Abstract

Risk analysis involves people with different roles and competences. The validity of the outcome depends on that they are able to communicate; ideally between themselves, but at least with or via a risk analyst. The CORAS risk modeling language has been developed to facilitate communication between stakeholders involved in the various stages of risk analysis. This article reports the results from an empirical investigation among professionals, where the purpose was to investigate how graphical effects (size, color, shape) and text labels introduced in the CORAS risk modeling language affected the understanding. The results indicate that if graphical effects are used to illustrate important information, they should also be accompanied by informative textual labels.
