The Open Group TOGAF Business Architecture Foundation Exam OGBA-101 Exam Dumps: Updated Questions & Answers (November 2025)

In TOGAF ADM, Phase B is the Business Architecture phase where the architect should locate existing architecture descriptions to create an information map. This phase involves developing a detailed understanding of the business environment, including business processes, roles, and information flows. Existing architecture descriptions provide a baseline for identifying how information is currently managed and how it can be optimized to support business objectives.

The table describes the steps involved in Phase B (Business Architecture), Phase C (Information Systems Architectures), and Phase D (Technology Architecture) of the TOGAF ADM5. These phases are responsible for developing the target architectures for each domain and identifying the gaps between the baseline and target architectures. The table shows the outputs and outcomes of each phase, as well as the essential knowledge required for each phase.

The table describes the iterative cycle of defining requirements, identifying gaps, and creating solutions that occurs throughout the architecture development phases of the TOGAF ADM. This cycle is most prominent in:

Phase B (Business Architecture):

Develop the Business Architecture, identifying gaps between the baseline and desired business capabilities, processes, and information flows.

Define work packages to address these gaps and realize the target business architecture.

Phase C (Information Systems Architectures):

Develop the Data and Application Architectures to support the Business Architecture.

Identify gaps between the baseline and target information systems architectures.

Define work packages to address these gaps and realize the target data and application architectures.

Phase D (Technology Architecture):

Develop the Technology Architecture to support the Data and Application Architectures.

Identify gaps between the baseline and target technology architectures.

Define work packages to address these gaps and realize the target technology architecture.

Risk Management is the discipline that addresses the identification, assessment, and prioritization of risks followed by coordinated application of resources to minimize, control, and monitor the impact of unfortunate events or to maximize the realization of opportunities. It is about striking a balance between the positive outcomes of opportunities and the negative outcomes of risks, ensuring that the enterprise can achieve its objectives while keeping potential threats under control.

When developing the Architecture Vision, it is essential for the architect to examine and search for Value Streams and Business Capabilities. Here’s a detailed explanation:

Architecture Vision Phase (Phase A):

The Architecture Vision phase sets the overall direction and context for the architecture project. It defines the scope and vision for the future state architecture and establishes a shared understanding among stakeholders.

Value Streams:

Definition: Value streams represent the end-to-end set of activities that deliver value to customers or stakeholders. They provide a high-level view of how value is created and delivered within the organization.

Importance: Understanding value streams helps in aligning the architecture with business processes and ensuring that the architecture supports the delivery of value.

Business Capabilities:

Definition: Business capabilities define what an organization needs to be able to do to achieve its business objectives. They represent the core functions or abilities of the organization.

Importance: Identifying and understanding business capabilities is crucial for ensuring that the architecture addresses the critical functions of the business and supports its strategic goals.

TOGAF ADM References:

Phase A: Architecture Vision: In this phase, the architect examines value streams and business capabilities to understand the current state and define the desired future state. This helps in creating an architecture vision that is aligned with business objectives and supports value creation.

Strategic Planning: Value streams and business capabilities provide a foundation for strategic planning, ensuring that the architecture is designed to support key business activities and capabilities.

In summary, when developing the Architecture Vision, examining value streams and business capabilities is essential for understanding how the organization delivers value and ensuring that the architecture supports critical business functions and strategic objectives.

When developing a Business Architecture, TOGAF provides guidance on how to leverage existing architecture descriptions to build a comprehensive and accurate Baseline Description. Here’s a step-by-step explanation:

Existing Architecture Descriptions:

Existing architecture descriptions provide valuable insights into the current state of the enterprise’s architecture. These descriptions can include documentation of processes, systems, technologies, and organizational structures.

Baseline Description:

The Baseline Description represents the current state of the enterprise architecture. It serves as the starting point for developing the Target Architecture and planning the transition from the current state to the future state.

Using Existing Descriptions:

Review and Analyze: Existing architecture descriptions should be reviewed and analyzed to understand the current state accurately. This involves identifying all relevant artifacts, documents, and data.

Integration into Baseline: The information from the existing descriptions should be integrated into the Baseline Description. This ensures that the Baseline accurately reflects the current state, providing a solid foundation for future planning.

Gaps and Opportunities: By using existing descriptions, architects can identify gaps in the current architecture and opportunities for improvement. This helps in formulating a more effective Target Architecture.

TOGAF ADM References:

Phase A: Architecture Vision: This phase involves establishing the architecture vision, which includes defining the scope and approach for the Baseline Description.

Phase B: Business Architecture: During this phase, the Baseline Business Architecture is developed using existing architecture descriptions as a key input.

In summary, using existing architecture descriptions as the basis for the Baseline Description ensures that the current state is accurately documented, providing a reliable foundation for developing the Target Architecture and planning the transition.

The technique shown in the example is called heat mapping. It is a technique that can be used to show a range of different perspectives on a business capability map, such as maturity, effectiveness, performance, and value or cost contribution of each capability to the business2. Different attributes determine the colors of each capability on the business capability map. Heat mapping can help to identify strengths, weaknesses, opportunities, and threats in the business architecture.

In the provided diagram, item A refers to the Architecture Repository, which is a part of the TOGAF framework where all the architecture assets are stored. This includes the architectural models, patterns, architecture descriptions, and other artifacts relevant to the architecture. Item B is labeled as the Governing Board, which is likely referring to the Architecture Board or a similar governance structure responsible for oversight and decision-making regarding the enterprise architecture. Item C refers to Enterprise Capability, which encompasses the processes, tools, skills, and other capabilities that enable the architecture function within the enterprise.
