Supply Chain Information Sharing: Modeling the Barriers

The purpose of this paper is to present an approach for modeling the barriers of information sharing (IS) in supply chain (SC) by developing the relationship between various information sharing barriers (ISBs). Using interpretive structural modeling (ISM), the result shows a hierarchy-based model and the mutual relationships among the ISBs. The result shows that there is a group of ISBs having high driving power and low dependence which requires maximum attention and of strategic importance while another group consists of those ISBs which have high dependence and are the resultant actions. This categorization provides an important guideline to top management to differentiate between independent and dependent ISBs and their mutual relationships which are playing the role of roadblocks for effective IS in SC.
