■ Training Implementation Overview

Implementing Municipality: Minamiboso City, Chiba Prefecture

Training Curriculum: Introductory Level

Number of Participants: Approximately 85 in total (Morning: approx. 30 on-site, 15 online; Afternoon: approx. 30 on-site, 10 online)

Participant Characteristics: Many have experience using generative AI in their private lives. The participants were primarily mid-career to managerial staff seeking concrete application methods for their work.

■ Training Enthusiasm Spreads Through Staff Word-of-Mouth

A particularly impressive aspect of this training was that a staff member who attended the morning session encouraged colleagues by saying, "The training was great, you should participate," leading to requests for spontaneous participation in the afternoon session.

The fact that the training content naturally spread among staff and generated additional participants is a testament to its accurate response to on-site needs.

Throughout the training, numerous practical questions directly related to work were raised, such as "How can this be applied to XX tasks?" and "Please teach me how to write prompts that minimize information leakage risks."
The earnest atmosphere throughout the venue conveyed that each participant attended with a clear objective of improving their work.

■ High Writing Skills Serve as a Foundation for AI Utilization

Minamiboso City was formed through the merger of six towns and one village, and has long been engaged in meticulous and layered plan development while coordinating diverse regional characteristics. The high skill level of its staff in logically and accurately articulating administrative challenges, cultivated through this process, is a significant strength in improving work efficiency using generative AI.
During the exercises, participants were observed smoothly translating their thoughts into precise language and formulating them into prompts.
Additionally, feedback was received stating, "The instructor's pacing was good, and because they understood the municipality's internal situation, the training captured the staff's interest."

■ Comments from the Person in Charge (Morita)

"The staff of Minamiboso City have a very clear objective for work improvement, and during the exercises, their stance of posing their own work challenges to AI was outstanding. We expect that this training will serve as a catalyst for QommonsAI utilization to spread from mid-career and managerial levels to younger staff through a top-down approach.
We will strive to provide continuous follow-up support in collaboration with the digital affairs department to ensure its full-scale adoption throughout the city."
