements
B. To establish quality metrics for the architecture
C. To determine service levels for the architecture
D. To identify missing functions
Explanation: Gap analysis is a technique that is used to validate an architecture by highlighting the shortfall between the Baseline Architecture and the Target Architecture. One of the purposes of gap analysis is to identify missing functions that are either deliberately omitted, accidentally left out, or not yet defined in the Target Architecture. Missing functions are marked as gaps that need to be filled by developing or procuring the building blocks.
Which of the following describes the practice by which the enterprise architecture is managed and controlled at an enterprise-wide level?
A. Corporate governance
B. Architecture governance
C. IT governance
D. Technology governance
Explanation: 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.
Complete the following sentence:
Presenting different_________and_________to stakeholders helps architects to extract hidden agendas principles and requirements that could impact the final Target Architecture
Explanation: According to the TOGAF Standard, an architecture view is a representation of a system from the perspective of a related set of concerns1. An architecture viewpoint is a specification of the conventions for a particular kind of architecture view1. Presenting different architecture views and architecture viewpoints to stakeholders helps architects to extract hidden agendas, principles, and requirements that could impact the final target architecture. This is because different stakeholders may have different concerns and interests in the system, and by showing them how the system addresses their concerns from different perspectives, the architects can elicit more feedback and validation from them2. For example, a business stakeholder may be interested in the business architecture view, which focuses on the business processes, functions, and capabilities of the system3. A security stakeholder may be interested in the enterprise security view, which addresses the security aspects of the system, such as confidentiality, integrity, and availability3. By presenting these views to the respective stakeholders, the architects can ensure that the system meets their expectations and needs, and also identify any potential issues or gaps that may affect the target architecture.
Which ADM phase focuses on defining the problem to be solved, identifying the stakeholders, their concerns, and requirements?
A. Phase
B. Preliminary Phase
C. Phase
D. Phase A
Explanation: Phase A: Architecture Vision is the first phase of the Architecture Development Method (ADM) cycle, which is the core of the TOGAF standard. The main purpose of this phase is to define the scope and approach of the architecture development, and to create the Architecture Vision, which is a high-level description of the desired outcomes and benefits of the proposed architecture. To achieve this purpose, this phase focuses on defining the problem to be solved, identifying the stakeholders, their concerns, and requirements, and establishing the business goals and drivers that motivate the architecture work. This phase also involves obtaining the approval and commitment of the sponsors and other key stakeholders, and initiating the Architecture Governance process.
Which of the following best describes purpose of the Business Scenarios?
A. To identify risk when implementing an architecture project
B. To identify and understand requirements
C. To catch errors in a project architecture early
D. To guide decision making throughout the enterprise
Explanation: Business scenarios are a technique for capturing, clarifying, and communicating the functional and non-functional requirements of a system. Business scenarios describe the business environment, the actors involved, the desired outcomes, and the processes or rules that govern the behavior of the system. Business scenarios are useful for ensuring that the architecture addresses the real needs and concerns of the stakeholders, and for validating and testing the architecture against expected situations. Business scenarios are developed in Phase A: Architecture Vision of the ADM cycle, and refined and updated throughout the other phases.
Complete the sentence The Enterprise Continuum provides methods for classifying architecture artifacts as they evolve from________________________.
Explanation: The Enterprise Continuum provides methods for classifying architecture artifacts as they evolve from generic architectures to Organization-Specific Architectures. Generic architectures are architectures that have been developed for use across a wide range of enterprises with similar characteristics. They provide common models, functions, and services that can be reused and adapted for specific purposes. Organization-Specific Architectures are architectures that have been tailored to meet the needs and requirements of a particular enterprise or a major organizational unit within an enterprise. They reflect the unique vision, goals, culture, structure, processes, systems, and technologies of that enterprise or unit.
Which of the following are interests important to the stakeholders in a system?
A. Requirements
B. Principles
C. Concerns
D. Architecture views
Explanation: Concerns are interests important to the stakeholders in a system. They are used to identify and classify the system’s stakeholders and to guide the selection of viewpoints for the architecture description.
