Question 112

Scenario:

Please read this scenario prior to answering the question

Your role is that of Lead Enterprise Architect working at the headquarters of a fast food chain. The chain manages over 7500 restaurants across 33 countries. Each restaurant in the chain is an independently owned and operated franchise.

Many of the restaurants still use the first generation IT systems deployed over 10 years ago. The Chief Operating Officer (COO) 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 including providing its franchisees new support services to help them address the increasing competition from coffee shops. This 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.

The changes will help provide the chain with improved products, including healthier alternatives in the 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 the TOGAF standard 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 COO’s vision. This recently completed with approval of a strategic architecture encompassing the entire chain, including detailed requirements and recommendations.

Based on the recommendation from the initial study, the decision has been taken for the chain to adopt a packaged suite of integrated application 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 COO’s vision.

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

Options:

You propose that the target architecture is defined first 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.

You propose that the baseline Technology Architecture is defined first in order to assess current infrastructure capacity and capability. 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.

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.

You propose that the focus be placed on architecture definition, with emphasis on understanding the strategic change parameters. The requirements, drivers, issues and constraints for this engagement can then be identified. You would ensure that the target architecture addresses not functional requirements so as to ensure the target architecture is robust and secure.

Question 113

Scenario:

Please read this scenario prior to answering the Question.

The ABC company 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 AirLight, a competitor, because of superior customer service. The company actually has better coverage in nearly all markets than AirLight, 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. The company 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 Executive Council has stated that the program should define specific initiatives to enable each regional business unit to create an implementation of the Customer Service System. The implementation must meet the needs of the business unit and still provide the information needed to enable major improvements to the customer.

Refer to the Scenario

You are serving as the Lead Architect for the Performance and Integrity project of the Customer Service System program.

The project has been chartered to address the architecture(s) required to support the Customer Service System from an infrastructure perspective. At the present time, the project team is conducting an architecture development project that is focused on the customer self-service capability, which was defined as part of the earlier strategic planning activities. This capability will enable customers to access their accounts, pay bills, request account reviews, and provision services from any web-enabled device.

The project team has gathered information about the self-service capability, developed a business scenario, and used the results to define an Architecture Vision for achieving the capability.

You have been asked to recommend the course of action to complete the project.

Based on TOGAF 9, which of the following is the best answer?

Options:

In the remaining architecture definition phases, the project team should map out the capability in the Technology domain. In Phases E and F, the capability should be broken down into a set of Solution Building Blocks that define the Target Architecture. Where possible, the Solution Building Blocks should be drawn from the Architecture Repository.The completed Architecture Definition Document and the Implementation and Migration Plan will be

Question 114

Scenario

Please read this scenario prior to answering the question

You are serving as the Lead Enterprise Architect for a chain of convenience stores. The stores operate 24 hours a day and 7 days a week and use cloud-based point-of-sale (POS) technology to manage their sales and inventory. Cloud-based POS systems store all user data, including sales and inventory in a remote server.

The cloud-based 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. The stores also act as self-service delivery locations for a large online retailer which further increases the number of potential customers entering the stores.

An Enterprise Architecture practice exists within the company, with the CEO and CIO as joint sponsors. They have decided to adopt TOGAF standard within the practice and the first project is to restructure the Enterprise Architecture so that it can better support the existing environment and accommodate future changes of strategy within the company.

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

They need to address problems with data quality and inconsistent data in order to support better decision making and analysis.

The architecture should focus on the needs of the business, not technology

To remain competitive, new products and promotions must undergo market trials before deployment across the retail chain. Information systems must be able to manage changes and updates without undue delays.

[Note: You should assume that the company has adopted the example set of principles that are listed and defined in TOGAF standard, Architecture Principles chapter. You may need to refer to the Architecture Principles chapter, section 20.6 (located in Part III) within 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 the TOGAF standard, which of the following is the best answer? [Note: The ordering of the principles listed in each answer is not significant.]

Options:

Requirements Based Change, Responsive Change Management, Data Trustee, Common Vocabulary and Data Definitions, Business Continuity

IT Responsibility, Data Security, Ease of Use, Service Orientation, Common Use Applications

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

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

Question 115

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 context 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?

Options:

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 a

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 needs 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 stakeh

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

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 w
