OG0-092 Practice Test

Scenario:

Please read this scenario prior to answering the question

Your role is consultant to the Lead Architect within a company that manufactures a variety of small electromechanical devices. The company is organized as independent operational divisions.

The company has a mature Enterprise Architecture practice and uses TOGAF standard for the basis of its architecture framework. In addition to the EA program, the company has a number of management frameworks in use, including business planning, portfolio/project management, and operations management. The EA program is sponsored by the CIO.

Each division has completed the Architecture Definition documentation required to tailor and configure the environment to meet its own specific manufacturing requirements.

The enterprise architects have analyzed the key corporate change attributes and implementation constraints. A consolidated gap analysis has been completed which has identified the gaps across the Business, Data, Application, and Technology domains.
Based on the results of the gap analysis, the architects have reviewed the requirements, dependencies and interoperability requirements needed to integrate the new ERP environment into the existing environment. The architects have completed the Business Transformation Readiness Assessment started in Phase A. Based on all of these factors they have produced a risk assessment.

The implementation process is estimated to take four years. Because of the risks posed by the complexity of the current environment, a phased approach is needed to implement the target architectures. The implementation and Migration Plan v0 1, the draft Architecture Roadmap, and the Capability Assessment deliverables are now complete.

Refer to the Scenario

You have been asked to recommend the next steps to prepare the final Implementation and Migration Plan.

Based on TOGAF standard, which of the following is the best answer?

A. You would apply the Business Value Assessment Technique to prioritize the implementation projects and project increments. The assessment should focus on return on investment and performance evaluation criteria that can be used to monitor the progress of the architecture transformation. You would confirm the Transition Architecture phases using an Architecture Definition Increments Table to list the projects. You would then document the lessons learned and generate the final plan.

B. You would assess how the plan impacts the other frameworks in use in the organization. The plan should be coordinated with the business planning, portfolio/project management and operations management frameworks. You would then assign a business value to each project, considering available resources and priorities for the projects. Finally, you would generate the Implementation and Migration Plan.

C. You would conduct a series of Compliance Assessments to ensure that the implementation team is implementing the architecture according to the contract. The Compliance Assessment should verify that the implementation team is using the proper development methodology. It should include deployment of monitoring tools and ensure that performance targets are being met. If they are not met, then changes to performance requirements should be identified and updated in the Implementation and Migration Plan.

D. You would place the strategic Architecture Definition and Transition Architectures under configuration control as part of the ongoing architecture development cycle. This will ensure that the architecture remains relevant and responsive to the needs of the enterprise. You would then produce an Implementation Governance Model to manage the lessons learned prior to finalizing the plan. You recommend that lessons learned be accepted by the Architecture Board as changes to the architecture without review.

You are serving as the Lead Architect for a chain of convenience stores, operating as a franchise, which has over 5000 retail outlets throughout the Asia-Pacific region. The stores operate 24 hours a day and 7 days a week and rely on point-of-sale technology to manage their inventory.

Stores place all orders on-line. The back-office systems collect real-time data to support ordering and product selection decisions including the tailoring of product assortment based on sales history, customer demographics as well as the next day's weather forecast. In many cases, several stores are located in neighboring areas. This strategy makes distribution to each store cheaper, as well as making multiple deliveries per day possible.

An Enterprise Architecture practice exists within the company, with the CEO and CIO as joint sponsors. They have decided to adopt TOGAF 9 within the practice and the first project is to restructure the Enterprise Architecture so that it can better accommodate the changing strategies within the company and also better respond to changes in economic and technical environments.

The CIO has stated that the following issues need to be addressed in the restructuring:

The systems should be able to withstand any unforeseen disruptions which might affect day to day operations. This is highly critical for ensuring high levels of customer satisfaction and maintaining and growing revenue.
Dependencies between the application components, the application platform, and technology infrastructure should be minimal and well defined. This will facilitate scalability and ease of enhancement of the service offerings.
The company is adopting the ARTS Operational Data Model and Data Warehouse Model from the National Retail Federation. This will address past problems with data quality and inconsistent data.
To remain competitive, new products and promotions must undergo market trials and if these are successful, deployed across the retail chain. Information systems must be able to manage changes and updates without undue delays.

Refer to the Scenario

[Note: You should assume that the company has adopted the example set of principles that are listed and defined in TOGAF, Section 23.6. You may need to refer to Chapter 23 of the reference text in order to answer this question.]

You have been asked to identify the most relevant architecture principles for the current situation.

Based on TOGAF, which of the following is the best answer? [Note: The ordering of the principles listed in each answer is not significant.]

A. Interoperability, Data is Accessible, Data is Shared, Requirements Based Change, Control Technical Diversity

B. Technology Independence, Business Continuity, Common Vocabulary and Data Definitions, Data Trustee, Responsive Change Management

C. IT Responsibility, Data Security, Ease of Use, Requirements Based Change, Common Use Applications

D. Interoperability, Maximize Benefit to the Enterprise, Data Trustee, Data is an Asset, Responsive Change Management

Scenario: Armstrong Defense Industries

Please read this scenario prior to answering the question

Armstrong Defense Industries is the prime contractor for the Dreadnought Unmanned Aircraft System program.

Over the course of this contract, the company has grown rapidly by acquisition and has inherited numerous different procurement processes and related IT systems. Armstrong Defense is moving aggressively to consolidate and reduce redundant procurement processes and systems. The CEO has announced that the company will seek to leverage higher volume discounts and lower related IT support costs by instituting a preferred supplier program.

To achieve this goal, Armstrong Defense needs to define Baseline and Target Architectures. These architectures must address key stakeholders concerns such as:

1. What groups of people should be involved in procurement-related business processes?
2. What current applications do those groups use?
3. Which procurement-related business processes are supported by zero, one, or many existing applications?
4. What are the overall lifetimes of the Request for Proposal and Purchase Order business objects?
5. What non-procurement applications will need to be integrated with any new procurement applications?
6. What data will need to be shared?
At present, there are no particularly useful architectural assets related to this initiative. All assets need to be acquired and customized or created from scratch. The company prefers to implement existing package applications from systems vendors with little customization.

The architecture development project has just completed its Architecture Context iteration cycle and is about to begin the Architecture Definition iteration cycle.

Armstrong Defense is using TOGAF for its internal Enterprise Architecture activities. It uses an iterative approach for executing Architecture Development Method (ADM) projects.

MightyGears 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 an agreed target architecture. Final decisions on the solutions are not yet fully agreed. They have completed the first pass architecture and now are looking at the best opportunities and solutions to meet their financial goals.

You are the Chief Architect from a consulting organization brought into review the work to date by MightyGears and to make recommendations to the CIO and the board on the opportunities and solutions present.

Refer to the scenario above

Which of the following answers best describes how TOGAF recommends examining the opportunities and solutions before presenting to the board?

Choose one of the following answers

A. I would examine the architecture work today ensuring it is complete and accurate and addressing any gaps. I would look at functional and integration requirements. I would then ensure all dependencies are understood and documented. I would then create the necessary artefacts including major work packages and transition architectures and the project charters for the recommended projects for presentation to the board.

B. I would assess the architecture work today, create, and priorities projects to transition Widget Inc from the current architecture to target architecture. This will include a business value for each project, the resources required and the intended timing. I would then validate the prioritizations with the board particularly looking at cost benefits and risks. Lastly, I would generate the Architecture Implementation Roadmap and document lessons learned.

C. I would assess the requirements of the organization particularly those requirements describing the functions required and information flows within the architecture. 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.

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.

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.
