Among the many domains currently exploring the use of a sociotechnical framework to help drive improvements in system performance and safety are medical systems design (e.g. Education, healthcare, entertainment and social media are among the many current, and frequently intersecting, examples of complex sociotechnical systems. While the focus of this article and special issue is on workplace safety, sociotechnical factors are at the foundation of nearly all forms of contemporary human activity. Technical factors include both the technical systems and tools that support the execution of work-related activity, as well as the technical processes and techniques used in its execution (see also Mumford 2006). demotions, terminations, etc.) that play a central role in a worker's sense of what constitutes desirable and undesirable behaviour and accomplishments on the job. rate of pay, bonuses, criteria for promotion, etc.) and punishments (e.g. Social factors also include features such as the nature of rewards (e.g.

the ‘organisational chart’) and the patterns of formal and informal command and control relationships that exist within it. These can include features such as the number and types of people employed by an organisation and/or assigned to a particular job function, the structure of the organisational elements (i.e. Social-organisational factors include system attributes related to personnel characteristics and organisational structure, policies and procedures. ( 2015), these approaches share a common theoretical framework that focuses on the interactive influences of social-organisational and technical factors (hence, the hybrid term ‘sociotechnical’) as they impact the design and performance of complex operational systems. These include areas such as cognitive systems engineering (Hollnagel and Woods 1983 Rasmussen, Pejtersen, and Goodstein 1994), macroergonomics (Hendrick 1984 Hendrick and Kleiner 2002), Leveson's system theoretic accident model and processes approach (Leveson 2012), human-systems integration 4 (Booher 2003 Tainsh 2004 Pew and Mavor 2007) and resilience engineering (Hollnagel, Woods, and Leveson 2006).Īs discussed by Carayon et al.

Although it remained a largely under-appreciated domain throughout the 1960s and 1970s, the sociotechnical ‘movement’ re-emerged in the 1980s and beyond with the advent of several important theoretical and practice-oriented approaches. The concept of the sociotechnical system originated with the insights of Tavistock Institute researchers in the early 1950s, specifically with respect to examining the impact of the introduction of novel technical systems in the British coal mining industry (e.g. This article describes the potential advantages of computer-based models and simulations for understanding factors that impact sociotechnical system design and operation, particularly with respect to process and occupational safety.Įssentially, all models are wrong, but some are useful. Practitioner Summary: The size and complexity of real-world sociotechnical systems can present significant barriers to their design, comprehension and empirical analysis. This paper describes issues involved in the design and use of such models and simulations and describes a proposed path forward to their development and implementation. From a research perspective, models and simulations afford the means to study aspects of sociotechnical system design and operation, including the potential impact of modifications to structural and dynamic system properties, in ways not feasible with traditional experimental approaches. From a design perspective, they can provide a basis for a common mental model among stakeholders, thereby facilitating accurate comprehension of factors impacting system performance and potential effects of system modifications. Computer-based models and simulations afford potentially useful means of accomplishing sociotechnical system design and analysis objectives. Empirically examining, or simply envisioning the structure and behaviour of such systems challenges traditional analytic and experimental approaches as well as our everyday cognitive capabilities. Accurate comprehension and analysis of complex sociotechnical systems is a daunting task.
