Innovation is very important for an organization to gain and maintain its competitive advantage. In order to increase organizational innovation, individual roles from its members are needed, especially in innovative behavior.

The study was conducted on 277 employees of PT Telkom Indonesia Tbk. Respondents filled out questionnaires to assess the elements of transformational leadership, psychological capital, knowledge sharing, and innovative work behavior. The Structural Equation Modeling (SEM) method was used to show a causal relationship between variables. The results showed that transformational leadership did not significantly affect innovative work behavior. Even so, psychological capital and knowledge sharing fully mediated the transformational leadership and innovative work behavior relationship.
