This paper introduces a work support and training tool (Autaki) which was developed to support automation design engineers in sharing knowledge and learning at work. The development of the application was preceded by an explorative study of automation design engineers’ work. Common problems, information needs, learning, and competence factors in the work were studied with an activity-theoretical approach called core-task analysis. The application is an interactive learning environment based on web technologies and emerging standards, such as SCORM (Sharable Content Object Reference Model). Both the core-task of automation design engineers and the application will be discussed.
