5. Future Research Implications This study proposed the of collaboration that can be categorized into three dimension levels of concept SCC (information sharing, decision synchronisation, incentive alignment). The results show that SCC has positive effect (such as cost reduction and operational flexibility) on firms and that the effect is a long-term effect. Three contributions to scCappear from the results of the study. First, the study has developed reliable a and valid instrument to measure the extent of collaboration that incorporates information sharing, decision synchronisation, and incentive alignment. The item statements can be tailored to the specific relationship to gauge te levels of collaboration practices and used to identify the gaps that need to be eliminated. Second, the study shows that there is a significant correlation between collaboration index and operational performance. It suggested that the chain members build collaborative efforts to seek opportunities to improve overall performance. Third, the study also shows that three dimensions of collaboration significantly affect competitive advantage and organizational performance. It is advised that chain members should develop a dialogue to carefully discuss initiatives for improving the practice, which makes the greater contribution to better performance. 6.
