Employees demand high responsibility and empowerment, while keeping their work communal and flexible. Initiatives that foster organizational participation can contribute to the fulfilment of such work conditions. Research in sociology and psychology demonstrated positive effects on job satisfaction as well as productivity. However, although adoption of social software is widely spread in firms, research on the determinants of computer-supported organizational participation is scarce. We conduct 20 guided expert interviews to propose a research framework for computer-supported organizational participation. We describe the elements to consider when designing processes that aim to be beneficial for both the employer as well as the employees. Building on the expert interviews, our process model includes a topic horizon and a collaboration phase, which creates proposals that have to be decided on in order to produce results. We show how employee competence and leadership commitment are as important as the workload and supporting features as well as an option for anonymous communication. We propose a set of features and discuss implications for researchers and practitioners.
