SAP LeanIX is an Enterprise Architecture Management (EAM) solution designed to provide a comprehensive overview of an organization's IT landscape. Its central use cases are rooted in managing and transforming this landscape. Application Portfolio Management (APM) is a core function, enabling organizations to inventory, assess, and rationalize their software applications to reduce complexity and cost. Equally central is Technology Risk and Compliance, which involves identifying and mitigating risks associated with obsolete technology, managing software lifecycles, and ensuring adherence to standards, thereby enhancing security and compliance.

A. Spend Management: While effective APM and risk management lead to optimized IT spending, Spend Management itself is a broader financial discipline and a result of using LeanIX, not a central use case.

B. Blockchain Analytics: This is a highly specialized data analysis field. SAP LeanIX is a strategic EAM tool and does not offer deep analytical capabilities for specific technologies like blockchain.
