What went right? An analysis of the protective factors in aviation near misses

Abstract

Learning from successful safety outcomes, or what went right, is an important emerging component of maintaining safe systems. Accordingly, there are increasing calls to study normal performance in near misses as a part of safety management activities. Despite this, there is limited guidance on how to accomplish this in practice. This article presents a study in which using Rasmussen's risk management framework to analyse 16 serious incidents from the aviation domain. The findings show that a network of protective factors prevents accidents with factors identified across the sociotechnical system. These protective networks share many properties with those identified in accidents. The article demonstrates that is possible to identify these networks of protective factors from incident investigation reports. The theoretical implications of these results and future research opportunities are discussed. Practitioner Statement: The analysis of near misses is an important part of safety management activities. This article demonstrates that Rasmussen?s risk management framework can be used to identify networks of protective factors which prevent accidents. Safety practitioners can use the framework described to discover and support the system-wide networks of protective factors.

Suffering, Systems, and Safety: Applying the Principles of Systems Safety to Improve the Care of Patients With Cancer

“…A recent analysis of 12 aviation reports of near misses found that accidents were averted in each case because of effective vertical integration. 16 "Contrary to the common belief that a single act can save the day," the authors found that "communication (both within and across levels) and feedback and control loops develop a network of protective factors which can lead to accident prevention." 16(p199) Errors are not interrupted only by "heroic moments of inspired action" 16(p199) ; they are interrupted when protective factors interact to steer the system toward safety.…”

“…Instead of looking for causative or contributory factors after a failure, preemptive risk reduction looks for factors that are protective to better understand how things go right. 16 It is Three competing boundaries influence the state of safety in any complex system. The black "X" identifies a system in which risk is contained, one in which the competing boundaries are in balance.…”

Human Factors Quality Control in Air Traffic

“…The extent of the effect on a person and his colleagues is pervasive and versatile. Then again, some people essentially explore comfort and relief in the workplace if situational stress is an outcome of factors outside of their employment [9,40].…”

The relationship between the dynamic model of crew resource management and line operational safety audits

“…Within the CRM-DYMO model it is specifically concerned with the transmission of data/information. Effective communication has been identified as a protective factor for the safe and efficient conduct of a flight (Thoroman et al, 2019). Good teamworking also promotes situation awareness and hence decision making (see Kanki, 2010).…”
