MSIL Audit Checklist:
Ensuring quality and consistency in supplier systems is critical for every automotive manufacturer, but it holds particular importance for leaders like Maruti Suzuki India Ltd. (MSIL). The Maruti Vendor System Audit Checklist, also known as the Vendor System Assessment (VSA) or MACE Audit, serves as a comprehensive evaluation tool designed for Tier-2 vendors. With its structured 19-point framework, it helps auditors assess vital areas such as production preparation, initial production control, change management, standards implementation, and safety compliance.
