This survey aims to assess the effectiveness of Islamic organizational culture currently applied in a broadcasting company in Indonesia. This study will evaluate its strengths and weaknesses, as future developments and organizational changes references. To achieve this goal, data were collected from all 45 employees, using the Denison Organizational Culture Survey (DOCS). This survey measures cultural indexes incorporated into four organizational cultural traits that have been proven to sustain a strong influence on organizational effectiveness: involvement, consistency, adaptability and mission (Denison, 2014). The measurement results indicate that measured organizational culture has a greater focus on the internal aspects, like employee performance, than external aspects such as customer satisfaction and innovation. Furthermore, the Islamic organizational culture used, obtains quite optimal measurement results, at consistency and involvement trait which able to achieve scores at the third and fourth quartiles. However, organizations still need to optimize adaptability and mission traits, which scores only capable to achieve first and second quartiles. The lowest value obtained in the goals and objective index, also shows that organizations need to evaluate the clarity of short-term and long-term goals related to accomplishing the company's vision.
