This study investigates how individual creativity is related to the quality of team decision processes and team climate, and the mediating role of team decision processes between individual creativity and team climate. A multi-level theoretical model was proposed and partial least squares structural equation modelling (PLS-SEM) was conducted on a sample of 139 software development projects. The results suggest that: (i) individual creativity improves the quality of team decision processes, (ii) team decision processes are positively associated with four dimensions of team climate (organizational support, innovation orientation, goal orientation and informal structure), and (iii) team decision processes partially mediate between individual creativity and team climate. In particular, the obtained results stress the role of individual creativity in the formation and evolution of a positive climate by means of team decision processes. The study implies that managers should recognize the value of creative individuals as the basic source of competitive advantage and success. It further discusses the managerial implications of the findings as well as limitations and constructive new directions for future studies to improve software development team performance.
