To more efficiently create after-sales service reports (work reports and proposals) of higher quality by field service engineers, a report creation support system utilizing generative AI was developed. In the past, there were key challenges, such as the heavy workload required to create reports on-site and variation in the quality of the reports, as well as a significant operational burden associated with pre-work preparation and post-work processing. With the introduction of this system, work reports could be generated in real time and proposals could be prepared at an accelerated rate, while high operational feasibility could be secured by integrating existing operational systems and implementing measures against communication environment issues. As a result, improvement in operational efficiency and enhanced responsiveness to customers could be achieved, contributing to higher customer satisfaction.
