Overall Disclosure Profile

Sun* Inc. has established a system that accumulates knowledge from clients' business and product development and returns it to human capital education and subsequent projects. Its Vietnamese subsidiary has more than 1,000 engineers, linking education at overseas universities with company recruitment. It uses a system managing employees' skills, evaluations, and project experience for personnel allocation and applies AI in design, testing, and operational monitoring.

A distinguishing feature is the specific explanation of the cycle connecting specialist personnel, learning, and practical experience. However, participation in education programs differs from the number of people who acquired capabilities. Employee surveys identified correlations between supervisors and management and the overall score, while verification of development initiatives' effects remains a future issue. The filing explains that development productivity improved, but does not disclose the scale of improvement.

Scores by Assessment Item

Scores assess disclosures in the Annual Securities Report. A score of zero does not mean that an initiative is not implemented or that employees lack capability.

Filing Information

Assessment Scope & Disclaimer

This assessment is based solely on information disclosed in the company's Japanese-language Annual Securities Report filed through EDINET.

It does not assess the human capital initiatives a company actually implements or the company's human capital capabilities themselves.

Items for which no disclosure was identified in the Annual Securities Report receive no points, regardless of whether the company actually implements the relevant initiatives.

This English-language assessment is a translation of the original Japanese assessment and is provided for convenience. In the event of any discrepancy, the Japanese assessment prevails.
