New paper by B. Cleland, B. Galbraith, B. Quinn, and P. Humphreys: “The concept of Open Innovation, that inflows and outflows of knowledge can accelerate innovation, has attracted a great deal of research in recent years (Dahlander and Gann, 2010; Fredberg et al, 2008). At the same time there has been a growing policy interest in Open Government, based in part on the assumption that open processes in the public sector can enable private sector innovation (Yu and Robinson, 2012). However, as pointed out by Huizingh (2011), there is a lack of practical guidance for managers. Furthermore, the specific challenges of implementing Open Innovation in the public sector have not been adequately addressed (Lee et al., 2012). Recent literature on technology platforms suggests a potentially useful framework for understanding the processes that underpin Open Innovation (Janssen and Estevez, 2013; O’Reilly, 2011). The paper reviews the literature on Open Innovation, e-Government and Platforms in order to shed light on the challenges of Open Government. It has been proposed that re-thinking government as a platform provider offers significant opportunities for value creation (Orszag, 2009), but a deeper understanding of platform architecture will be required to properly exploit those opportunities. Based on an examination of the literature we identify the core issues that are likely to characterise this new phenomenon.”
