As a growing body of research, the paper investigated the relation between some organization structural dimensions with regard to knowledge sharing practices. Researchers, however, have given little attention to the relation between the structural dimensions with regard to knowledge sharing practices in banking sector. The structural dimensions that this paper has focused on are Centralization and Coordination. Data for the experiment were collected in Kurdistan International Bank (KIB).

According to the findings, employees who are involved in the Loan Process of KIB, share knowledge and coordinate activities under a system that is a combination between centralization and decentralization. The work concludes with giving practical implications: it gives a number of recommendations for improving the performance of the Loan Process of KIB more effectively, a Business Process Management Framework, and implications for future research.
