The Open Group OGEA-103 Exam With Confidence Using Practice Dumps

The correct answer is C, as it aligns with the TOGAF ADM approach and best practices for organizing architecture work in a phased and structured manner.

Analysis of the Correct Answer (Option C):

Identifying Projects, Dependencies, and Synergies

The scenario describes a phased approach to vehicle development over five years.

Identifying dependencies ensures a logical and structured rollout of technology and business capabilities.

Developing High-Level Architecture Descriptions

Since Business Architecture is already defined, it is now time to develop high-level descriptions of Information Systems and Technology Architectures.

TOGAF emphasizes incremental and iterative refinement, meaning that starting with high-level descriptions is a logical first step.

Determining Workload and Resource Allocation

TOGAF ADM Phase B, C, and D involve creating architecture descriptions.

Understanding how much work is required ensures efficient resource planning and allocation.

Identifying Reference Architectures and Building Blocks

Using reference architectures and reusable architecture building blocks (ABBs) is a key best practice in TOGAF.

This enables efficiency and consistency in architecture development.

Evaluating Costs, Risks, and Feasibility

TOGAF emphasizes a risk-aware approach to enterprise architecture.

Documenting options, risks, and control measures ensures feasibility before execution.

Why Other Options Are Incorrect?

Option A: Initiating ADM Phase A Again

Incorrect because the scenario states that the Architecture Vision has already been completed.

Phase A is used for initial vision-setting, but at this point, the focus is on executing defined architectures.

Option B: Researching Data Companies for Target Architecture Development

Incorrect because the focus should be on defining internal architectures rather than external research.

While benchmarking best practices can be useful, it is not the primary activity at this stage.

Option D: Studying Other Companies and Performing Readiness Assessment

Incorrect because the focus should be on leveraging the organization ' s existing architecture and resources.

Solution provider readiness assessments are typically part of procurement, not enterprise architecture development.

The TOGAF standard divides Enterprise Architecture into four primary architecture domains: business, data, application, and technology. These domains represent different aspects of an enterprise and how they relate to each other. The business domain defines the business strategy, governance, organization, and key business processes. The data domain describes the structure of the logical and physical data assets and data management resources. The application domain provides a blueprint for the individual applications to be deployed, their interactions, and their relationships to the core business processes. The technology domain describes the logical software and hardware capabilities that are required to support the deployment of business, data, and application services. Other domains, such as motivation, security, or governance, may span across these four primary domains. References:

TOGAF and the history of enterprise architecture | Enable Architect

The Preliminary Phase is the phase in TOGAF where an organization establishes or enhances its Enterprise Architecture Capability. This includes defining governance structures, roles, responsibilities, processes, tools, and architectural principles. The objective is to prepare the organization to successfully execute the ADM.

Phase A focuses on Architecture Vision for a specific initiative, not on creating the overall EA capability. Phase G deals with implementation governance, and Phase H focuses on architecture change management. None of these phases are responsible for establishing the EA practice itself.

The Preliminary Phase answers foundational questions such as how architecture will be governed, who owns architecture decisions, how compliance will be enforced, and how architecture work will be integrated with other organizational processes. Therefore, creation of an Enterprise Architecture Capability clearly belongs to the Preliminary Phase.
