A systems analysis of the Air Force On-the-Job-Training (OJT) System was conducted to describe its operation, structure, requirements, and functions, and to develop new or improved methods and alternatives for evaluating the effectiveness of OJT programs. Seven major command headquarters locations were visited for the purpose of discussing possible ways of improving the system with OJT staffs and to discuss plans to make site visits to field-activity locations. The staffs were asked to comment on plans for field activity questionnaires and to evaluate preliminary ideas for improving OJT programs. A number of base-level field-activity locations were then visited. An analysis was made of OJT policies and procedures at each location. Ways of improving the OJT program were discussed with OJT administrators and work-center superintendents. Questionnaires were criticized and refined by small groups of work-center superintendents, OJT administrators, and trainees. On later site visits, some data was gathered using these questionnaires. Seventeen problem areas were identified during the visits and conferences. The nature of each problem area was defined, in part, by reactions of work-center superintendents and OJT administrators to specific suggestions for improving the Air Force OJT program. Three complete revisions were made and 75 recommendations were under consideration when the field-activity visits ended. Additional information about problem areas was obtained by analyzing survey data collected by the Air Force OJT Advisory Service in their 1973 survey of 1,592 OJT supervisors and 1,580 trainees. Thirty tentative conclusions were drawn. Specific recommendations for program changes were made, including recommendations for field tests and surveys to validate those conclusions that require additional information prior to wide-scale implementation. The specific conclusions and related recommendations, along with individual priority ratings, are included in the report. (LAS)
