Exam OGEA-102 Topic 1 Question 29 Discussion

The correct answer is C, as it aligns with the key TOGAF principles necessary for guiding enterprise architecture in a merger scenario where retail operations and systems are being consolidated.
Analysis of the Principles in Option C:
Common Use Applications
Since the two companies are merging, it is essential to standardize applications across the enterprise.
Using common applications ensures consistency, reduces costs, and improves efficiency.
TOGAF emphasizes this principle to prevent duplicate or redundant systems, which aligns with the CIO's goal of reducing the number of applications used.
Data is an Asset
In the scenario, a central inventory management system is a core business function.
Treating data as an asset ensures it is managed properly, shared efficiently, and used strategically across the merged organization.
This principle supports the company's ability to predict demand, adjust stock levels, and automate reordering.
Common Vocabulary and Data Definitions
The merger requires integrating different systems and data structures.
Having a common vocabulary ensures that all stakeholders (stores, fulfillment centers, and digital platforms) use consistent terminology and data definitions.
This minimizes confusion and ensures interoperability across business functions.
Maximize Benefit to the Enterprise
Every architectural decision should focus on the overall benefit to the business.
By consolidating IT systems and reducing redundancies, the company achieves cost savings, which directly supports this principle.
Business Continuity
The stores operate seven days a week, so system changes must ensure uninterrupted service.
Business continuity ensures that customers are not affected during the transition and that critical retail operations (sales, inventory tracking, and fulfillment) remain functional.
Why Other Options Are Incorrect?
Option A: Control Technical Diversity, Interoperability, Data is an Asset, Data is Shared, Business Continuity Control Technical Diversity is not the primary concern here. The focus is on system consolidation, not necessarily on limiting technology diversity.
Interoperability is important but not as critical as defining a common system and data structure.
Option B: Service Orientation, Compliance with the Law, Requirements-Based Change, Responsive Change Management, Data Security While service orientation and compliance are valuable, they are not the most relevant to this specific business transition.
Change management and data security are important but do not address the primary enterprise-wide architectural concerns of system consolidation.
Option D: Ease of Use, Common Use Applications, Data is an Asset, Technology Independence, Business Continuity Ease of Use is beneficial but is not a core architecture principle in this case.
Technology Independence is useful but does not align directly with the scenario's priority, which is consolidating applications and data structures.
