As I have said many times, we MUST examine all Latent Organizational Failures before we even begin to look at the actions of the worker(s).  Far too often, investigations will first (and usually only) look at the ACTIVE failures that led to the consequences.  This is how so many accidents IMPROPERLY and UNFAIRLY get put…...

The HFACS model was designed to be a classification tool rather than a predictive tool.

Performance Influencing Factors (PIFs) is another term, from across the pond, for error traps.  You will see me use these terms interchangeably in my HF postings, as I was formally trained to use the term PIFs, but these days it seems we use the term trap.  But after spending a year working with an organization…...
