Employee performance is one of the key indicators of an organization's success in achieving its strategic goals. This study aims to examine the effect of work discipline and communication on employee performance through a literature review approach. The research method employed is descriptive analysis by reviewing secondary sources, including national and international journal articles, conference proceedings, and relevant human resource management textbooks. The findings indicate that work discipline, reflected through rule compliance, punctuality, and employee responsibility, consistently shows a positive and significant effect on employee performance across various types of organizations, both in the private sector and government institutions. Communication, whether internal or interpersonal, also demonstrates a positive effect on performance because it reduces misunderstanding, accelerates coordination between work units, and increases employee engagement in achieving organizational goals. Several studies found that work discipline and communication simultaneously exert a greater influence on performance compared to their partial effects, although some studies show the dominance of one variable depending on organizational characteristics. The effectiveness of these two factors largely depends on organizational context, leadership style, and prevailing work culture. From the perspective of human relations theory, sound interpersonal relationships supported by effective communication and strong discipline create a conducive work climate for productivity improvement. Therefore, strengthening work discipline and managing organizational communication effectively become important strategies for companies to sustainably improve employee performance.
