Scenario: Zephyr Enterprises
Please read this scenario prior to answering the question
Zephyr Enterprises specializes in the development of wind turbine blades for use in large-scale commercial wind energy production systems. Zephyr has manufacturing facilities located in Palm Springs, California, Omaha, Nebraska, and Winnipeg, Ontario. Each of these plants supplies a different manufacturer that builds and sells complete systems. The turbine blades are custom engineered to meet each manufacturers design specifications.
Until recently, most turbine blades were fabricated manually using molded fiber-reinforced plastics. However, recent improvements in composite materials, coupled with enhanced automated methods for precision application of materials during the molding process, have led to significant reduction in weight, increase in strength, and greatly improved blade longevity. Zephyr has pioneered the development of a proprietary automated process for continuous extrusion of the turbine blades. Patents have been filed to protect the process, but certain trade secrets must be closely guarded.
Zephyr has a mature Enterprise Architecture organization that is supported by a cross-functional Architecture Review Board. The Chief Information Officer and the Chief Operating Officer co-sponsor the Enterprise Architecture program.
Zephyr has used TOGAF and its Architecture Development Method (ADM) to develop its automated manufacturing processes and systems that are used to design, manufacture, and test the blade assemblies. They have recently updated to TOGAF 9 and have adapted the Zephyr Enterprise Architecture to closely follow the TOGAF 9 framework. All of Zephyrs IT architects have been trained and certified on TOGAF 9.Recently, an architecture project was completed that defined a standard approach for controlling the Automated Test System that is used at each plant to perform final quality assurance tests on each completed blade assembly.
The Manufacturing Architecture Board approved the plan for immediate implementation at each plant.
An Architecture Contract was developed that detailed the work needed to implement and deploy the new Automated Test System controller. The Chief Engineer, sponsor of the activity, has expressed concern that a uniform process be employed at each site to ensure consistency.
Refer to the Zephyr Enterprises Scenario
You have been assigned by the Lead Architect for the Automated Test System controller project to conduct Compliance Assessments at each manufacturing plant.
During the course of the assessment at the Omaha plant, you discover that the Distributed Data Acquisition System they have purchased uses a proprietary Remote Procedure Call (RPC) that utilizes kernel mode threads instead of the user mode threads that are specified in the Architecture Definition Document. In all other respects, the system meets the requirements stated in the Architecture Definition Document and seems to perform correctly.
You have been asked to describe the compliance of this system for the final report.
Based on TOGAF 9, which of the following is the best answer?
A. You observe that the system has many features in common with the Architecture Definition Document, and those features have been implemented in accordance with the specification. However, you note that the RPC mechanism has been implemented using features that are not covered by the specification.
Your recommendation is that the system be described as consistent.
B. You observe that all of the features in the Architecture Definition Document have been implemented in accordance with the specification, except for the RPC mechanism. Your recommendation is that the system be described as conformant.
C. You observe that the system meets most of the requirements stated in the Architecture Definition Document and appears to work correctly. However, you note that the RPC mechanism has not been implemented according to the specification. Your recommendation is that the system be described as non-conformant.
D. You observe that the implementation of the RPC mechanism has no features in common with the Architecture Definition Document, therefore the question of its conformance should not be considered.
Your recommendation is that the system be described as consistent.
正解：C

Scenario
Please read this scenario prior to answering the question
Your role is that of Lead Enterprise Architect within the headquarters of a large fast food chain. The chain manages over 6000 restaurants across 24 countries. Each restaurant in the chain is an independently owned and operated franchise. Many of the restaurants use have been with the franchise since its initial startup phase and still use the first generation IT systems deployed over 15 years ago.
The CEO of the chain has stated his concerns about the inefficiencies of the current systems and identified the need to change. He has defined a new strategic vision that will enhance the business by providing its franchisees new support services to help them complete with the increasing competition from coffee shops.
This strategy is part of the long-term commitment to enhance the brand image and increase revenue for the chain. He has also stated that he expects improved financial results by the end of the current fiscal year.
These changes will provide the chain with improved products, including healthier alternatives in their menu, and more efficient operations. The addition of a corporate-wide data warehouse will provide analytics that will enable the marketing group to improve its ability to target advertising and new products to specific regions.
The chain has a mature enterprise architecture practice based in its headquarters and uses TOGAF 9 as the method and guiding framework. The CIO is the sponsor of the activity.
In planning this change, the Chief Architect engaged the services of a well-known consulting firm that specializes in business strategy. An initial study has been conducted to identify the strategic changes needed to implement the CEO's vision. This recently completed with approval of a strategic architecture encompassing the entire chain, including detailed requirements and recommendations.
Based on the recommendations from the initial study, the chain has taken the decision to adopt a packaged suite of integrated applications that is tailored to the needs of the franchise.
Refer to the scenario
You have been asked by the Chief Architect to propose the best approach for architecture development to realize the CEO's vision.
Based on TOGAF, which of the following is the best answer?
A. You propose that the team focus on architecture definition, with a specific emphasis on understanding the strategic change parameters of the business strategy. Once understood, the team will be in the best position to identify the requirements, drivers, issues, and constraints for this engagement. You would ensure that the target architecture addresses non-functional requirements so as to ensure the target architecture is robust and secure.
B. You propose that this engagement define the baseline architecture first in order to assess the current infrastructure capacity and capability. The initial priority is to understand the problem. Then the focus should be on transition planning and architecture deployment. This will identify requirements to ensure that the projects are sequenced in an optimal fashion so as to realize the vision.
C. You propose that the team focus on defining the target architecture by going through the architecture definition phases (B-D). This is because the initial study 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 vision.
D. You propose that the target architecture is defined first, followed by transition planning. This is because the vision is well understood and the strategic architecture agreed. The target first approach will ensure that the current problems and inefficiencies of the baseline architecture are not carried forward, and that the proposed solution addresses the requirements identified in the initial study.

The corporation includes 30 subsidiary companies with operations in over 60 countries and products sold in over 125 countries. It has major research and development sites in over 45 locations worldwide.
The management team is deeply committed to ensuring that the corporation is a world leader in socially responsible pharmaceutical development with a business strategy that focuses on profitability through environmentally friendly operating processes as well as a commitment to disease eradication.
The operations of the corporation are subject to legal and regulatory requirements for each country where they operate. The production of prescription pharmaceutical products has governmental controls that are strictly enforced and compliance is critical. Recently a competitor was heavily fined for violating the regulations in a country where it was conducting a clinical trial for a new regulated drug.
The Governing Board is concerned about the risks posed in this complex global environment. As a result the Chief Executive Officer (CEO) has appointed a Chief Compliance Officer (CCO) to be responsible for overseeing and managing compliance issues for the corporation. The CCO reports directly to the CEO.
The CCO has approved the expenditure of resources to establish an Enterprise Architecture program. He has requested to be informed about the status of projects that could impact regulatory compliance. He also wants the corporate legal staff and auditors to analyze all proposed architectures to ensure that they are within the legal guidelines for each country. In addition, the research organization should be able to see that the architecture is appropriate for its needs.
TOGAF 9 has been mandated as the framework for the development and evolution of the Enterprise Architecture practice. The Preliminary Phase has been completed to establish the enterprise architecture capability for this project.
Refer to the Scenario

Scenario: Global Mobile 1
Please read this scenario prior to answering the question
Global Mobile is a mobile telecommunications company formed through a series of mergers and acquisitions.
They are yet to fully integrate the customer service systems for the most recent acquisitions, and as result, customer service has been a major concern for the Chief Technology Officer.
Results for the last two quarters have shown that Average Revenue Per User (ARPU) and the customer retention (Churn) rate have fallen below the industry average. The Corporate Marketing group has published some new findings about customer satisfaction. The customers appear to be switching to Air Light, a competitor, because of superior customer service. Global Mobile actually has better coverage in nearly all markets than Air Light, and good roaming agreements that keep rates low for business travelers. But, customer satisfaction has remained low.
The Business Strategy group and the Enterprise Architecture group have conducted a high-level project to develop the enterprise-wide strategic plan. They have developed a business scenario which contains a good conceptual model of what needs to be done, and also identifies the key requirements. This was used in preparing the proposal presented to the Executive Council and the Corporate Board.
The planning for the program has been underway for several months. Global Mobile has selected TOGAF 9 as the basis for its Enterprise Architecture.
The Corporate Board has approved funding for a multi-million Euro conversion to transition to a packaged Customer Service System. It is anticipated that the overall program will take five years to complete, but there are some tactical projects that can commence immediately to address the situation. The Corporate Board has placed one additional major constraint on the program. In addition to achieving the business outcomes directly related to improving overall customer service within each business unit, the Corporate Board expects the Target Architecture to produce an additional saving of at least 30% over current operating costs through energy efficiency initiatives, virtualization of servers and workstations, and expanded telecommuting and desk-sharing. This Green initiative is intended to become a model for future investments at all company facilities worldwide.
Refer to Global Mobile scenario
You have been engaged as a consultant to advise the Chief Architect on the best ways to approach to the implementation planning activities for this significant business transformation.
Based on TOGAF 9, which of the following is the best answer? (Is this the right answers to choose?)
A. You recommend using conventional implementation planning techniques. The Capability-Based Planning approach is normally only used in public sector, defense-related programs. This approach is not appropriate for a private sector company.
B. You recommend using conventional implementation planning techniques. The horizontal scope of the Green initiative would make the Capability-Based Planning approach used in the organization's TOGAF-based Enterprise Architecture framework difficult to manage and govern. This approach to planning was better applied within the vertical scope of a business unit.
C. The Capability-Based Planning approach used in the organization's TOGAF-based Enterprise Architecture framework is focused on business outcomes. The Green initiative is an infrastructure program that is technical in nature; therefore, it would not be appropriate to use the Capability-Based Planning approach. Instead, the Global Mobile systems development lifecycle approach should be utilized to develop the Solution Architecture.
D. You recommend that the implementation planning activities be conducted using Capability-Based Planning. This is appropriate because the Green initiative is an enterprise-wide plan with a horizontal scope. Its metrics are aggregated at the enterprise level. It is crucial to gain business unit support and cooperation to achieve the broader business outcomes which will benefit all.

Scenario: AutoComp Corporation
AutoComp Corporation produces components for the Car industry. Driven by the global financial downturn they are looking to reduce IT costs. They believe there is a cost saving opportunity within IT but this is not quantified in terms of potential savings nor is there agreed target architecture.
Final decisions on the solutions are not yet fully agreed. They have completed their Vision Phase and first pass of the three architecture definition phases and now they want to finalize and plan their solutions. You are the Chief Architect from a consulting organization brought into review the work to date by AutoComp Corporation and to make recommendations to the CIO and the board on this.
Which of the following answers best describes how TOGAF recommends in this context?
A. I would after confirming Enterprise Change Attributes and constraints, do a Consolidated Gap Analysis then dependencies, then group and allocate the transitions. I would also assess Enterprise readiness and risks.Then I would also assess the business value of the solutions, do risk analysis with mitigation and then schedule the work products.
B. I would do a Consolidated Gap Analysis by considering then dependencies, then group and allocate the transitions. I would then look to produce artifacts that describe the recommended projects, the risk, issues and dependencies. This would also include transition architects to move us from current architecture to the recommended target architectures. I would present my recommendations to the board for agreement. Once this is done, I would update the architectures reflecting any changes resulting from the board discussion.
C. I would determine the business value of each solution, prioritize accordingly each set of solutions, conduct detailed Risk Assessment and Mitigation, do Compliance reviews and then implement the solutions. I would present my recommendations to the board for agreement. Once this is done, I would update the architectures reflecting any changes resulting from the board discussion.
D. I would look at the corporate culture and attitude to change, understand the constraints such as cost and the required time horizons. I would then look at the architecture work to ensure it is complete and seek to address any gaps. I would review the functional requirements and ensure there are complete interoperability requirements. I would then validate any dependencies and risks. Then formulate an implementation and migration strategy identifies major work packages and the transition architecture required. Finally, once agreement is reached with the board I will create project charters and re-factor any changes needed from the board discussion into the architecture.
