You can(’t) teach an old dog new tricks: Analyzing the learnability of manufacturing software systems in older users

Abstract

Modern manufacturing processes are based on complex computer aided planning processes, which are provided by CAM (computer-aided manufacturing)- software systems. Due to increased functional capabilities of CAM software, the complexity of these systems and the demands on CAM users are rising. Facing the demographic change (cognitively aging users, retiring of experienced CAM experts who are succeeded by inexperienced users), not only general learnability issues but also user-specific requirements are becoming increasingly important. An online-survey focusing on the learnability of CAM-software, and existing learning environments and strategies in manufacturing practice was conducted (n = 76) and effects of age and CAM expertise were analyzed. Implications for CAM skill acquisition among users of different age and expertise groups were derived.
