In complex domains, maintenance personnel may be required to use multiple software tools for receiving status information and controlling resources across the enterprise. These tools have evolved to be effective for collecting status, but often lack integrated contextual information for personnel to understand failure event impact to the enterprise and operational mission. Through a human-centered design approach, salient concepts and semantically relevant maintenance information can be captured within a domain. This research will show that an ontology can be a useful method to establish a common frame of reference to promote better situation awareness and more effective decision-making and collaboration among stakeholders in regards to maintenance information. Consequently it will promote availability, a more robust safety culture, and reduced costs. The Federal Aviation Administration (FAA) will be used as a case study.
