This study is an empirical test of an adaptation of the DeLone and McLean Information System (SI) success model in the context of human resource management in a Moroccan public administration. The model has 6 dimensions: quality of information, quality of system, quality of service, use, user satisfaction and perceived net benefit. The auxiliary condition demonstrating strategies were connected to the information collected from a survey, given over to 120 officials of a large Moroccan ministry. The hypothetical relationships between the six success variables are largely confirmed by the data. The results obtained have several important implications on the topic of human resources research and practices too. This article concludes by talking about the impediments of the research, which ought to be tended to in future investigate.
