This study emphasizes the contribution of LJIT practices and SCI for reducing the lead time. As time based competition intensifi es, organizations use various methods such as LJIT practices and SCI to reduce lead time. More specifi cally, this study suggests that lead time reduction attained through implementation of LJIT practices and SCI between with-in and between fi rms. This study emphasize that we can reduce the lead time by increasing the with-in fi rm and between fi rm levels of connectivity for sharing the information. The barrier to increase the supply chain connectivity in all the supply chain channels for any organization was not lack of technology or even lack of awareness of process modernizations, but the diffi culty in making the fundamental policy changes required to take advantages of these new technological and process modernizations. Even so, investing in developing high levels of connectivity and interdependency between with- in fi rm and between fi rms had helped to reduction in lead time.
