the FUNCTIONAL RESONANCE
A brief introduction to the FRAM
The understanding of the human role in accidents has gone through three stages.
The Functional Resonance Analysis Method or FRAM (Hollnagel, 2004 & 2012) provides a way to describe outcomes using the idea of resonance arising from the variability of everyday performance. To arrive at a description of functional variability and resonance, and to lead to recommendations for damping unwanted variability, a FRAM analysis consists of four steps:
