SAP LeanIX uses a standard Application Portfolio Management (APM) methodology to assess the health and value of applications. The two primary, default attributes for this assessment are Functional Fit and Technical Fit. Functional Fit evaluates how well an application supports business capabilities and user needs. Technical Fit assesses the quality of the underlying technology, considering aspects like maintainability, scalability, and alignment with architectural standards. Together, these two dimensions form the basis for the TIME (Tolerate, Invest, Migrate, Eliminate) model, a core feature for strategic application portfolio decisions within SAP LeanIX.

A. Operational fit: While a relevant concept, "Operational Fit" is not a standard, default assessment attribute in SAP LeanIX; its aspects are typically covered under Functional Fit or Business Criticality.

D. IT health score: This is typically a calculated or aggregated metric derived from other primary attributes like Functional and Technical Fit, not a default input attribute itself.

the core assessment methodology is described. It states

"The assessment is based on two dimensions: Functional Fit and Technical Fit. These dimensions are used to categorize applications in the Application Portfolio matrix..."

3. University Courseware on Enterprise Architecture: Enterprise Architecture frameworks taught in academic settings often use a two-dimensional matrix for portfolio analysis. The most common axes are business value (or functional fit) and technical condition (or technical fit)

which aligns directly with the SAP LeanIX default model.
