This research used reliability and validity test .Then, path analysis with linear regression to prove the mediation effect was used for the data-analysis. The results showed that there is a statistically significant impact of the dimensions of SCM practice on the conformance, information sharing and integration have significant effect on time to market, information sharing and customer management have significant effect on cost, information sharing and supplier management have significant effect on reliability . The results shows that the mediating effect of customer orientation has significantly partial affect the relationship between SCM practice (information sharing, integration) and operational performance (reliability). Since competitor orientation mediating the relationship between information sharing and reliability. Furthermore, a new dimension was developed in operational performance (time to market, cost, conformance and reliability) .since if manufacturing companies focus on market orientation on their SCM practice , the operational performance increased , moreover the organizational performance increased and customer satisfy .
