ABSTRACT: This study aims to analyze the relationship between management information systems, work discipline, and leadership on employee performance. This study used a quantitative approach with a survey method of employees in a public sector organization. The study population was 154 employees of the Tirta Amertha Jati Regional Drinking Water Company in Jembrana Regency, Bali, Indonesia. This study used saturated sampling, meaning the entire population was selected as the sample. Data collection used questionnaires distributed to respondents. Data were analyzed using PLS SEM to test for direct and moderating effects. The results showed that management information systems had a positive and significant effect on employee performance. Furthermore, work discipline and leadership were shown to mediate this relationship. Therefore, the effective use of management information systems will drive improved performance if supported by high discipline and leadership capable of providing direction, motivation, and supervision.
