The Open Group Certification OGBA-101 Release Date

The example value stream shown, labeled "Acquire Retail Product," represents a decomposition into a sequence of stages that collectively create value. Each stage, such as "Advertise Channels," "Display Products," "Enable Selection," "Process Payment," and "Deliver Product(s)," is a step in the overall process that contributes to the final outcome, which in this case is the acquisition of a retail product by the customer. Value streams are utilized in business architecture to model the flow of value through an organization from the initial customer demand to the final delivery of the product or service.

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.

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

TOGAF's ADM (Architecture Development Method) is designed to be iterative at multiple levels: over the whole process, between phases, and within phases. This iterative approach allows for continuous refinement and improvement of the architecture, ensuring it remains aligned with changing business needs and technological advancements. Iteration helps in managing complexity and facilitates incremental development, enabling architects to revisit and adjust their work as new information and insights emerge.
