Abstract: An engine diagnostic system in accordance with an embodiment not only captures the written feedback from each technician, but also tracks every step/click that the technician took during the diagnostic process and classifies those clicks into desirable or undesirable behavior patterns that indicate missing or miss-tagged content, inefficiently presented materials, or training issues such as not following troubleshooting guidance. The system provides daily updates of troubleshooting status's of diagnoses being conducted on millions of engine systems that represent a great amount of different engine models and types from around the globe, and provides data reduction techniques and metrics that guides the analyst/service engineers to high priority emerging issues reduced to specific actionable events that can be corrected and immediately monitored for their impacts on the troubleshooting system efficiency measures.
