The know-how transmission becomes an essential condition of high technology companies continuity. In response, we propose a multimedia training platform in operators work station, called SIMPA. It was developed within the framework of a “Six Sigma” step, with a permanent concern of customers satisfaction (learners, formative persons in workshops, and managers). Its foundation is to leave a large place in the autonomous activity of the learner, by insuring him a permanent pedagogical accompaniment, thanks to two computing tutors (the professor and the companion); this answers the need of reduction in time of human tutoring. SIMPA integrates all the tools of follow-up necessary for the trainer to practise an indispensable debriefing at the end of each training session. We experimented SIMPA in situation at TED / TIV; the results are convincing, as well in credibility of our computing tutors as in diversification of pedagogical courses.
