Which tool is primarily used in the Phase B: Business Architecture of TOGAF?

In Phase B: Business Architecture of TOGAF, the focus is on defining the business architecture, which involves understanding the business strategy, governance, organization, and key business processes. Business Capability Modeling is a crucial tool used in this phase as it helps organizations to identify and articulate the capabilities that are necessary to achieve their strategic objectives and deliver value. By mapping out these business capabilities, organizations can see how their resources are aligned to their strategic goals, determine gaps in capabilities, and prioritize initiatives that are needed for improvement.

This approach supports the development of a clear view of what the organization does, how it delivers value, and how it can be structured for optimal performance. Business Capability Modeling provides a high-level perspective that is essential for aligning business and IT strategies.

Other tools mentioned, like Application Portfolio Management, are more relevant in the context of managing and rationalizing applications within the IT architecture rather than defining business capabilities. Similarly, while Technology Roadmaps and Data Modeling are important in other phases, they do not directly contribute to the foundational understanding of the business architecture as Business Capability Modeling does.
