A quality management system that uses statistical techniques to monitor and control process variability in real time.

Adopts a front‑end/back‑end decoupled architecture and supports full data import/export.
The system includes OOC/OOS and eight major rule configurations, along with multiple control charts (such as X‑Bar, R, and P charts), enabling real‑time monitoring of processes and historical data.
When an out‑of‑control or out‑of‑spec condition occurs, the system automatically sends alerts via email, LINE, or WeChat, and immediately holds the affected lots, raw materials, or equipment, helping the factory perform preventive quality control and improve production efficiency.
