The First Workshop was held on December 17-18, 2002 at the Zentrum fü Interdiziplinäre Forschung (ZiF) at the University of Bielefeld. There were twenty-six participants, seven talks, and two one-and-a-half hour discussion sessions. The theme of the workshop was the application and comparison of various methods of root-causal analysis. The first discussion identified a number of accidents to be analysed by various methods, and volunteers to perform the analyses by May 2003. The methods to be used and compared are SOL, WBA, STAMP and KI. The second discussion identified evaluation criteria to be used in the comparisons. A "handbook" of these criteria, their meaning and intended application, will appear here shortly.
In the first half of this talk, the support toolset ciedit and
its backend processors for easy construction of WB-Graphs is presented.
In the second half, a WB-Analysis of the accident to the Concorde aircraft
in Paris is given and results of the analysis concerning causal factors
are compared with those of the official investigation.

Two incidents using DNS in cases of domain identity spoofing are analysed using WBA. These cases are less amenable to analysis using Attack Trees or Attack Patterns because they do not constitute attacks in the usual sense. Indeed, they involve only legitimate, although arguably socially inappropriate, use of Internet facilities.Wiryana: Slides from the Talk [PDF]
The ASCE software tool from Adelard is presented and its capabilities as a "pliant system" for supporting safety case construction is demonstrated.Emmet Paper: Graphical Notations, Narratives, and Persuasion: A Pliant Systems Approach to Hypertext Tool Design [PDF]
This document, produced in real time during discussion with the ACSE tool, are mainly for the use of workshop participants. They consist mainly of a selection of cases for comparison of root-causal analysis methods along with an assignment of workshop participants who will produce case studies using the various methods; and a preliminary list of comparison criteria that will form the core of the Comparison Criteria Handbook for root-causal analysis methods.
