The Open Group OGBA-101 Practice Test Questions Answers

In developing an Architecture Vision within TOGAF, the architect should examine and search for foundational Business Architecture concepts to ensure that the enterprise architecture is aligned with the organization’s strategy and delivers value to stakeholders. Here’s a detailed breakdown of the relevant Business Architecture concepts that need to be examined in this context:

Business CapabilitiesBusiness Capabilities represent the core abilities or capacities of an organization that allow it to achieve specific purposes or outcomes. In TOGAF, identifying and analyzing Business Capabilities helps architects understand the organization’s functional strengths and gaps. This examination provides insight into which capabilities are critical for achieving strategic goals and how they may need to evolve to support the target architecture.

Value StreamsValue Streams depict the end-to-end processes that deliver value to customers, stakeholders, or end users. By identifying Value Streams, the architect can understand how value is created and delivered, ensuring that architecture decisions support these value-generating processes. Value Streams in TOGAF are integral to identifying areas where improvements, efficiencies, or innovations can be applied, enhancing the organization’s ability to meet its strategic objectives.

Organization MapsOrganization Maps outline the relationships between various entities within the enterprise, including internal departments, partners, and stakeholders. These maps provide a structural overview, showing the formal and informal relationships that influence how work is conducted across the organization. In the Architecture Vision phase, Organization Maps help architects understand organizational dependencies, stakeholder concerns, and potential alignment issues between business units.

Application in the Architecture Vision Phase:By examining these concepts—Business Capabilities, Value Streams, and Organization Maps—the architect can gain a comprehensive understanding of the current state of the business and how it is structured to deliver value. This analysis is essential for setting a realistic and strategically aligned vision that addresses core business needs and prepares the organization for future growth and transformation.

TOGAF Business Architecture guidelines on Business Capabilities, Value Streams, and Organization Mapping

The development of Business Architecture Descriptions is always iterative because it involves constant refinement and validation of the architecture models and views based on stakeholder feedback and changing requirements. Therefore, any Architecture Description that was created in Phase A may need to be updated in Phase B as new information or insights emerge. Phase B does not require that all Architecture Descriptions be updated, only those that are relevant and necessary for the Business Architecture. Phase B is an ADM Architecture Development phase, but that does not explain why Architecture Descriptions need to be updated. A new value stream may or may not require updating existing Architecture Descriptions depending on its scope and impact.

In TOGAF's ADM, the development of architecture is an iterative process. During Phase A, initial business capability maps and value streams are created to establish the Architecture Vision. However, as stakeholders provide more detailed inputs and requirements are refined, it is necessary to update the Architecture Descriptions. This is an iterative process that continues into Phase B, Business Architecture, where these descriptions are further developed and refined.

Value Stream Mapping (VSM) is a powerful tool used to assess an organization's effectiveness at creating, capturing, and delivering value for different stakeholders. It involves mapping out the entire process of value creation from end to end, identifying each step involved, and analyzing how value is added at each stage. VSM helps in identifying bottlenecks, inefficiencies, and opportunities for improvement, ultimately aiming to optimize the value delivery process to better meet stakeholder needs.

A business capability map is a comprehensive representation that showcases an organization's abilities in a structured manner. It identifies and illustrates the various business capabilities that allow the enterprise to function and deliver value. These capabilities are often defined independently of the organizational structure, processes, or technology, focusing instead on what the business does and can do. This map encompasses the end-to-end value delivery and how different capabilities interrelate and support one another, thus providing a holistic view of the business's functional abilities.

 The technique shown in the example is called relationship mapping. It is a technique that can be used to show how a business architecture addresses stakeholder concerns across different parts of an organization2. It can highlight gaps or overlaps in the coverage of stakeholder concerns by a business architecture. In this case, the technique is used to relate business capabilities to organization units so as to highlight duplication and redundancy.

This modeling technique is referred to as Relationship Mapping. It's used to relate business capabilities to organizational units to highlight areas of duplication and redundancy, as well as to indicate where capabilities are being performed well (green), where there are potential issues (yellow), and where there are significant problems or gaps (red). This visualization helps in understanding the alignment between organizational units and capabilities, and where improvements or changes may be needed.
