Abstract
The present invention discloses a system and method to evaluate intrusive repair. The method and system is based on analyzing data from the field and drawing causal diagrams (cause-consequence diagrams). In an aspect of the present invention, a method and system for evaluating intrusive repair for a class of devices comprises providing a threshold time window for analyzing failure data. The system and method further includes utilizing a causal diagram based on the analysis of the failure data for the class of devices to indicate the probability of intrusive repair. In the present invention, two measures are defined to evaluate intrusive repair--intrusivability and one-fixability. Intrusivability is defined as the probability that a repair action will cause a new fault. One-fixability is defined as the probability that the diagnostic process will fix the fault on the first repair attempt. Both of these measures are determined by using the causal diagram in accordance with the present invention.
