The fundamental reason for this study was to explore the impact of Supply Chain Integration on Operational Performance through the directing part of Lean Operations. The study essential information gathered from the example that contains 288 supervisors working in Saudi Industrial Organizations lied in the western locale, utilizing an all-around planned survey. This study coordinated to study how the supply chain integration, lean operations, and operational performance can impact each other in manufacturing associations. SEM model created and deliberately surveyed and tried. The key discoveries demonstrate that rehearsing supply chain integration cycles could bring about expanding the open door for manufacturing associations to accomplish operational performance through applying lean practices. Therefore, the connection between supply chain integration and operational performance, just as the connection between lean operations and operational performance, was positive, given these connections, it very well may be presumed that the lean operations (as a directing variable) can have a positive impact the connection between supply chain integration and operational performance. Particularly, the connection between supply chain integration and quality performance measures.
