A solid business capability model is fundamental to enterprise architecture in SAP LeanIX because it serves as the primary bridge between business strategy and IT execution. It provides a stable, high-level view of what the business does, creating a common language that both business and IT stakeholders can understand (A). This shared understanding is crucial for collaboration. By mapping applications, projects, and technologies to these business capabilities, enterprise architects can ensure that all IT investments and activities are directly justified by and aligned with specific business needs and strategic objectives, preventing technology-driven silos (D).

B. A business capability model describes what a business does, not the underlying technology. Identifying hardware dependencies is a function of mapping the application and technology layers of the architecture.

C. This confuses capabilities with processes. A capability is what a company can do (e.g., "Invoice Management"), while a process describes how it is done. Capability models are abstractions, not detailed process flows.

1. SAP LeanIX Documentation

"Business Capability Maps: The Rosetta Stone for Business and IT": This official guide states

"Business capabilities are the single most important element for linking IT to the business. They describe what a business is doing..." It emphasizes that capabilities create a "common language" (supporting A) and are used to "align IT with business goals" (supporting D). (Accessed via SAP LeanIX Product Documentation portal).

2. SAP LeanIX Whitepaper

"The Ultimate Guide to Business Capability Modeling": Section "Why are Business Capabilities so important?" explains that they "provide a common language for business and IT" and "are the key to aligning IT with business goals." This directly validates answers A and D. The paper also clarifies

"Business capabilities are not business processes

" which invalidates option C.

3. The Open Group

"TOGAF® Standard

10th Edition

" Part II: Architecture Development Method (ADM)

Phase B: Business Architecture: Section 6.3.3

"Business Capabilities

" describes capabilities as a view of the business that is "stable in the face of organizational and process change." It highlights their role in "articulating the business strategy" and linking it to other architectural domains

which is the essence of alignment (supporting D).
