JITSU means “Just In Time Supply” and stands for an uncomplicated reordering system. Everybody talks about Industry 4.0, which means production on demand. Everything is controlled by technology, but important is the human being in between, who at any time needs the material at the working place wherever he manufactures. And that without any walking distance or waiting time, that is the goal what needs to be achieved. In spite of using the most modern IT, the staff still needs to get their expandable materials (C-parts) themselves – resulting in expensive production stops. JITSU sets an end to this supply gap!
