Since emerging in the late 1980s, the paradigm of High Reliability Organizing (HRO) has sought to describe how and why certain organizations consistently function safely under hazardous conditions. Researchers have explored a variety of industrial situations, from the early observations of nuclear aircraft carrier operations to nursing units and even high-tech IPOs. The bulk of this research has been descriptive rather than comparative or predictive. Still, or perhaps because of this, there has been a robust and enriching academic discussion through which the paradigm has been refined and new research needs articulated. Of particular interest for the international fire community seem to be the debates concerning how 'error' is viewed, and the implications for considering how to improve safety, reliability, resilience and/or human performance. These debates appear to be on the verge of illuminating how the concepts interconnect - practically and theoretically.
