DAnGERS - Deliberative Anomaly Grading & Evaluation of Risk Significance
The Tool for Space Shuttle DAnGERS is a software tool that enables the application of Accident Precursor Analysis (APA) to Earth-to Orbit Space Transportation Systems. It utilizes qualitative grading methods to evaluate potential precursors. Integral to the APA process, the tool supports generalization of the failure mechanism observed in operation to further circumstances. Evaluation of anomalous conditions is conducted by structuring and documenting the discussion of each anomaly record, including the evidentiary basis for the findings. A combination of metrics and qualitative grading of the supporting evidence is used to assign an appropriate recommended action. The tool is designed to be operated in a deliberative discussion environment.
