**8.3 Reduction of working time (D: Period)**

The BOSS team used fewer work-hours to complete their tasks. This is because the number of people engaged in one work is reduced by appropriately sharing the work under the leader's direction, and the work as a team is small. Also, in both cases, the BOSS team spent less time doing no work and had less rework. By eliminating waste and increasing efficiency, the overall working time could be shortened. The BOSS team's general work-hours for evacuation centers were shorter for the first experiment and longer in the second experiment than for the manual team. By doing so, the BOSS team achieved a reduction in overall working time, even though it does more work than the manual team. Although in the first appearance, the manual team had previously trained in the same workflow and remembered the workflow well, so it was impossible to see the effect of shortening the overall working time in the BOSS team.
