Abstract
The foundation of family businesses to continue their existence from generation to generation by growing in a healthy way as desired goes through the process of institutionalization. Institutionalization, on the other hand, is possible with the support of entrepreneurial leaders, who manage enterprises not with the personal administrations of their founders but correctly by adhering to procedures, standards and methods in order to positively affect their future. In this study, which aims to reveal the effect of entrepreneurial leadership on institutionalization, efforts of two leading businessmen living in different countries to institutionalize their companies and their practices in this direction were analyzed with the case study method. In order to obtain data, the Turkish businessman Ahmet Keleşoğlu and his organization Selçuk Ecza Deposu A.Ş., and the German businessman Robert Bosch and his company Bosch GmbH were examined by interviews, corporate/foundation websites, CD’s, books, magazines and document review methods. As a result of the findings, it was concluded that both businessmen owned entrepreneurial leadership characteristics and that entrepreneurial leadership can affect institutionalization. It is also among the results of the study that proactivity, risk taking, vision, seizing opportunities, innovation and creativity which are sub-dimensions of entrepreneurial leadership, can affect institutionalization.
