Data for the study were gathered via questionnaire answers, and with the use of the SEM PLS software, SEM techniques were used for analysis. Data analysis findings indicate that training, supervision, workload, incentives, and motivation all have a major impact on service quality. According to this conclusion, the quality of the resultant service improves with the amount of these five variables. Nevertheless, there is no meaningful correlation between the reward variable and service quality.
