Abstract
This article investigates the benefit of participation in policymaking. Based on data from interviews with various interest groups, private organisations, and representatives of regions that had been involved in recent policymaking processes in Switzerland, this study analyses the relationship between participation and satisfaction with the policy outcome. The study looks at two different aspects of outcome satisfaction: perceived consensus of a decision and preference attainment. The results show that the level of participation is related to both aspects of outcome satisfaction but that the strength of association is dependent on the type of interest group and the level of conflict among the groups participating in the decision-making process.
