Complex innovation incorporates more than one innovation type. Using the number of dimensions of the ‘most significant innovation’ implemented by each public employee’s workgroup as a proxy for innovation complexity, this study explores factors that are associated with complexity and examines how complexity affects innovation outcomes. Employing a sample of 4,369 Australian Government employees, we find that the more complex the innovation, the greater the number of barriers a workgroup has to face in its implementation. A broader (but selective) range of idea sources and a more decentralized workplace where both individual and team creativity is encouraged increase the likelihood of implementing complex innovations. Innovation complexity is positively correlated with the variety of beneficial outcomes, suggesting both policy and management interest in supporting complex innovation in the public sector.
