*6.2.1 Gantt chart*

**Figure 12** is a Gantt chart showing the work performed by five people in the manual team and the required time. The horizontal axis represents the time taken (minutes). The vertical axis represents the work done. Yellow is the work time for one person, orange is the time performed by multiple people simultaneously, and the gray shows the waiting time.

In the first half, it can be seen that work once completed can be resumed later. The waiting time is seen in the middle stage and the latter half. Some works were completed in the intermediate stage, and the members were unsure what to respond to next. A member who finished early waited for other members to complete their work in the second half.

One characteristic of the manual team is that the leader took the initiative and delivered it to other members.

**Figure 13** is a Gantt chart showing the work and time required by the five members of the BOSS team.

There is almost no rework, and each work is completed before moving on to the next work. Therefore, less waiting time is seen. In the latter half, some waiting time occurs. The time taken for all members to complete their works was defined as the work completion time by the team; the person who completed his work earlier waits for other members to finish theirs.

*6.2.2 Waiting time*

**Figure 14** shows each team's waiting time. **Figure 14(a)** shows the waiting time for the manual team, and **Figure 14(b)** shows the waiting time for the BOSS team.

It could be seen that the manual team had a longer waiting time than the BOSS team. In particular, according to the Gantt chart (**Figure 12**), Mr. E, Ms. G, and Ms. H continue to wait without any instructions during the work.

Also, regarding the BOSS team's waiting time, although Mr. K had a waiting time in the middle stage, the waiting time was not long (**Figure 14(b)**).

**Figure 15(a)** shows the number of tasks performed by the five members of the manual team. The number of tasks performed by the leader and the number of response tasks (simple tasks) is the largest. The leaders and members are working while discussing for the next task. The leader was not looking at the manual, but Ms. G and Ms. H checked occasionally. This is because the manual team prepared the works a day before the experiment (in advance), and the leader took the initiative. Looking at the Gantt chart, the manual team started the experiment without having a meeting to share the leader's response plan and instructions. In contrast, the BOSS team had time to hold a meeting with members to confirm the work
