Event Tree Analysis
Event tree analysis (ETA) is a low-level tool that is useful for describing failure sequences. You can use ETA to provide more detail on failure modes or effects for FMEA analysis. ETA occasionally reveals new failure modes within a system.
The ETA develops a model of outcome events based on an initiating event. Many events can be modeled, including automatic system responses and human responses. ETA effectively accounts for the timing, dependence, and domino effects among various contributors that are cumbersome to model in fault trees.
