**8.2 Reduction of the burden on the operator (C: Cost)**

The use of the BOSS clarified the instructions of the leader. Under clear instructions, it is considered that the staff can move quickly, and it is unlikely that there will be a difference in movement due to experience. Therefore, it will be easier to grasp the workflow of the whole work, and it will be possible for even inexperienced leaders to give appropriate instructions.
