Abstract
This article analyses from an institutional perspective efforts by two entrepreneurs in governmental organizations to promote new practices and programmes and the nature of the challenges they encounter as they deviate from, and attempt to disrupt, institutionalized practices. These two case studies are used to gain knowledge on why and how individuals become institutional entrepreneurs. The article provides insights into the processes an institutional entrepreneur goes through in an institution that does not provide support. The authors finally suggest potential avenues for cross-fertilization between the corporate entrepreneurship and institutional entrepreneurship literatures.
