I understand your opinion.
Following is additional point.
Sometimes I already mentioned in the meeting that representative from each department have to make communication with their department employees to inform what we decide in the meeting.
If there is problem in their departments and can’t solve the problem by each department, the representative should bring the problem in the TM Meeting.
Miyazaki san joined TMM or not … this is not key points. Because not only Miyazaki san but many other leaders or employees also don’t join the meeting.
Key point is lack of communication in Sales department.
