Abstract
In complex sociotechnical systems, cognitive and social humans use technology to make sense of situations when making decisions. These elements make sociotechnical systems difficult to develop. A modelling and assessment methodology for systems engineering is required to understand the sociotechnical system’s behaviour and underlying structure. Modelling captures the dynamic interaction, as well as the effect of humans in a complex environment. Cognitive Work Analysis and System Dynamics are two complementary approaches applied in mutual support within this context. The objective of this paper is to demonstrate a modelling methodology for complex sociotechnical systems, in order to support the systems engineering process.
Highlights
The development of complex sociotechnical systems (STS) often consists of integrating new technology into existing systems through the application of systems engineering (SE) processes
This paper addresses the final stages of the design science research (DSR) framework, which is to evaluate the ability of the modelling methodology to model the impact of a new technology in a complex STS
The outputs of the modelling and simulation are compared with the findings of an empirical case study in order to demonstrate the utility of the modelling methodology in supporting learning about a complex STS that supports an SE approach
Summary
The development of complex sociotechnical systems (STS) often consists of integrating new technology into existing systems through the application of systems engineering (SE) processes. Suitable technology is required to capture and distribute information on incidents and suspicious behaviour reported by the patrollers [33,34] This can be viewed as a complex STS because it consists of humans interacting with each other in small diverse teams using processes, structure, and technology. This was done as an initial exploratory evaluation of the artefact and SD models [30,31].The aim of the case study is to evaluate the ability of the modelling methodology to support an understanding of the effect of a new technology on a complex STS This was achieved by implementing a new technology in an existing CPF (located in Pretoria, South Africa) to determine whether the developed models provided insight into the observed behaviour. The models, constructs, and simulations developed through the modelling process identified the characteristics to be addressed in the interviews
