OGEA-101 Exam Dumps - The Open Group Enterprise Architecture Questions and Answers

An Enterprise Architecture Capability is the ability of the organization to perform effective and efficient architecture work, including the definition, governance, and management of its architectures2. The Preliminary Phase involves the following activities1:

•Reviewing the organizational context, scope, and drivers for conducting Enterprise Architecture

•Establishing the Architecture Capability desired by the organization, including the maturity level, roles, responsibilities, processes, and tools

•Defining and establishing the Organizational Model for Enterprise Architecture, which describes how the architecture function is organized and integrated within the enterprise

•Defining and establishing the Architecture Governance framework, which provides the mechanisms for ensuring the quality, consistency, and compliance of the architecture work

•Selecting and implementing the tools that support the Architecture Capability, such as repositories, modeling tools, and communication tools

•Defining the Architecture Principles that will guide and constrain the architecture work, based on the business principles, goals, and drivers of the organization

•Defining the Organization-Specific Architecture Framework, which is an adaptation of the generic TOGAF ADM to suit the specific requirements, standards, and practices of the organization

The Preliminary Phase is essential for preparing the organization for the successful development and implementation of its architectures, as well as for ensuring the alignment of the architecture work with the business strategy and objectives1.

Comprehensive and Detailed Explanation From documents:

In TOGAF, a Business Scenario is an ADM technique used to capture and structure business requirements in a way that directly informs the development and validation of architectures. It frames a specific business problem (or opportunity) and articulates the desired outcomes/objectives, along with the business and technical context, the involved actors and roles (human and system), and the measures of success. This makes option A correct because it concisely captures the essence of a Business Scenario: a well-defined business problem coupled with the outcomes the business seeks to achieve.

A good Business Scenario typically includes:

The business problem/opportunity and drivers.

The business and technical environment/context in which the problem exists.

The desired outcomes/objectives and measures of success (how success will be recognized).

Actors and roles (both human and system) and their interactions.

Capabilities and high-level requirements implied by the scenario.

Business Scenarios are especially valuable in Phase A: Architecture Vision to validate scope, objectives, and business value, and they continue to be used throughout Phases B–D to test and validate the target architectures and to maintain requirements traceability via Requirements Management. They promote shared understanding among stakeholders and provide a concrete basis for evaluating solution options and assessing architecture fitness-for-purpose.

Why the other options are incorrect:

B. A use-case for developing a business model. While Business Scenarios and use-cases are related, a Business Scenario is broader. It provides context, problem, objectives, and measures of success; use-cases are often derived from or complement Business Scenarios to specify interactions, but a Business Scenario is not merely a use-case.

C. A method to quantify readiness for change. This describes Business Transformation Readiness Assessment, a separate TOGAF technique used to gauge an organization’s readiness to execute change. It is not what TOGAF defines as a Business Scenario.

D. A technique to identify differences between a baseline and a target architecture. That is Gap Analysis, another distinct ADM technique used to determine what needs to change to move from the current state to the desired future state.

The Implications section describes the impact of adhering to the principle on the organization, the processes, the information systems, and the technology23. It also identifies the changes, costs, and risks that may result from applying the principle23. The Implications section helps to communicate the benefits and consequences of the principle to the stakeholders and to guide the implementation and governance of the architecture23.

The other sections of the TOGAF template for Architecture Principles are1:

•Name: This section provides a short and memorable name for the principle that represents its essence and purpose23. The name should not mention any specific technology or solution23.

•Statement: This section provides a concise and formal definition of the principle that expresses the fundamental rule or constraint that the principle imposes23. The statement should be clear, unambiguous, and testable23.

•Rationale: This section provides the reasoning and justification for the principle, explaining why it is important and how it supports the business goals and drivers23. The rationale should also link the principle to the higher-level enterprise or IT principles that it elaborates on23.
