Many companies using Statistical Process Control (SPC) in their manufacturing processes have found that, despite the training difficulties presented by the technique, the rewards of successful SPC include increased productivity, quality, and market leadership. The Ford Motor Company has developed its SPC training with interactive video, which provides a variety of message systems via a single medium, including moving pictures, static pictures, text, diagrams, and sound, all with the opportunity for interaction. Experiments with interactive video training in the United States and the United Kingdom have confirmed its effectiveness and that trainees enjoy using it. Ford commissioned the development of an interactive video course on SPC and recommended its use to its supplier companies for training its personnel, from middle management to shop floor operators. In this video, live drama with question and answer sequences is complemented with graphic animation and interactive simulations. Ford commissioned the Council for Educational Skills Training to investigate the effectiveness of and user response to the first two disks. Most of the participants' responses to a questionnaire and follow-up interview indicated strong positive feelings about the program, and comparison of pre- and posttest results indicated a significant learning gain in most cases. The volume of sales of the SPC course to both Ford suppliers and non-suppliers provides further evidence of the success of the course. The results demonstrate the potential of interactive video for improving training for applications as complex as SPC. (16 references) (GL)
