ABSTRACT This study investigates the influence of a supportive work environment and organisational learning culture (OLC) on organisational performance with a serial mediation of learning agility and organisational innovation. Data was collected from 379 entry and middle-level information technology (IT) professionals. Structural equation modelling (SEM) and bootstrapping approach were utilised to assess the proposed hypotheses. Results indicate that both a supportive work environment and learning agility have a significant and positive impact on organisational innovation. In addition, learning agility was significantly correlated with organisational performance. Learning agility and organisational innovation had a serial mediating role in the indirect effect of a supportive work environment and OLC on organisational performance. This is the first known study to highlight that both a supportive work environment and OLC are essential for enhancing organisational performance through learning agility and organisational innovation in IT companies.
