How to determine the impact of soft variables, including intangibles or social variables, and combining them as necessary with hard variables in system dynamics models is a significant challenge. This paper identifies a weakness in system dynamics modelling practice, that is, in reliably incorporating soft variables into system dynamics models. A method for(More)
System dynamics is still evolving. This paper argues additional rigour is needed if system dynamics is to achieve its full potential in helping us understand complex behaviour of human activity systems. It argues that a detailed appreciation of how systems engineers define, analyse, specify, manufacture, operate and support complex systems could inform the(More)
Research into integration of hard and soft systems methodologies for solving messy problems highlighted the need for an in-depth understanding not evident in systems thinking and system dynamics literature. The search for better insights was built around concept (cognitive) mapping of reports of Boards of Inquiry, Royal Commissions and Coronial Inquests. It(More)
