International Journal of Information Studies Nurdin Nurdin, Khaeruddin Yusuf 10 2 2018 http://www.dline.info/ijis/fulltext/v10n2/ijisv10n2_3.pdf Literature addressed how conventional banks have successfully implemented knowledge management strategy using various models to support their business performance. Meanwhile, limited studies have been proposed regarding how Islamic banks manage different knowledge to support their business process. By using knowledge management lifecycle theory, the authors studied knowledge management process within two branches of Islamic Banks in Central Sulawesi. Data were gathered through observation, written material, and in-depth interviews with key informants from both banks. The findings show the knowledge management lifecycle model within Islamic banks does not necessarily follow the theoretical model built in conventional banking organizations because Islamic banks have unique characteristics. Islamic banks have to integrate the knowledge into Islamic values and norms before it is stored, shared, used, and improved as showed in the theoretical construct. As a result, the knowledge management lifecycle model was revised according to Islamic banks characteristics.
