The Open Group OGBA-101 - TOGAF Business Architecture Foundation Exam

The TOGAF standard covers the development of four architecture domains: Business, Data, Technology, and Application. The Application Architecture domain defines the applications required to process the data and support the business functions.

The TOGAF standard describes the development of four architecture domains, which are considered its pillars. These are Business, Data, Technology, and Application. The Application Architecture domain provides a blueprint for the individual application systems to be deployed, their interactions, and their relationships to the core business processes of the organization.

According to the TOGAF Standard, an enterprise is defined as any collection of organizations that has a common set of goals and/or a single bottom line1. The examples given in the question are all types of enterprises that can be the subject of enterprise architecture1.

In the context of TOGAF, the term 'enterprise' encompasses more than just a single organization. It refers to any collection of organizations that has a common set of goals. This can include, as described in the statements provided, entire corporations or their divisions, government agencies or departments, as well as business partnerships such as consortia or supply chains. TOGAF uses the term 'enterprise' to define the full scope of the entity that is the subject of planning, design, implementation, and operation of an Enterprise Architecture.

Information mapping in TOGAF is a technique used to represent business information assets that are either currently in use or planned for future use by the enterprise. Here’s a detailed explanation:

Purpose of Information Mapping:

Information mapping provides a clear visualization of how information flows within the enterprise, highlighting the information assets and their interactions. This is crucial for understanding the current state and planning the future state of information management.

TOGAF Framework:

Phase C: Information Systems Architectures: Within this phase, information mapping is used to develop the Data Architecture, which outlines the structure of an organization's logical and physical data assets and data management resources.

Supporting Analysis: Information mapping supports various analyses, including gap analysis, impact analysis, and the identification of information dependencies and redundancies.

Benefits:

Clear Representation: It provides a clear and structured representation of business information assets, aiding in the understanding and management of information flows.

Alignment with Business Processes: Helps ensure that information assets are aligned with business processes and objectives, enhancing the efficiency and effectiveness of information usage.

Components:

Current Information Assets: Information mapping identifies and catalogs the information assets currently in use within the enterprise.

Planned Information Assets: It also includes planned information assets that will be needed to support future business processes and strategies.

In summary, information mapping is a technique to represent business information assets in use or planned by the enterprise, providing a structured view of information flows and supporting effective information management.

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.

Business models are essential tools within TOGAF for providing different perspectives on the business operations, strategies, and value propositions. Here’s a detailed explanation:

Purpose of Business Models:

Business models are designed to represent various aspects of the business, such as value creation, delivery, and capture mechanisms. They provide a structured way to analyze and understand the business.

Different Viewpoint:

Cross-Check Assumptions: Business models offer a different viewpoint that helps in validating and cross-checking assumptions made about the business. By presenting a visual and structured representation of the business, these models enable stakeholders to identify gaps, inconsistencies, and areas that need further analysis.

Holistic Understanding: They help in gaining a holistic understanding of how different components of the business interact, which is crucial for ensuring that the enterprise architecture aligns with the business strategy and goals.

TOGAF References:

Phase A: Architecture Vision: During this phase, business models are used to articulate the vision and scope of the architecture effort. They help in ensuring that all assumptions are validated and that the architecture aligns with business objectives.

Phase B: Business Architecture: Business models are also utilized in this phase to analyze business capabilities, processes, and value streams. They provide a different viewpoint that aids in identifying areas for improvement and ensuring alignment with the strategic intent.

In summary, business models provide a different viewpoint that helps cross-check assumptions, ensuring that the enterprise architecture is aligned with the business strategy and objectives.

The chart depicted is a Gantt chart, which typically represents the schedule for project activities. In the context of TOGAF's ADM, it is used to illustrate the sequence and interdependencies of tasks across different phases of architecture development. The ADM is an iterative cycle that includes various phases, from the preliminary phase, through architecture vision, business, information systems, and technology architectures, to opportunities and solutions, migration planning, implementation governance, and architecture change management. Each phase must be conducted in a sequence to ensure that the outputs of one phase feed into the next, thereby producing a coherent and structured architecture.

Business capabilities in TOGAF are defined as the ability of an organization to achieve a specific purpose or outcome. The components that make up a business capability typically include:

Roles: The responsibilities and positions within the organization that support the capability.

Processes: The activities and workflows that are essential to the functioning of the capability.

Information: The data and knowledge necessary for the capability to operate effectively.

Resources: The assets, such as people, technology, and materials, required to support the capability.

This comprehensive definition ensures that each capability is fully understood in terms of the resources and activities required to deliver its intended outcomes.

Architecture Principles in TOGAF govern the architecture process, influencing the development, maintenance, and use of the Enterprise Architecture. Here's a detailed explanation:

Definition:

Architecture Principles: These are the fundamental rules and guidelines that inform and support the way in which an organization sets about fulfilling its mission. They affect all phases of the architecture process.

Role in TOGAF:

Guidance and Governance: Architecture Principles provide the foundation for making architecture-related decisions. They guide the development, maintenance, and usage of all architecture artifacts.

Consistency and Alignment: They ensure that all architecture activities are consistent with the overall business strategy and objectives, providing alignment across different architecture domains.

TOGAF ADM Phases:

Preliminary Phase: This phase includes the establishment of architecture principles that will guide the entire architecture effort.

Phase A: Architecture Vision: During this phase, the architecture principles are used to create the vision and scope of the architecture project, ensuring it aligns with the organization's goals.

Examples of Architecture Principles:

Business Principles: These might include ensuring that business processes are customer-focused.

Data Principles: Principles ensuring data accuracy and availability.

Application Principles: Guidelines for application interoperability and usability.

Technology Principles: Standards for technology choices and infrastructure management.

In summary, architecture principles govern the architecture process, affecting its development, maintenance, and use, thereby ensuring alignment with business goals and consistency in architectural decisions.

According to the TOGAF Business Capabilities Guide V2, a business capability is defined as "the expression or the articulation of the capacity, materials, and expertise an organization needs in order to perform core functions"5. A business capability can be decomposed into four elements: roles, information, processes, and technology5. In the given example, A represents roles and C represents information.

In the context provided in the image, 'A' refers to the roles involved in the recruitment management process, which in this case is the 'User: Recruiter' and the 'Stakeholders: Manager, Candidate Employee'. 'C' refers to the information or data aspects of the process, which includes 'Candidate/Applicant Details', 'Position Descriptions', 'Recruitment Agency Data', and 'Industry Standard Role Definitions'. Thus, 'A' corresponds to 'Roles' and 'C' to 'Information'.

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.
