The Open Group OGEA-103 Question Answer

Please read this scenario prior to answering the question

You are employed as an Enterprise Architect at a leading global technology enterprise

specializing in digital infrastructure, cloud computing, and data-centric innovation. The

company provides a vast ecosystem of platforms that serve billions of users across

the globe. These platforms span online marketplaces, advanced advertising networks,

Al-driven services, productivity tools, and digital entertainment experiences.

The senior leadership within the company is worried about the company's ability to

address all the opportunities around artificial intelligence (Al). They feel that the

business is at risk of falling behind its competitors, and that significant changes are

necessary for the business to remain competitive. Most senior leaders feel that the

operations need to be more efficient, and the organization needs to change to achieve

its future goals.

The company has an established Enterprise Architecture (EA) program based on the

TOGAF standard, sponsored jointly by the Chief Information Officer (CIO) and senior

executives. In your role as an Enterprise Architect within the EA team, you work

closely with the business stakeholders in the company as well as the sponsors.

The CEO has decided that reorganizing its subsidiaries around artificial intelligence

and machine learning will improve the way the company creates and delivers value.

The sponsors have approved a project for the reorganization which is being led by the

EA team.

The EA team have developed a strategic architecture which has been approved by

the sponsors. It includes an Architecture Vision, and high-level definitions of the

domain architectures. This sets out a plan over a multi-year period and covers three

distinct transformations to implement the reorganization.

The sponsors have read reports that the majority of transformation projects dealing

with digital and artificial intelligence are failing. They have made it clear that prior to

the approval of the detailed Implementation and Migration plan, the EA team needs to

address the risks associated with the reorganization. They want assurance that the

reorganization will succeed and deliver the promised increases in value for the

business.

Refer to the scenario

The EA team leader has asked how you would address the request from the

sponsors.

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

Before preparing the detailed Implementation and Migration plan, you wouldreview and consolidate the gap analysis results from Phases B to D. Thisenables you to evaluate the implications related to potential solutions and inter-dependencies. It is used to identify the transformations required to achieve theproposed Target Architecture. You then assess the readiness of theorganization to undergo change and determine an overall direction to r

Explanation:

In this scenario, the strategic architecture is already complete and approved, and the sponsors now want assurance about risks before approving the detailed Implementation & Migration Plan. According to TOGAF, this work occurs in Phase E: Opportunities & Solutions and Phase F: Implementation & Migration, where a key activity is performing Business Transformation Readiness Assessment and Risk Assessment before finalizing the roadmap and migration plan.

Option C aligns exactly with TOGAF guidance for this stage:

Why Option C is correct

1. It starts with assessing organizational readiness for change

TOGAF Phase E requires evaluation of Business Transformation Readiness, addressing:

Organizational capability

Cultural readiness

Skills and capacity

Sponsorship and governance

This is exactly what Option C describes:

“assess how ready the organization is to change.”

This directly responds to the concern in the scenario that “most senior leaders feel the operations need to be more efficient” and that “significant changes are necessary.”

2. It includes identification and classification of risks

TOGAF requires performing a Risk Assessment before migration planning, ensuring risks are categorized, documented, and mitigation strategies defined.

Option C includes:

“identification and classification of the risks … together with an approach to mitigate the risks.”

This is precisely what the sponsors requested: clear management of risks before approving migration planning.

3. It ties risk, dependencies, and gaps directly into the Implementation & Migration Plan

TOGAF requires identifying:

Dependencies between work packages

Gaps between baseline and target

Required actions to improve readiness

Work package sequencing

Option C states:

“identifying dependencies between the set of changes, including gaps and work packages… identifying improvement actions to be worked into the Implementation and Migration Plan.”

This matches TOGAF Phase E and F activities exactly.

4. It evaluates business value, effort, and risk for each transformation

The scenario involves three distinct transformations, and sponsors want assurance of value delivery. TOGAF Phase F includes Consolidated Gaps, Solutions, and Dependencies and migration prioritization based on value, cost, and risk.

Option C states:

“The business value, effort, and risk associated for each transformation should then be identified and documented.”

This is directly aligned to the TOGAF-required migration prioritization criteria.

Why the other options are incorrect

A – Focuses on gap analysis only

Gap analysis was performed during Phases B–D, and while relevant, Option A does not emphasize risk, readiness, or assurance—key concerns of the scenario.

B – Misrepresents TOGAF (organizational requirements matrix is not a formal TOGAF artifact)

Also, it incorrectly focuses on aligning change with the operating model, which TOGAF does not prescribe as the primary risk-mitigation activity.

D – Focuses on architectural alternatives; the target architecture is already approved

The scenario states the strategic architecture is complete and approved—there is no need to revisit alternatives. This is misaligned with the starting point of the question.

Conclusion

Option C is the only answer that conducts:

Business transformation readiness assessment

Risk identification and mitigation

Dependencies, gaps, and work package analysis

Integration of risks and improvement actions into migration planning

This matches precisely what TOGAF expects at this stage and what the sponsors requested.
