OGBA-101 Exam Dumps - TOGAF Business Architecture Foundation Exam

In the absence of existing Architecture Descriptions, the development of a Business Architecture would begin with the gathering of relevant information about the business. This information can come from strategic documents, business plans, process documents, and stakeholder interviews, among other sources. Once gathered, this information would be used to create Business Architecture models that articulate the business vision, strategy, governance, organization, and key business processes. These models provide a blueprint that captures the essence of the business and guides subsequent architecture work.

Heat mapping is an analysis technique used in TOGAF to show a range of different perspectives on the same set of business capabilities. This technique involves visually representing data to highlight areas of importance or concern, such as performance levels, resource allocation, or risk exposure. Heat maps provide a clear and intuitive way to identify strengths, weaknesses, opportunities, and threats within the business capabilities, facilitating better decision-making and prioritization of improvement efforts.

Value networks are an approach to model, measure, and analyze business value that is primarily concerned with identifying the participants involved in creating and delivering value3. Value networks focus on the relationships and interactions among the participants, such as customers, suppliers, partners, employees, and other stakeholders3. Value networks can help to understand how value flows through the network and how it can be improved or optimized.

Value networks emphasize the interconnectedness of various entities involved in creating and delivering value. This approach goes beyond the linear view of a value chain and recognizes the complex relationships and interactions between:  

Internal participants: Different departments, teams, and individuals within the organization.

External participants: Suppliers, partners, customers, and other stakeholders outside the organization.  

By identifying and analyzing these participants, value networks help to:

Understand the ecosystem: Gain a holistic view of how value is created and delivered within a broader network of relationships.

Identify key dependencies: Recognize how different participants rely on each other and how their actions affect the overall value creation process.

Optimize collaboration: Improve coordination and collaboration between participants to enhance efficiency and value delivery.

Identify potential risks and opportunities: Assess the impact of changes or disruptions within the network on value creation

In the TOGAF ADM cycle, Phase A, the Architecture Vision phase, is where the architect would locate existing architecture descriptions to create an information map. This phase involves understanding the strategic context for the architecture work, defining the scope, identifying stakeholders, creating the Architecture Vision, and obtaining approvals to proceed with the work. Part of this involves reviewing existing documentation to understand the current state of the architecture and the information that is already available, which would be useful for creating an information map.

A business model is a description of the rationale for how an organization creates, delivers, and captures value4. Value is defined as the worth or importance of something to someone6. A business model explains what value proposition the organization offers to its customers, what revenue streams it generates from delivering the value proposition, what cost structure it incurs to create and deliver the value proposition, what key resources and activities are needed to create and deliver the value proposition, and what key partnerships are leveraged to support the value creation and delivery process4.

TOGAF defines four core architecture domains: Business, Data, Application, and Technology. These domains collectively represent the key areas covered in enterprise architecture, where the Business Architecture defines business strategy and organizational goals; Data Architecture addresses data management and structure; Application Architecture focuses on system and software applications; and Technology Architecture outlines the IT infrastructure.

References: TOGAF Standard, Architecture Domains (Chapter 3).

TOGAF, as a comprehensive Enterprise Architecture framework, divides the architecture landscape into four interrelated domains:

Business Architecture: This domain focuses on the organization's strategic goals, business processes, and organizational structure. It defines how the business operates and creates value.

Data Architecture: This domain deals with the structure, organization, and management of data assets within the enterprise. It includes logical and physical data models, data storage, and data security.

Application Architecture: This domain describes the applications used to support the business, their interactions, and their alignment with business processes. It provides a blueprint for the application portfolio.

Technology Architecture: This domain covers the technology infrastructure that supports the applications and data. It includes hardware, software, networks, and IT services.

These four domains provide a holistic view of the enterprise and how its different components work together.

Business Scenarios and Business Models are tools that architects can present to stakeholders to facilitate discussions that reveal underlying assumptions, agendas, principles, and requirements. They help in understanding the context, extracting and validating requirements, and identifying potential impacts on the target architecture. By discussing scenarios and models, stakeholders can express their vision and concerns, which may include unspoken or implicit needs that are crucial for the architecture's success.

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.

References: TOGAF Standard, Definition of an Enterprise.

TOGAF defines an Enterprise as any collection of organizations that has a common set of goals. This definition is intentionally broad and can encompass various types of entities, including:

Single organizations: A traditional company or corporation with a unified structure and goals.

Groups of organizations: This could include:

Public sector: Government agencies, military branches, or international collaborations like the United Nations.

Private sector: Consortiums, industry alliances, supply chains, or joint ventures where multiple businesses work together towards shared objectives.

The key characteristic of an enterprise is the shared set of goals that drives its activities and architecture.
