was opened. The scenario, such as "for home-care patients with a positive PCR test, contact a medical institution. I started to carry it" was prepared in this experiment. Both teams need to report and share the situation with the ward headquarters that it is ready.

On the other hand, in the second experiment, the teams did not contact the ward headquarters, only the evacuation shelter was opened, and the differences between the manual and BOSS teams were analyzed.

Regarding the use of the facilities in the experiment, the first team was to use only the gymnasium, and the equipment such as classrooms, toilets were set up virtually.

The following five suggestions were used in the verification process. (1) For time, the minimum unit was 30 seconds = 0.5 minutes, and work-hours were recorded. (2) Regarding the operator's movement, a fixed video camera was installed, and the operator's movement was confirmed. (3) Regarding the leader's instructions, the activities were recorded with a voice recorder including the leader's statement. (4) Regarding the omissions of work, the manual and BOSS contents were compared with the contents of work performed during the verification test. (5) Regarding the participants' impressions and opinions, this research conducted a questionnaire survey and grasped the work's impressions.
