Scenario: Vittronics Ltd.
Please read this scenario prior to answering the question
Vittronics Ltd. is a leading medical device manufacturer in the highly competitive market for Migraine Headache Pain Management (MHPM) devices. These tiny wireless devices are implanted in the brain and can deliver a precise electric shock when the wearable Pain Control Unit (PCU) detects an increase in stress induced by the onset of a migraine headache.
This technology will be a breakthrough in the treatment of this condition, and several competitors are striving to be the first to introduce a product into the market. However, all of them must demonstrate the effectiveness and safety of their products in a set of clinical trials that will satisfy the regulatory requirements of the countries in the target markets.
The Enterprise Architecture group at Vittronics has been engaged in an architecture development project to create a Secure Private Immersive Collaborative Environment (SPICE) that will allow researchers at its product development laboratories worldwide to share information about their independent clinical trials.
The Vittronics Enterprise Architecture group is a mature organization that has been utilizing TOGAF for several years. They have recently upgraded to TOGAF 9. The Vittronics Architecture Development Method (VADM) is strictly based on the TOGAF 9 Architecture Development Method (ADM) with extensions required to support current good manufacturing practices and good laboratory practices in their target markets.
The SPICE project team has now completed the Business, Information Systems, and Technology Architecture phases and has produced a complete set of deliverables for each phase. Due to the highly sensitive nature of the information that is managed in SPICE, special care was taken to ensure that each architecture domain included an examination of the security and privacy issues that are relevant for each domain. A corresponding SPICE Security Architecture has been defined.
The Executive Vice President for Clinical Research is the sponsor of the Enterprise Architecture activity.
Refer to the Vittronics Ltd Scenario:
You are serving as the Lead Architect for the SPICE project team.
As required by TOGAF, the SPICE project team res completed a Business Transformation Readiness Assessment in Phase A (Architecture Vision). In that assessment, it was determined that there are risks associated with the adoption of the Immersive Collaborative Environment. Despite a clear expression of the vision and the business need for utilizing SPICE to accelerate the clinical trials, the researchers have been resisting the change because of concerns about safeguarding individually identifiable information about the subjects who were participating in the trials.
You have been asked to recommend how this situation be managed in the implementation planning phases.
Based on TOGAF 9, which of the following is the best answer?
A. You decide that in Phase E, the team creates an overall solutions strategy that can guide the Target Architecture implementation and structure the Transition Architectures. You check that there is
consensus before proceeding.
B. You decide to return to Phase A, where the team should brainstorm a technical solution that mitigates the residual risks presented by the privacy issue. Then, during Phase D, you will direct the team to develop an Architecture Building Block to manage the security risks. After that, the team should select Solution Building Blocks that mitigate all of the identified risks and revise the Requirements Impact Statement to reflect the changes to the high-level solutions strategy and migration plan.
C. You decide that in Phase E, the team review the Business Transformation Readiness Assessment and identify, classify, and mitigate the risks associated with the identified readiness factors. If the risks can be satisfactorily mitigated, then you would continue to define a high-level solutions strategy that includes the Transition Architectures needed to make the change culturally and technically feasible.
D. You decide that in Phase E, the team determines an approach to implementing an overall strategic direction that will address and mitigate the risks identified.
Scenario: Please read this scenario prior to answering the question You are the Lead Enterprise Architect in a company that specializes in the development of wind turbine blades for use in large-scale commercial wind energy production systems. The company has manufacturing facilities located in Illinois, Nebraska, and Manitoba. Each of these plants supplies a different manufacturer that builds and sells complete systems. The turbine blades are custom engineered to meet each manufacturer's 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 improved blade longevity. The company 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.
The company has a mature Enterprise Architecture organization that is supported by a cross-functional Architecture Board. The Chief Information Officer and the Chief Operating Officer co-sponsor the Enterprise Architecture program.
TOGAF 9 and its Architecture Development Method (ADM) are used to develop the automated
manufacturing processes and systems that are used to design, manufacture, and test the blade
assemblies.
Recently, a pilot architecture project was completed at a single location 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 Architecture Board approved the plan for immediate
implementation at each plant.
Architecture Contracts have been developed that detail the work needed to implement and deploy the new
Automated Test System controller for each location. The Chief Engineer, sponsor of the activity, has
expressed concern that a uniform process be employed at each location to ensure consistency.
Refer to the Scenario
You have been asked to recommend the best approach to address the Chief Engineer's concern.
Based on TOGAF 9, which of the following is the best answer?
A. You review the applicable Architecture Contract for each location, ensuring that it addresses the project objectives, effectiveness metrics, acceptance criteria, and risk management. In cases where the contract is issued to an external party, you ensure that it is a legally enforceable contract. You schedule compliance reviews at key points in the implementation process to ensure that the work is proceeding in accordance with the Architecture Definition. You ensure that the Architecture Board reviews all deviations from the Architecture Contract, and considers whether or not to grant a dispensation to allow the implementation organization to customize the process to meet their local needs.
B. You create an Architecture Contract to manage and govern the implementation and migration process at each location. For internal development projects, you issue a memorandum of understanding between the Architecture Board and the implementation organization. For contracts issued to an external party, you ensure that it is a fully enforceable legal contract. You ensure that the Architecture Board reviews all deviations from the Architecture Contract, and considers whether or not to grant a dispensation to allow the implementation organization to customize the process to meet their local needs.
C. You create an Architecture Contract to manage and govern the implementation and migration process. If the contract is issued to an external party, you ensure that it is a fully enforceable legal contract. For internal development projects, you decide it is adequate to utilize a memorandum of understanding between the Architecture Board and the implementation organization. You recommend that if a deviation from the Architecture Contract is detected, the Architecture Board grant a dispensation to allow the implementation organization the ability to customize the process to meet their local needs.
D. You use the issued Architecture Contracts to manage the architecture governance processes for the project across the locations. You deploy monitoring tools to assess the performance of the completed blade assembly at each location and develop change requirements if necessary. You recommend that if a deviation from the contract is detected, the Architecture Board should modify the Architecture Contract to allow the implementation organization the ability to customize the process to meet their local needs. As a result, you then issue a new Request for Architecture Work to implement the modified Architecture Definition.
Scenario: Please read this scenario prior to answering the Question You are serving as the Chief Architect for a large, global commodities trading company which has been growing rapidly through a series of acquisitions. Each business is performing well in its markets. However, the lack of integration between headquarters and the business units has increasingly caused problems in the handling of customer and financial information. The inability to share information across businesses has resulted in lost opportunities to "leverage the synergies" that had been intended when the businesses were acquired. At present, each business unit maintains its own applications. Despite an earlier initiative to install a common application to manage customer, products, supplier, and inventory information, each business unit has different ways of defining each of these core elements and has customized the common application to the point where the ability to exchange information is difficult, costly, and error-prone. As a result, the company has made the decision to introduce a single enterprise-wide application to consolidate information from several applications that exist across the lines of business. The application will be used by all business units and accessed by suppliers through well defined interfaces.
Refer to the Scenario As part of the process for establishing the Enterprise Architecture department, you are developing a set of architecture principles to guide the activities. You need to specify the best approach for this work. Based on TOGAF 9, which of the following is the best answer?
A. You gather information from credible industry sources in the commodities business. Based on that, you assess current trends and apply that to defining a set of principles that embody best practices. You select architecture principles that do not conflict with each other and that should be stable. You ensure that all the principles are realistic and avoid including principles that are obvious.
B. You examine the mission statements for the company and each of its businesses, together with the corporate value statements. Based on that, you define a set of principles and review with the CIO. When developing the principles you ensure that they actively promote the alignment of IT with the business strategies and initiatives of the company. You then seek the endorsement of the CIO and senior management.
C. You define a set of principles that support the preferred best practices embodied in the Enterprise Architecture department charter. You publish the principles on the corporate intranet to ensure widespread acceptance and compliance.
You then schedule regular periodic Compliance Assessments with individual business units to check
that they have made satisfactory progress toward meeting the objectives and conditions embodied in
the principles.
D. You examine the mission statements for the company and each of its businesses, together with the corporate value statements. Based on that, you work with the Architecture Board to define the principles. When developing the principles you ensure that they actively promote the alignment of IT with the corporate business strategies. You then hold a series of review meetings with all the relevant stakeholders, including senior management, ensuring their support.
TP Banking is a strong financial institute with a well-known acquisition history with an internal IT department managing over 100 projects related to infrastructure and services. The CIO has decided to create an Enterprise Architecture based on TOGAF 9 as reaction to the difficult market conditions. An Architecture Vision and a set of domain architectures were approved. The CIO is asking you (the Lead Architect) to define an Implementation and Migration Plan that realizes the vision already agreed with the stakeholders involved.
Refer to the scenario above You are leading a group of domain architects and you are working with the corporate PMO, the business strategy team and service operations. You are meeting the stakeholders to clarify how you want to proceed with the Implementation and Migration Plan.
Choose one of the following answers
A. You propose to start collecting the existing deliverables describing the different domains in order to enable the Enterprise Architecture tram to integrate them with the support of the operation management. Every domain architect will then evaluate the impact on the projects already planned for the domain. The single revised plans will be integrated together and consolidated into a strategic implementation and migration strategy defining an IT roadmap.
B. You communicate the need for urgency. The projects already planned will be cancelled and the implementation of the new architecture vision will be set as first priority. A set of new projects will be defined to implement the new strategy. You will use the requirements from Phases B through D and define new projects for each one of the requirements. The use of defined interoperability architecture guidelines will then enable the project teams to work together and define a set of new point-to-point interfaces.
C. You describe the concept of Transition Architectures and clarify that the business value can be achieved by all the projects delivering their increments in a coordinated approach. Capability gaps and project dependencies are analyzed for each domain this will then enable the projects to be organized in work packages. You will then agree on the roadmap for the implementation and migration strategy meeting with all the key stakeholders.
D. You communicate the CIO's will to transform the corporation and then that he's seeking help from the domain architects to do that. The requirements are managed in order to enable every Architect to participate to the planning that will result in a detailed list of work activities with impact on the IT portfolio of projects. A five year Target Architecture will then be defined and a report will keep track of dependencies and factors assessment.

Scenario Please read this scenario prior to answering the question You are working as a consultant to the Chief Architect at a government agency responsible for securing all government communications and information systems. The agency has recently received funding for a program that will upgrade the reliability and performance of its secure communication systems which provide real-time, highly secure communication of voice, video, and message data to remote locations around the world.
The agency has an established enterprise architecture (EA) capability based on TOGAF 9. The Executive Director of the agency is the sponsor of the EA capability.
Since reliable, high-performance, and secure communications are essential to preserving national security,
the Executive Director has placed more stringent requirements for the architecture for the upgraded
system. It must be able to provide assurance and verification of specific performance measures on the key
services that are most crucial for system operation. Focusing on these service-level details and specific
measurements will allow more stringent requirements to be enforced in service contracts. It will also
provide a high degree of assurance that necessary performance is being delivered and that notifications
will occur if any critical service fails to perform as required.
A portion of the program budget has been allocated to conduct a review of the EA. The scope of the review
is to evaluate the processes, content and governance of the EA capability to ensure that the higher target
performance and service levels required by the upgraded system can be achieved.
The Chief Architecture has noted that the core EA artifacts that have been used since TOGAF 9 was
introduced are not adequate to describe these new capabilities. The artifacts do not have explicit
provisions for defining the in-depth measurement requirements regarding specific services required for the
system. She has learned that certain services within the current system have service measurement
implementations that match some of the new requirements, but they are only used in a few areas.
Recent EA efforts at another national agency have produced generalized high-performance
communication system models to realize similar requirements in a critical defense system involving secure
communications. It is possible that these models may be useful for the upgrade program.
Refer to the Scenario
You have been asked to make recommendations for tailoring the Architecture Content Metamodel to
accommodate the requirements of the upgraded system.
Based on TOGAF, which of the following is the best answer?
A. Since some artifacts will now require specific measurements and additional data will be needed to support the performance objectives linked to these measurements, you recommend that the motivation and governance extensions of the TOGAF 9 Content Metamodel are used. Using these extensions will allow modeling the goals, objectives and drivers for the architecture, linking them to service levels and more detailed governance models. This will also enable the ability to re-use existing profiles, customizing them for the various service contracts involved.
B. You recommend all of the TOGAF 9 Content Metamodel extensions be incorporated into the Architecture Content Metamodel. The full Content Metamodel will enable the EA team to capture and categorize all the important additional data needed to support the performance and measurement objectives linked to these artifacts. Once the new repository content has been implemented, on-demand queries can be used to generate a customized governance stakeholder view that isolates the artifacts and data needed to assess measurement for any particular service. If this view is found to be inadequate for the governance concerns, the service models within those artifacts can be expanded.
C. Since this case requires extensions of the modeling and data details of the service, this is best done by using the services extension of the TOGAF 9 Content Metamodel. By using this extension, the service model is no longer constrained by what is expected in typical business service definitions, allowing more flexibility for adding customized models to support the more stringent measurement requirements. The services extension can also be used to map terminology between the business services and the application components.
D. To support the type of stringent performance measurements needed for the more detailed governance views required for the upgraded system, the interfaces to the communication and network layer of the architecture must be highly visible at the application level. To accommodate the proper development of this, a Communications Engineering view should be created from the infrastructure extension models of the TOGAF Content Metamodel. This view will allow architects to align the required performance measurement communications across the system.
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 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.
B. 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.
C. 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.
D. 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.

Your role is that of a consultant to the Lead Enterprise Architect in a company that develops wind turbines for use in wind farms. The company has three manufacturing facilities, one in North America, one in Asia, and one in Europe. Each of these facilities supplies the power industry in its region.
The company recognizes that the long-term technical potential of wind energy can address the current global dependency on carbon fuels, in order to do so this will require wind turbines to be installed over the large areas and in areas of higher wind resources. In particular offshore wind farms can contribute substantially more energy than land stationed turbines.
The research arm of the company has pioneered the development of an offshore wind turbine design, with an improved turbine blade and power system, that will produce up to 20% more energy. This will allow the production of significantly more salable energy. This new design is ready to go into production.
The company has a mature Enterprise Architecture practice supported by a cross-functional Architecture Board and uses the TOGAF standard. The Chief Information Officer and the Chief Operating Officer cosponsor the Enterprise Architecture program.
As part of putting the new design into production, a pilot architecture project has defined an updated standard approach for controlling the automated test systems used to perform final quality assurance. The Chief Engineer, sponsor of the activity, and the Architecture Board have approved the plan for immediate implementation at each plant.
Architecture Contracts have been developed that detail the work needed to implement and deploy the new automated test system controller for each location. The Chief Engineer has expressed concern that a uniform process be employed at each location to ensure consistency and a low blade failure rate.
Refer to the Scenario
You have been asked to recommend the best approach to address the Chief Engineer's concern.
Based on the TOGAF standard, which of the following is the best answer?
A. You create an Architecture Contract to manage and govern implementation and migration process at each location. For internal development projects, you issue a memorandum of understanding between the Architecture Board and the implementation organization. Fir contracts issued to an external party, you ensure that it is a fully enforceable legal contract. You ensure that the Architecture Board reviews all deviations from the Architecture Contract, and considers whether or not to grant a dispensation to allow the implementation organization to customize the process to meet their local needs.
B. You create an Architecture Contract to manage and govern the implementation and migration process. If the contract is issued to an external party, you ensure that it is a fully enforceable legal contract. For internal development projects, you decide it is adequate to utilize a memorandum of understanding between the Architecture Board and the implementation organization. You recommend that if a deviation from the Architecture Contrast is detected, the Architecture Board grant a dispensation to allow the implementation organization the ability to customize the process to meet their local needs.
C. You review the applicable Architecture Contract for each location, ensuring that it addresses the project objectives, effectiveness metrics, acceptance criteria, and risk management. In cases where the contract is issued to an external party, you ensure that it is a legally enforceable contract. You schedule compliance reviews at key points in the implementation process to ensure that the work is proceeding in accordance with the Architecture Board reviews all deviations from the Architecture Contract, and considers whether or not to grant a dispensation to allow the implementation organization to customize the process to meet their local needs.
D. You use the Architecture Contracts to manage the architecture governance processes for the project across the locations. You deploy monitoring tools to assess the performance of each completed steam turbine at each location and develop change requirements if necessary. You recommend that if a deviation from the contract is detected the Architecture Board should modify the Architecture Contract to allow the implementation organization the ability to customize the process to meet their local needs. As a result, you then issue a new Request for Architecture Work to implement the modified Architecture Definition.

Your role is that of the Lead Enterprise Architect at a multinational automotive corporation. The company is headquartered in Germany, and manufactures cars, trucks and buses. It has manufacturing plants across North America, South America, Europe and Asia. Each of these plants has been operating its own planning and production scheduling systems, as well as custom developed applications that drive the automated production equipment at each plant.
The company has an ongoing initiative to improve the efficiency of all of its production operations, and in particular to reduce its carbon footprint. During a recent exercise held for internal quality improvement, it was determined that a significant reduction in energy usage could be achieved by replacing the current planning and scheduling systems with a common Enterprise Resource Planning (ERP) system located in one central data center. This central system would provide support to each of the plants replacing the functionality in the existing systems. It would also eliminate the need for full data centers at each of the plant facilities.
The Enterprise Architecture department has been operating for several years and has mature, well-developed architecture governance and development processes that are based on the TOGAF standard. At a recent meeting, the Architecture Board approved a Request for Architecture Work sponsored by the global CIO. The request covered the initial architectural investigations and the development of a comprehensive architecture to plan the transformation.
Refer to the Scenario
You have been asked to select the most appropriate recommendation to ensure that the team evaluated different approaches to the problem and clarifies the requirements for the architecture.
Based on the TOGAF standard, which of the following is the best answer?
A. The team should identify the individuals and groups within the organization who will contribute to the project, in order to understand who has concerns about the initiative. The team should then hold a series of interviews at each of the manufacturing plants using the business scenario technique. This will then enable them to identify and document the key high-level stakeholder requirements for the architecture.
B. The team should exercise due diligence and carefully research vendor literature and conduct a series of briefings with vendors that are on the current approved supplier list. Based on the findings from the research, the team should define a preliminary Architecture Vison. The team should then use that model to build concerns among the key stakeholders.
C. The team should perform a shallow architecture development iteration, developing Baseline and Target Architectures for each of the manufacturing plants. This should include development of a set of views corresponding to selected viewpoints that address key concerns of the stakeholders. A consolidated gap analysis between the architectures will then be used to validate the approach, and determine the capability increments needed to achieve the target state.
D. The team should utilize its approved supplier list, and conduct a pilot project that will enable those suppliers to demonstrate potential solutions that will address the concerns of the stakeholders. Based on the findings of that pilot project, a complete set or requirements will be developed that will drive the evolution of the architecture.
