<p>With the increasing demand for intensive management in enterprises, the Human Resource Shared Service Center (HRSSC) has become a key carrier for improving organizational efficiency. This article takes R Group’s HRSSC as the research object and constructs a multidimensional performance evaluation system of “finance customer operation learning growth” based on the Balanced Scorecard (BSC) theory. The weights of indicators are determined through the Analytic Hierarchy Process (AHP), such as the first level indicators of finance, customers, operations, and learning growth; Secondary indicators include 10 secondary indicators such as cost reduction, efficiency improvement, customer satisfaction enhancement, customer complaint rate reduction, and system application status; And 20 third level indicators were included, and through weight calculation, it was found that the CR value was below 0.1, passing the consistency test. Finally, using the fuzzy comprehensive evaluation matrix, each third level indicator factor was evaluated, and it was found that R Group had a maximum membership degree of 0.478 in the financial dimension, indicating a good evaluation; The maximum membership degree of the customer dimension is 0.707, and the evaluation is average; The maximum membership degree for the operational dimension is 0.416, rated as average, while the maximum membership degree for the learning and growth dimension is 0.596, rated as average. Overall, all have achieved excellent evaluations, and R Group’s human resources shared services need further improvement. Based on this, operational optimization suggestions are proposed, including building a financial system for personnel, providing expert and partner channels for the three pillars of human resources, etc., to provide methodological references for HRSSC performance management in similar enterprises.</p>
