Title: Beyond Likelihood and Consequence: Developing a Systems Approach to Risk Assessment in the Led Outdoor Activity Context


Inadequate risk assessment has often been highlighted as a contributing factor in the injuries and deaths of participants on led outdoor activity (LOA) programs in Australia, and internationally. The field of safety science considers that accidents in complex safety-critical domains (e.g. LOA’s, healthcare, aviation) are caused by a combination of decisions and actions of multiple actors situated across the system, not just by any actors working at the so-called sharp end of practice (e.g. instructor, pilot or nurse). Prior to this program of research, it was unclear as to whether this systems thinking perspective had been translated across to risk assessment practice. To address this gap, a literature review of current risk assessment methods was conducted, followed by a survey of current risk assessment practice, the subsequent development and application of a new systems thinking-based risk assessment method, and finally, testing of the method’s reliability and validity.  The studies found that current risk assessment methods and practice are not consistent with systems thinking, that existing risk assessment methods are limited in their ability to identify system wide risks, and that the new risk assessment method (the NETworked Hazard Analysis and Risk Management System; NET-HARMS) is capable of identifying systemic risks as well as emergent risks. Further, formal reliability and validity testing of NET-HARMS demonstrated that risk assessment may be enhanced by involving multiple analysts from across the work system in the process. These findings have important implications for risk assessment activities being conducted within complex safety-critical domains.
