In this paper, we identify user requirements for Remote Maintenance Monitoring (RMM) and identify high-level RMM tasks based on the Cognitive Task Analysis results. RMM is a primary means of maintaining the National Airspace System. Technical Operations Specialists have specific information that they need to see to do their jobs effectively and efficiently when using RRM systems. Thus, Technical Operations Specialists requested an evaluation of information requirements for RMM systems. Human Factors Researchers collected data from Technical Operations Specialists at four facilities. Twelve participants performed think-aloud exercises and cognitive walk-through exercises, and 28 participants completed a survey. The resulting data led to a Cognitive Task Analysis list of tasks and 29 recommendations regarding information requirements, including ways to better tailor the amount and form of presented information to better meet the needs of the user and the organization. For RMM to be an effective tool for performing maintenance, the RMM system must have an effective user interface. When asked what they would change about the RMM system, specialists responded (a) that they would like RMM to be quicker (i.e., closer to real time), (b) that they would like to have default settings that would let each user pick which sites and units to monitor, and (c) that they would like to remove or reduce the number of false alarms that occur.
