The application of systematic accident analysis tools to investigate food safety incidents.

Effective food safety (FS) management relies on the understanding of the factors that contribute to FS incidents (FSIs) and the means for their mitigation and control. This review aims to explore the application of systematic accident analysis tools to both design FS management systems (FSMSs) as well as to investigate FSI to identify contributive and causative factors associated with FSI and the means for their elimination or control. The study has compared and contrasted the diverse characteristics of linear, epidemiological, and systematic accident analysis tools and hazard analysis critical control point (HACCP) and the types and depth of qualitative and quantitative analysis they promote. Systematic accident analysis tools, such as the Accident Map Model, the Functional Resonance Accident Model, or the Systems Theoretical Accident Model and Processes, are flexible systematic approaches to analyzing FSI within a socio-technical food system which is complex and continually evolving. They can be applied at organizational, supply chain, or wider food system levels. As with the application of HACCP principles, the process is time-consuming and requires skilled users to achieve the level of systematic analysis required to ensure effective validation and verification of FSMS and revalidation and reverification following an FSI. Effective revalidation and reverification are essential to prevent recurrent FSI and to inform new practices and processes for emergent FS concerns and the means for their control.

Forgotten children: a socio-technical systems analysis of the 2004 and 2015 forced child labour reports from Indian cottonseed farms.

Using a systems analysis approach, the authors analyse forced child labour incidents in Indian cottonseed farms in the years 2003/04 and 2014/15, and explore the role played by human factors in contributing to the illegal use of child labour in the Indian agri-food sector. National policies on labour welfare and rights are reviewed through the case studies used as a lens to explore wider issues associated with forced child labour in supply chains. The study highlights the evolution of organised crime in India with regards to the reliance on forced child labour, using the four conceptual dimensions of modern slavery established by the UK Home Office in 2017. The study does identify limitations and flaws associated with designing policies based on a "work-as-imagined" philosophy and demonstrates how the use of maturity modelling can explore how exploitation, corruption and organised crime is framed and can become more formalised over time.

Human factors and ergonomics systems-based tools for understanding and addressing global problems of the twenty-first century.

Sustainability is a systems problem with humans as integral elements of the system. However, sustainability problems usually have a broader scope than socio-technical systems and therefore, require additional considerations. This requires a fuller integration of complex systems understanding into the systems analysis toolset currently available to human factors and ergonomics. In this paper, we outline these complex systems requirements necessary to tackle global problems such as sustainability and then assess how three common systems analysis tools (i.e. Accimap, System Theoretic Accident Mapping and Processes, and Cognitive Work Analysis) stand up against these revised criteria. This assessment is then further explored through applying two of these tools (i.e. Accimap and System Theoretic Accident Mapping and Processes) to a transnational food integrity system problem. This case study shows that no single systems analysis method can be used in isolation to help identify key insights for intervention and that new methods may need to be developed or existing methods need to be adapted to understand these dynamic, adaptive systems. The implications for the further development of systems analysis tools are discussed. Practitioner summary: We assess the applicability of existing human factors and ergonomics systems-analysis tools for examining global problems and for identifying points to intervene in these systems. We comment on what extensions and further work will be required to enable human factors and ergonomics to intervene effectively.
