Star League Inc. (Headquarters: Shibuya-ku, Tokyo; Representative Director: Takahiro Chuba) announced on July 2, 2026, the release of a new research report, "Theory Supporting Strategic Personnel Selection," added to its "Decider® Management Research" series, which includes findings from academic research. ■ Executive Summary Research on Japanese listed companies has identified a fundamental competitiveness issue: the theorization of management plans. Focusing on the depletion of human resources, this report organizes a framework for personnel selection in line with the latest trends in management science. It goes beyond presenting fragmented insights from various studies, adding unique interpretations tailored for practical application, and can be used as an actionable white paper. Insufficient human resources are behind the low achievement rates of medium-term management plans. Opportunity cost for top management changes is estimated at 200 million yen; selection of low-risk middle management becomes the focus. In uncertain environments, democratic lottery systems are regaining prominence, modernized by combining them with qualification verification. Breakthroughs are expected from selection systems that primarily observe performance output. A talent pool focusing on personality, rather than outdated demographic attributes, is most crucial. ■ Report This report can be downloaded free of charge from the following URL: https://www.star.careers/biz/organization/selection-under-uncertainty/ ■ About Decider® Management Research This is proprietary research aimed at disseminating new knowledge, such as academic findings, into the practical business field, focusing on management challenges.
