The Open Group OG0-092 Exam Preparation Materials

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 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.

C. 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. This will ensure that the change can be defined in a structured manner and address the requirements needed to realize the vision.

D. 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.

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.

Please read this scenario prior to answering the question You are serving as the Lead Architect for a chain of convenience stores, which has over 2000 retail outlets throughout the Asia-Pacific region. The stores operate 24 hours a day and 7 days a week and use the latest 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 9 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 also 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.

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.]
