OGBA-101 Exam Dumps - The Open Group TOGAF Business Architecture Foundation Questions and Answers

The diagram provided illustrates a Capability Map. Here's why:

Focus on "what" the organization does: The diagram depicts various functions and activities that the organization performs, such as "Program/Human Resource Matching," "Employee Supply and Demand Mgmt," "Benefits Management," etc. These represent the capabilities of the organization, or what it is able to do.

Hierarchical structure: The capabilities are organized hierarchically, with broader functions like "HR Mgmt." encompassing more specific capabilities like "Position Advertising" and "Skills Assessment." This shows how different capabilities relate to each other and contribute to higher-level functions.

No specific process flow: Unlike a process map or value stream map, this diagram doesn't show a sequence of steps or flow of activities. It focuses on the capabilities themselves, not how they are executed

TOGAF defines an “Enterprise” as any collection of organizations or alliances working toward shared goals, such as in consortiums or partnerships. This scope allows the architecture to address cross-organization processes and infrastructures for collaborative endeavors.

According to the TOGAF Standard, business scenarios are an important technique that may be used at various stages of the enterprise architecture, principally the Architecture Vision and the Business Architecture, but in other architecture domains as well, if required, to derive the characteristics of the architecture directly from the high-level requirements of the business1. The Architecture Vision is developed in Phase A, and the Business Architecture is developed in Phase B. The Preliminary Phase is also a stage where business scenarios can be used to help identify and understand business needs2.

Business scenarios are a tool used within TOGAF to help identify and understand the business requirements and to drive the creation of the enterprise's architecture. They are used in the Preliminary Phase to understand the organizational context, Phase A to develop the Architecture Vision, and Phase B to derive the Business Architecture based on the stakeholder's requirements and the business strategy.

According to the TOGAF Series Guide: Organization Mapping, one of the derived relationships in an organization map is value flow1. A value flow is a relationship that shows how value is exchanged between business units or other entities in an organization map1. A value flow can be expressed as a verb phrase that indicates what type of value is transferred or shared between entities1. For example, in an organization map for an online retailer, a possible value flow could be “Delivers products” between the Warehouse business unit and the Customer entity.

In a business scenario, business capabilities and value streams are modeled when identifying the business and technology environment. Here’s a detailed explanation:

Business Scenarios in TOGAF:

Business scenarios are used to capture and describe the business requirements, providing a context for the architecture development. They help in understanding the business environment, identifying problems, and defining desired outcomes.

Identifying the Business and Technology Environment:

Business Capabilities: During this phase, the architect identifies the key business capabilities required to achieve the business objectives. These capabilities represent what the organization needs to be able to do.

Value Streams: Value streams are also identified and modeled to understand how value is delivered to customers and stakeholders. They provide a high-level view of the end-to-end processes that create value.

TOGAF ADM References:

Phase A: Architecture Vision: In this phase, understanding the business and technology environment is crucial for defining the architecture vision. Modeling business capabilities and value streams provides a foundation for this understanding.

Phase B: Business Architecture: This phase involves a detailed analysis of business capabilities and value streams to ensure that the architecture supports the business strategy and objectives.

Importance:

Contextual Understanding: By modeling business capabilities and value streams, architects gain a comprehensive understanding of the business and technology environment. This helps in aligning the architecture with business needs and ensuring that it supports value creation.

Strategic Alignment: Identifying and modeling these elements ensures that the architecture is aligned with the strategic goals of the organization and supports its key business activities.

In summary, business capabilities and value streams are modeled when identifying the business and technology environment, providing a comprehensive understanding of how the organization operates and how the architecture can support its objectives.

According to the TOGAF Series Guide to Value Streams (Version 1), a value stream stage is defined as “a distinct part of a value stream that represents a group of activities contributing to an overall result” 5. A value stream stage can be expressed as a noun phrase that indicates what outcome or state is achieved by completing the stage5. For example, some possible value stream stages are “Product Ordered”, “Payment Processed”, or “Customer Satisfied”. The example value stream shows how an online retailer creates and delivers value for its customers by performing five value stream stages: “Acquire Retail Product”, “Advertise Channels”, “Display Products”, “Enable Selection”, “Process Payment”, and “Deliver Product(s)” 5. Therefore, the value stream is decomposed into five value stream stages.

Business model innovation involves making significant changes to how an organization creates, delivers, and captures value. These changes can be disruptive and have far-reaching implications for the entire enterprise. A structured approach to business model innovation is essential to:

Maintain alignment with enterprise architecture: A structured approach ensures that new business models are compatible with the existing technology, data, and application architecture. This prevents costly rework, integration issues, and disruptions to existing operations.

Minimize risk and disruption: By carefully considering the impact of changes on different parts of the organization, a structured approach helps to mitigate risks and avoid unintended consequences.

Facilitate effective decision-making: A structured approach provides a framework for evaluating different business model options and making informed decisions based on clear criteria and analysis.

Enable smooth transition: A structured approach helps to manage the transition to the new business model, ensuring a smooth implementation and minimizing disruptions to customers and employees.

Risk is defined as the effect of uncertainty on objectives. It can be positive or negative depending on whether it enhances or hinders the achievement of objectives. Threat is a potential cause of risk that could have a negative impact on objectives. Continuity is the ability to maintain or resume normal operations after a disruption or disaster. Vulnerability is a weakness or exposure that could be exploited by a threat to cause harm or damage.

In TOGAF, the dimensions for scoping an architecture are Breadth (coverage across the organization), Depth (level of detail), Time Period (horizon of the architecture), and Architecture Domains (the four architecture domains of Business, Data, Application, and Technology). These dimensions ensure comprehensive scoping and contextual alignment.
