**■Decision to Implement for Promoting a Comfortable Working Environment through Data-Driven Personnel Placement and Development** Arakawa City is working to improve the capabilities of its employees to provide tailor-made services that cater to each resident, based on a high level of professionalism in public service.

However, some parts of personnel evaluations were still managed using paper and Excel, which required significant time and effort for document distribution, collection, and aggregation.

Furthermore, information such as employee transfers, promotion selections, and training histories was dispersed, making optimal personnel placement a challenge.

To address these issues and promote a comfortable working environment by centralizing employee HR information, evaluation results, training histories, and qualification data, and realizing data-driven personnel placement and development, Arakawa City decided to implement "Talent Palette."

**■Utilizing AI and Human Resource Data to Prevent Turnover, Strengthen Recruitment Activities, and Improve the Quality of Citizen Services** The introduction of Talent Palette will not only streamline HR operations through the digitization of paper-based tasks but also enable effective talent development by leveraging evaluation results and skill information.

Traditionally, personnel assignments were manually handled by 담당職員 (staff in charge), considering factors such as maternity/paternity leave schedules, sick leave status, return-to-work plans, and promotion schedules. With Talent Palette, human resource data and AI-driven transfer simulations will optimize assignment processes, reflecting employee preferences and aptitudes with greater accuracy, thereby contributing to creating a workplace where employees can thrive.

By optimizing personnel allocation with AI, early detection of signs of employee turnover, and career development support, Arakawa City aims to prevent turnover, strengthen recruitment activities, and improve the quality of public services.
