Some Ways of Improving Our Methods of Qualitative Safety Analysis and Why We Need Them

  • Jack Crawford
Conference paper


This paper follows an earlier study which questioned the validity of Probabilistic Risk Analysis. From its results it is argued that improvements are needed in the methods used for qualitative analysis. Three such improvements in method are described.
