Intelligence is individual capacity to act appropriate with purpose, think rationally, and adjust with environmental conditions. A successful company is related with the intelligence and ability of its leader to create excellent strategies to be a winner in a competition. High competition occurs among cellular operators in Indonesia. The big-five companies in telecommunication industry are PT. Telkomsel Tbk., PT. XL Axiata Tbk., PT. Indosat Tbk., PT. Telkom Tbk., and PT. Bakrie Telecom Tbk.. Intelligence development is a main focus for an individual to be an effective leader in every situation. The purpose of this research is to find out more about leader intelligence in telecommunication industry. This research uses survey and descriptive method. Operational variables consist of intellectual intelligence (X0, emotional intelligence (X2), spiritual intelligence (X3), and adversity intelligence (X4). We use the Likert type as a scale of quetionaire. We use convenience sampling as a sampling technique. Results from data processing show that intellectual intelligence, emotional intelligence, spiritual intelligence, and adversity intelligence of leader in telecommunication industry are included in high category with an average percentage of 77.95%. There is no dominant intelligence that is needed to be a successful leader. The main focus is how leaders can synergize all the intelligence that they have to solve a problem, and they must also realize that changes in the telecommunication industry are very fast, so they must familiarize themselves to uncertain situations. 展开更多
