The research was motivated by the phenomenon of inconsistent employee performance, as reflected in the daily service performance indicators (Item Per Labor Hour/IPLH) across various branches. Additionally, employees’ innovative work behavior is considered critical for organizational success. This study employed a quantitative approach, with data collected from 60 full-time employees through a survey using structured questionnaires. Data analysis was conducted using the SmartPLS 4 software to examine the structural model and the relationships among variables. The results indicate that transformational leadership does not significantly influence innovative work behavior. However, transformational leadership has a significant positive effect on individual task performance. Furthermore, knowledge sharing was found to mediate the relationship between transformational leadership and innovative work behavior but did not mediate the relationship between transformational leadership and individual task performance. Practically, these findings provide guidance for the management of Coffee Shop XYZ to enhance employee performance through effective knowledge sharing strategies. Thus, fostering transformational leadership and promoting knowledge sharing in the workplace can be effective strategies to drive innovation and improve employee productivity at Coffee Shop XYZ.
