Departmental performance evaluation is the engine for high-quality development of vocational colleges. Departmental performance appraisal is a comprehensive, standardized, and scientific evaluation of the work done by each department in talent cultivation, scientific research, and social services. The assessed departments include three categories: party and government management institutions, teaching institutions, and teaching support institutions. The assessment indicators include primary indicators, secondary indicators, tertiary indicators, etc. It can be seen that the data involved in performance evaluation is extremely large. The traditional work mode of hierarchical reporting and summarization of data is prone to errors in data statistics and summarization, and information correction and supplementation consume a lot of manpower and material resources, resulting in low work efficiency. In the context of informatization, based on digital empowerment, the way of data flow has been optimized to ensure the accuracy of adding, deleting, modifying, and querying massive performance evaluation data, saving a lot of manpower and material resources. From a technical perspective, reengineering the data flow process within the existing performance evaluation system to form a digital governance model for performance evaluation.
