The literature presents numerous methods and practices for facilitating organizational innovation capabilities. Less attention has been paid to indicating the actual impact of these methods on different aspects of innovation capability. The current study focuses on this issue by examining three methods developed to facilitate organizational innovation capabilities and their effects on different aspects of innovation capabilities. The study uses the multiple-case study approach, focusing on the effects of the Handbook of Innovation, Theatre-based methods, and an Innovation Session on innovation capability and how these effects appear in different organizational contexts. The essential issues related to the positive effects of the methods on innovation capability are explored. The study contributes to the literature by showing that innovation capability can be developed by utilizing different kinds of participative methods. In addition, the study contributes to the current literature by presenting what kind of methods can be used to develop certain aspects of innovation capability and how the development works could be organized. The outcome helps managers of organizations select the most suitable method for developing innovation capability. This selection depends on the aspect of the innovation capability that the organization wishes to develop. The study also presents important issues that should be considered when developing innovation capability.
