The General Process of Applying STAMP to Accident Analysis

1 The General Process of Applying STAMP to Accident Analysis 

In STAMP, an accident is regarded as involving a complex process, not just individual events. Accident analysis in CAST then entails understanding the dynamic process that led to the loss. That accident process is documented by showing the sociotechnical safety control structure for the system involved and the safety constraints that were violated at each level of this control structure and why. The analysis results in multiple views of the accident, depending on the perspective and level from which the loss is being viewed. 

Although the process is described in terms of steps or parts, no implication is being made that the analysis process is linear or that one step must be completed before the next one is started. The first three steps are the same ones that form the basis of all the STAMP-based techniques described so far. 

Identify the system safety constraints and system requirements associated with that hazard. 

Document the safety control structure in place to control the hazard and enforce the safety constraints. This structure includes the roles and responsi-
