Functional Resonance Analysis Method

Unlike traditional root-cause or failure-mode frameworks, FRAM focuses on how variability in one function can propagate through a system, a phenomenon called functional resonance. FRAM is structured around five sequential steps numbered 0 through 4. Each hexagon in a FRAM visualisation has six possible coupling types: Input, Output, Control, Resource, Precondition, and Time. FRAM is a systems-analysis tool that models complex socio-technical processes by mapping discrete activities called functions and the connections between them. FRAM is particularly suited to healthcare because roles, responsibilities, and workflows are distributed across multiple stakeholders.
