This research examines the relationships between Six Sigma, organizational learning and organizational innovation and the impact of Six Sigma on organizational learning and organizational behavior. Our findings reveal that Six Sigma exerts a complete mediating effect on organizational innovation through organization learning. Six Sigma role structure, Six Sigma structured improvement methodology and focus on metrics enhances commitment to learning, shared vision and open‐mindedness thereby promoting organizational learning. On the other hand, Six Sigma focus on role structure and metrics have positive effect on both administrative and technical innovations. Thus, this paper suggest that when assessing and formulating measures like Six Sigma for promoting organizational innovation, organizations should consider the mediator variable of organizational learning to avoid misjudgment and achieve better performance. On the other hand, this study finds no evidence of organization type exerting moderating effect on the impact of Six Sigma on organizational learning. However, the relationship between organization type and organizational learning could merit further exploration on this research issue. The contributions of this study lie in offering new directions of exploration and widening the scope of Six Sigma, organizational learning and innovation
