ABSTRACT
Risk assessment is anticipatory in nature and supports feed-forward processes rather than the feedback processes of, for example, accident investigations. Risk management means the total coordinated activities that take place to direct and control an organisation with regard to risk (ISO 2009). Thus, it includes risk assessment and risk treatment together with communication of information about risk as well as systematic monitoring and review of processes. Tacit knowledge plays an important role in all parts of risk assessment, and utilisation of this knowledge is accomplished by the risk assessment team serving as an arena of experience exchange. Individuals with operational experience from situations similar to those of the analysis object share tacit knowledge about hazards, causes, expected frequencies, and so on. This shared knowledge is converted into concepts suitable for the context of the risk assessment through group discussions and is documented in the risk assessment.
