Today, Japanese industry has been faced to lose many middle-aged technicians because of their retirements. These technicians have been contributing to success of Japanese industry, so that their skills should be passed to younger generations. However, these technicians tend to not have any written manuals for their work, so their skills were developed by their experiences and senses. Therefore, passing all skills to younger generations are difficult, especially at medium and small companies. We have been developing systems "processing templates," which help to pass techniques to young workers. In this paper, we report about "the system of collecting techniques" and "the technique digitizer," which is a tool that digitizes technician's skills collected by the system of collecting techniques.
