In the context of the digital economy, the experience-based decision-making and process fragmentation limitations of traditional personnel management systems are difficult to adapt to the needs of agility and precision. The research focuses on the inherent logic and practical path of system iteration, and proposes a collaborative transformation framework through three-dimensional analysis of technology, process, and organization and verification of state-owned enterprise cases. The technical dimension integrates big data and AI to achieve intelligent decision-making, the process dimension reconstructs full life cycle management, improves efficiency and experience, and the organizational dimension promotes the transformation of HR into a strategic partner.
