WebApr 13, 2016 · Second, FMEA is a rather qualitative analysis and does not give information on the probabilities of failure. For these reasons, fault tree analysis (FTA) is also often used (IEC 61025). In contrast to the “bottom-up” inductive approach of FMEA, the Fault Tree Analysis is a deductive method and goes “top-down”. WebFault Tree Analysis (FTA) is a deductive failure analysis which focuses on one particular undesired event and provides a method for determining causes of this event. In other words, a Fault Tree Analysis is a "top-down" system evaluation procedure in which a qualitative model for a particular undesired event is formed and then evaluated."
