Scenario:
Please read this scenario prior to answering the Question
Your role is that of Lead Enterprise Architect within a vacation property management firm that has been growing through acquisition. The firm manages over 200 resort properties across North America. Many of the resort properties use the same internal IT systems that they used before they were acquired. Until recently, the only requirement that has been placed on each property is that they use a standard financial reporting system to report their financial results to the headquarters on a weekly basis.
The CEO has stated his concerns about the inefficiencies of the current approach and identified the need to change. He has defined a new strategic vision that will enhance the business by standardizing its operations across the network to provide consolidated financial, human resources, logistics, sales and marketing, and yield management. He has also stated that he expects results by the end of the current fiscal year.
These changes will provide the company with improved utilization of its capacity 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 into key markets to improve yields.
The firm has a mature enterprise architecture practice 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 firm, including detailed requirements and recommendations.
Based on the recommendations from the initial study, the firm has taken the decision to adopt a packaged suite of integrated applications that is tailored to the needs of the hospitality industry.
Refer to the scenario
You have been asked by the Chief Architect to justify the best approach for architecture development to realize the CEO's vision.
Based on TOGAF 9, which of the following is the best answer?
A. You recommend that the target architecture is defined first, followed by transition planning. This is because the vision is well understood and the strategic architecture agreed. This 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.
B. You recommend that this engagement define the baseline Technology Architecture first in order to assess the current infrastructure capacity and capability. Then the focus should be on transition planning and architecture deployment. This will identify retirements to ensure that the projects are sequenced in an optimal fashion so as to realize the vision.
C. You recommend 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.
D. You recommend 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.

You have been asked to recommend the approach to identify the work packages that will be included in the Transition Architecture(s).
Based on the TOGAF standard, which of the following is the best answer?
A. You would document the factors impacting the Implementation and Migration Plan and group the gaps identified in the domain architecture gap analysis results. For each gap, you would identify a proposed solution and classify it as a new development, purchased solution, or based on an existing product. You would group similar solutions together to form work packages, and identify dependencies between the work packages factoring in the clinical trial schedules. Finally, you would regroup the packages into a set of Capability increments scheduled into a series of Transition Architectures.
B. You would use a Consolidated Gaps, Solutions and Dependencies Matrix as a planning tool. For each gap, you would classify whether the solution is either a new development, purchased solution, or based on an existing product. You would group the similar solutions together to define the work packages.
You would then regroup the work packages into a Set of Capability Increments to transition to the Target Architecture taking into account the schedule for clinical trials.
C. You would determine the set of Solution Building Blocks required by identifying which need to be developed and which need to be procured. You would eliminate any duplicate building blocks, and then group the remaining Solution Building Blocks together to create the work packages using a CRUD matrix. You would then rank the work packages in terms of cost, and select the most cost-effective options for inclusion in a series of Transition Architectures. Finally, you would schedule a sequential roll out of the work packages across the geographic regions.
D. You would group the Solution Building Blocks from a Consolidated Gaps, Solutions and Dependencies Matrix into a set of work packages. Using the matrix as a planning tool, you would then regroup the work packages to account for dependencies. You would sequence the work packages into the Capability Increments needed to achieve the Target Architecture. You would schedule the rollout one region at a time. Finally, you would document the progression of the Enterprise Architecture using a state evolution table.

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 that in Phase E, the team determines an approach to implementing an overall strategic direction that will address and mitigate the risks identified.
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 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.

You are working as a consultant to the Chief Architect at an intelligent and security organization responsible for securing government communications and information systems. These provide real-time, highly secure communication of voice, video, and message data to remove locations around the world. The agency has recently received information from intelligence sources that the current encryption protocols may no longer be secure. In response, a program is underway to upgrade the systems.
The agency has an established Enterprise Architecture (EA) capability based on the TOGAF standard. The Executive Director of the agency is the sponsor of the EA capability.
Since reliable, high-preformcane, and secure communications are essential to be preserving national security, the Executive Director has placed stringent requirements for the architecture of the upgraded systems. It must be able to provide assurance of the upgraded systems. 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 stricter 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 Architect has noted that the core EA artifacts that have been in use are not able 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 implemenations 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.
[Note: You may need to refer to the Content Metamodel chapter, section 30.4 (located in Part IV) of the reference text in order to answer this question.] You have been asked to make recommendations for tailoring the Architecture Content Metamodel to accommodate the requirements of the upgraded system.
Based on the TOGAF Standard, Version 9.2, which of the following is the best answer?
A. You recommend that a Communications Engineering view is created using the infrastructure consolidation extension from the Architecture Content Metamodel. This view will allow architects to align the needed performance measurement communications across the system. This will support the stringent performance measurements needed for the more detailed governance views required for the upgraded system, making the interfaces to the communication and network layer of the architecture highly visible at the application level.
B. You recommend that the services extension be incorporated into the Architecture Content Metamodel.
By using this extension, the service model is no longer constrained by what is expected in typical business service defintions, 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.
C. You recommend that the motivation and governance extensions are incorporated into the Architecture Content Metamodel. Using these extensions will allow modeling the goals, objectives and drivers for the architecture, linking them to servive 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.
D. You recommend all of the 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 neded 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 isolated 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 servie models within those artifacts can be expanded.
