Decision Making

How to make the best choices for systems integration?

Review: Rasmussen’s 1997 paper – Risk management in a dynamic society: A modeling problem

The article by Rasmussen (1997) begins with an introduction that risk management is treated differently across all relevant hierarchical levels of a socio-technical system. However, due to the dynamics of the system, treating risk-related decision-making in isolation does not enable us to recognize when we cross the boundary of safe operation. Thus, when assessing risks in a complex socio-technical system, we have to include the layers of legislation, management, work planners and system operators. As a result, we need to touch upon risk models of the disciplines varying from economics, organizational theories and cognitive psychology to engineering.

The impact of mental models on team decisions

Mental models are a widely accepted source why decision-makers fail to make effective decisions. The concept of mental models was first introduced in the mental model theory (Johnson-Laird, 1983), defining mental models as a medium for mental representation by manipulating mental objects (making decisions) to solve a problem at hand. (Senge, 1990) makes use of the mental model concept in his research on “the learning organization”, where he defines mental models as “deeply ingrained assumptions, generalizations, or even pictures or image that influence how we understand the world and how we take action. Very often we are not consciously aware of our mental models or the effect they have on our behavior” (Senge, 1990), p.8.

Risk management in development projects, Prof. Dr. Halman – my thoughts to the lecture from a decision-making perspective

During the course Safety by Design I followed an interesting guest lecture given by prof. dr. Halman, who introduced his field of expertise: risk management in innovation projects and how to optimize decision-making in these projects. Especially, from a decision-making point of view relevant conclusions can be drawn. In the following I present my own thoughts to prof. Halman’s lecture and connect it to other literature findingsin decision-making. The lecture slides of prof. dr. Halman presentation can be found here:
