Use when reasoning about how a system, user, or designer's internal model of behavior may diverge from reality — applies across UX, distributed systems, type systems, API design, and team collaboration. Covers the three-model frame (designer / system image / user), the two gulfs (execution and evaluation), analogy and metaphor as model-seeding, the five failure modes (transfer, overgeneralization, underspecification, drift, invariant blindness), the surface/operational/architectural/domain layering, and the discipline of validating a model against the system it claims to represent. Do NOT use for the visual representation of a model (use knowledge-modeling), for the formal-domain entities-attributes-relationships of conceptual modeling (use conceptual-modeling), for cognitive biases in decision-making (out of scope), or for empirically eliciting user models via research methods (use user-research).
