Universities play an important role in motivating young graduates to become technology entrepreneurs. The objectives of this research are to investigate the success factors for business incubators and to develop and propose a framework of successful business incubators for public universities in Indonesia. Indonesian public universities that have business incubators were considered for this research. A preliminary study was conducted with a panel of experts who have the necessary insights and experiences in managing both the incubators and the relationships within the incubators with the tenant firms. This research examines some significant measures with reference to the unique features of university business incubators in order to better understand the manner in which incubators can be assessed in a developing country. The result of this research includes a framework of successful business incubators in Indonesian public universities. This framework is developed on the basis of previous studies and the preliminary study conducted with ten business incubator experts.
