The Army helps Reserve Component training managers conduct training efficiently with visits by an Aviation Resource Management Survey (ARMS) evaluation team. This research was performed to assist the First U.S. Army Deputy Chief of Staff for Training in evaluating and revising the First Army ARMS Checklist. Aviation personnel from First Army National Guard and U.S. Army Reserve aviation support facilities and aviation units rated the Detectability, Importance, and Criticality of the checklist items, deficiencies that may result in aviation support or aviation unit failure, as applied to a unit failure, as applied to a facility and to a unit. The results indicate that, on the average, the Detectability and Importance of the items were rated moderate to high, while the Critically was rated low. The rating distributions and the verbal scale anchors suggest that different criteria may be appropriate for determining if an item is low or high on each of the three scales. A procedure for using the Detectability, Importance, and Criticality information for revising the ARMS checklist was developed. Recommendations are provided for improving the checklist content and the evaluation procedures. In addition, an ARMS Checklist data base was developed to help Army managers organize, interpret, and summarize the results of ARMS visits.
