**5. Results of the first experiment**

For the first experiment, the manual team had 23.5 minutes to complete the work, and the total number of work was 17. On the other hand, the BOSS team had 20.5 minutes to complete the work, and the total number of work was 24. The BOSS team carried out more works than the manual team.

The hypothesis is that manual teams do not take instructions from the leader and everyone tends to do the same work and duplicate the work. While on the other hand, the BOSS team leader gives instructions to the members, and each person works in parallel at the same time. It is conceivable that the work was achieved while being aware of the division of roles. Here, this research will verify the hypothesis by analyzing the leader's actions and each member while comparing the manual team and the BOSS team centering on the Gantt chart.

#### **5.1 Gantt chart**

**Figure 5** shows the Gantt chart of three members in a manual team. The horizontal axis is the time (minutes), the vertical axis is the working name, yellow is the working time to complete a task by one person, orange is the work done by multiple people simultaneously. Gray represents the waiting time. Once all three members of the manual team finish the same work, they do the same work again in the second half, and there is much rework. However, time is running out.

On the other hand, **Figure 6** is a Gantt chart of three BOSS teams. Mr. C and Mr. D (like Mr. C and Ms. D for convenience in this research) have finished the work they started once and then moved on to the next work, and there is almost no rework. Incidentally, after 19 minutes, Mr. C seems to have accumulated from the start of the work because he was waiting for other members to finish their works. After that, contact sharing was started, and the work status was confirmed as a whole. Overall, the BOSS team did not see any rework in simple work and did not observe any waitings.

The big difference between the manual team leader and the BOSS team leader is that the manual team leader tends to do the same work as the member, but the

leader of the BOSS team instructs the members to work. The BOSS team leader tended to be around receptions to operate the BOSS, manage overall progress, and

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

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
