The Open Group OGEA-10B Exam - Topic 1 Question 3 Discussion

Actual exam question for The Open Group's OGEA-10B exam

Question #: 3
Topic #: 1

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?

AYou 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.

BYou 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.

CYou 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.

DYou 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.

Show Suggested Answer

Suggested Answer: D

A Request for Architecture Work is a document that describes the scope, approach, and expected outcomes of an architecture project. A Request for Architecture Work is usually initiated by the sponsor or client of the architecture work, and approved by the Architecture Board, which is a governance body that oversees the architecture work and ensures compliance with the architecture principles, standards, and goals.A Request for Architecture Work triggers a new cycle of the Architecture Development Method (ADM), which is the core process of the TOGAF standard that guides the development and management of the enterprise architecture12

An Architecture Vision is a high-level description of the desired outcomes and benefits of the proposed architecture. An Architecture Vision is the output of Phase A: Architecture Vision of the ADM cycle, which is the first phase of the architecture development. An Architecture Vision defines the scope and approach of the architecture work, and establishes the business goals and drivers that motivate the architecture work.An Architecture Vision also involves obtaining the approval and commitment of the sponsors and other key stakeholders, and initiating the Architecture Governance process3

A trade-off analysis is a technique that can be used to evaluate and compare different architecture alternatives and select the most suitable one. A trade-off analysis involves identifying the criteria and factors that are relevant to the decision, such as costs, benefits, risks, and opportunities, and assessing the strengths and weaknesses of each alternative. A trade-off analysis also involves balancing and reconciling the multiple, often conflicting, requirements and concerns of the stakeholders, and ensuring alignment with the Architecture Vision and the Architecture Principles.

Therefore, the best answer is D, because it proposes the best approach for architecture development to realize the CEO's change in direction for the company. The answer covers the Request for Architecture Work, the Architecture Vision, and the trade-off analysis techniques that are relevant to the scenario.

Surprised they’re shifting away from lentils entirely, is that really the best move?

I like the idea in option D about aligning with planning and budgeting, but I’m not clear on how the trade-off method would actually help us select the right architecture in this scenario.

Option C sounds appealing because it emphasizes developing business models first, but I wonder if we might miss some technical requirements by not focusing on the architecture right away.

I think option B could work since it suggests starting multiple phases at once, but I’m a bit worried about how chaotic that might get without a clear scope.

I remember we discussed the importance of understanding the current architecture before making changes, so option A seems reasonable, but I'm not entirely sure if starting with the baseline is the best first step.

Option A sounds like a solid approach to me. Assessing the current technology infrastructure and planning the transition in a step-by-step way seems like the most pragmatic solution given the scope of change involved.

I'm a bit confused by all the different TOGAF phases mentioned. I think I'd lean towards option D - starting with a new Request for Architecture Work and developing a clear Architecture Vision. That seems like the best way to get aligned with the organization's overall planning and change processes.

This seems like a tricky one. I'd probably start by focusing on the business models and change parameters, as option C suggests. Understanding the new strategy and requirements is key before diving into the technical details.

I'm torn between B and C. On one hand, tackling multiple phases in parallel could help speed up the process. But I also see the value in really nailing down the business requirements first before diving into the technical details. Tough call, but I'm leaning towards C.

I think when you set that property to false, it means you skip the setup wizard, but I'm not sure if that affects the admin account creation.

The key here is to understand what the "pkg update" command actually does. Based on my experience, it updates all packages that have updates available, but it doesn't touch the kernel. So I think the correct answer is option B.

Option B seems a bit too rushed. We need to take the time to properly define the baseline architecture before moving forward.

Haha, I'm just hoping the CEO doesn't decide to switch to growing broomrape instead. That would really throw a wrench in the works!
