Purpose - This paper aims to explore how employee performance is impacted by factors such as teamwork, communication competence, and employee competence in several countries and industries. Currently, there is no existing literature that acknowledges aspects related to teamwork, communication competence, and employee competence impact on employee performance within the context of a Indonesian public service organization.
 Design/Methodology/Approach - The study employs a quantitative method using a path analysis model. This study involved the analysis of data from 205 employees working in a public service organization. The reliability and validity of the questionnaire items are conducted via Kaiser-Meyer-Olkin (KMO) analysis, and the related hypotheses are tested using the path analysis model.
 Findings - The results showed the positive impact of teamwork, communication competence, and employee competence on employee performance. Additionally, employee competence mediated the influences of teamwork and employee performance. Also, employee competence mediated the impacts of communication competence and employee performance.
 Research Implications - The research was conducted within a specific Indonesian public service organization, making it challenging to apply the findings universally across various sectors and international contexts. The results of the research hold the promise to assist leaders within public service organizations in creating approaches that enhance the skills of employees. This involves designing impactful human resource development initiatives and boosting the employee capacity to reach the organization’s intended aims and objectives. The study is new in its effort to bring together four frameworks to create a novel performance model explaining the importance of teamwork and communication competence with employee competence and employee performance.
