Definition
Systematized management of vendor quality.
In detail
Supplier Quality Management (SQM) is a systematic approach to managing supplier product quality, delivery performance, and process capability, aiming to ensure supply chain stability and reduce quality risk. It addresses the impact of external incoming material quality issues on production and customer satisfaction. Unlike internal quality management, SQM emphasizes supplier qualification, performance evaluation, and continuous improvement. Typical outputs include supplier scorecards, audit reports, and improvement plans.
Example in practice
An electronics manufacturer frequently experienced production line stoppages due to defective key components from suppliers. The quality department introduced an SQM system, managing suppliers by tier and evaluating metrics such as PPM and on-time delivery rate monthly. For underperforming suppliers, they stationed engineers to assist with improvements. A year later, incoming material defect rates significantly decreased, and production stability improved.
