Aggregering av riskbedömningar i den nationella riskhanteringsprocessen – Användning av centrala myndigheters risk- och sårbarhetsanalyser som underlag för nationell riskbedömning

A study was performed to investigate whether the risk- and vulnerability assessments of Swedish central authorities fulfill its purposes stated in the legislation. This was made by investigating and categorizing the characteristic ways the authorities communicate risks in their RVA:s. A content analysis of ten risk- and vulnerability assessments was performed as well as a participating observation at a workshop, where central authorities were developing consequences for their respective sectors in a given scenario. It is concluded from the results that the RVA:s alone cannot be considered to fulfill the purposes stated in the legislation, but depend on consequent workshops to fulfill the purposes. This is mainly due to poor representation of uncertainties and background knowledge that forms the basis of estimates and judgments
