Conducted as part of a major effort to test and evaluate Job Performance Aids (JPA) and their integration with Navy personnel and training systems, this study systematically reviewed and organized existing JPA techniques, related research data, and various applicable principles and concepts. One hundred and one JPA systems and techniques were classified under the following five categories: (1) format/content, (2) display media, (3) applied training, (4) peripheral test/diagnostic, and (5) delivery systems. The following factors were identified as critical to the development of a JPA algorithm: personnel aptitude and experience; type and complexity of task; type and complexity of equipment; and the degree of proceduralization required. A conceptual model was developed for use by the JPA community in making cost trade-off analyses, writing JPA selection algorithms, and grouping theoretical trends. The study also examined a theoretical base for the use of memory in JPA's; previewed a theory for mixing JPA techniques, principles, and methodologies; and set goals for future JPA research and technology efforts.
