The Open Group : OGEA-103 Questions & Answers

Please read this scenario prior to answering the question
You are the Lead Enterprise Architect at a major agribusiness company. The company ' s main harvest is lentils, a highly valued food grown worldwide. The lentil parasite, broomrape, has been an increasing concern for many years and is now becoming resistant to chemical controls. In addition, changes in climate favor the propagation and growth of the parasite. As a result, the parasite cannot realistically be exterminated, and it has become pandemic, with lentil yields falling globally.
In response to the situation, the CEO has decided that the lentil fields will be used for another harvest. The company will also cease to process third-party lentils and will repurpose its processing plants. Thus, the target market will change, and the end-products will be different and more varied.
The company has recently established an Enterprise Architecture practice based on the TOGAF standard as method and guiding framework. The CIO is the sponsor of the activity. A formal request for architecture change has been approved. At this stage there is no fixed scope, shared vision, or objectives.
Refer to the scenario
You have been asked to propose the best approach for architecture development to realize the CEO ' s change in direction for the company.
Based on the TOGAF standard which of the following is the best answer?

• A. You propose that this engagement define the baseline Technology Architecture first in order to assess the current infrastructure capacity and capability for the company. Then the focus should be on transition planning and incremental architecture deployment. This will identify requirements to ensure that the projects are sequenced in an optimal fashion so as to realize the change.
• B. You propose that the priority is to produce a new Request for Architecture Work leading to development of a new Architecture Vision. The trade-off method should be applied to identify and select an architecture satisfying the stakeholders. For an efficient change the EA team should be aligned with the organization ' s planning, budgeting, operational, and change processes.
• C. You propose that the team focus on architecture definition including development of business models, with emphasis on defining the change parameters to support this new business strategy that the CEO has identified. Once understood, the team will be in the best position to identify the requirements, drivers, issues, and constraints for the change.
• D. You propose that the team uses the architecture definition document and focus on architecture development starting simultaneously phases B, C and D. This is because the CEO has 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 change.

Refer to the table below:

• B. Taking major improvement decisions.
• C. Guiding effective change.
• D. Controlling the bigger changes.

You are employed as an Enterprise Architect working within the Enterprise Architecture (EA) team at an electric vehicle manufacturer. The company focuses on designing, manufacturing, and advancing battery technology for sustainable transportation, while also investing in charging infrastructure, autonomous driving systems, and renewable energy integration.
The company is introducing a major change to its vehicle design over a five-year period. This will be a cross-functional effort between hardware and software teams, delivering significant new features in the vehicles they manufacture. It is planned to be developed in phases. An architecture to support strategy has been completed with a roadmap for a set of projects.
The EA team has taken over the architecture for the hardware and software automotive platform used by current vehicles, some of which will be used again in the new vehicle design. The EA team has started to pick which parts of the architecture to use again.
The presentation and access to different variations of data that the company plans to offer through its vehicles creates a design challenge. The application portfolio and supporting infrastructure must connect with multiple cloud services and data repositories in different countries to be able to handle the data at a large scale.
Enough of the Business Architecture has been defined, so that work can commence on the Information Systems and Technology Architectures. Those architectures need to be defined to support the primary business services that the company plans to provide. These services will handle and use the data created by vehicles, preparing the way for self-driving vehicles in the future.
The company uses the TOGAF standard as the basis for its Enterprise Architecture framework. The EA team reports to the Chief Technical Officer (CTO), who is the sponsor of the EA program. The CTO requires that the EA team follow the purpose- based EA Capability model as described in the TOGAF Series Guide: A Practitioners ' Approach to Developing Enterprise Architecture Following the TOGAF ADM.
Refer to the scenario
How would you plan, organize, and manage the architecture development at this stage?
Based on the TOGAF standard which of the following is the best answer?

• A. Start an iteration of ADM Phase A, perform a Stakeholder Analysis, identifyingthe key stakeholders and revising the Architecture Vision. Update theStakeholder map created for the strategic architecture, so it reflects thestakeholders who are now the most important for the projects that are to bedeveloped.
  Hold a formal review with the CTO, who should decide whichprojects to include in the Architecture Roadmap and update the Implementationand Migration Plan to reflect the decisions.
• B. The superior architecture should be used to guide the approach. Review theidentified projects, dependencies, and potential overlaps, then decide the orderfor starting the projects. Develop high-level architecture descriptions. For eachproject determine how much work is needed, identify reference architectures,and candidate building blocks. Identify the resource needs, considering costand value.
  Document the different options, risks, and ways to control them toenable feasibility analysis and trade- off with the stakeholders.
• C. Architecture descriptions for the Application, Data, and TechnologyArchitectures should be developed at a suitable level to address the problems,and to identify the different options. For each project this includes identificationof candidate architecture and solution building blocks. Solution providersshould be identified, a readiness assessment performed, and an assessmentof the viability and fitness of the solution options. The results should be addedto the draft Implementation and Migration plan.
• D. Follow a standard pattern for cloud solutions that manage complex data, andwhich fits with the architecture to support strategy. Develop high-level TargetData, Application and Technology Architectures. Review the Architecture Visionto determine the level of detail, time, and scope of the ADM cycle phasesrequired for architecture development for the project. Identify and estimate thecost of the main work packages. Create an Architecture Roadmap and requestthe Architecture Board to approve the roadmap. Start the project.
