Statistical Process Control (SPC)

Monitor process variation in real time and intervene before defects occur.

The Problem

Quality issues are detected at inspection — after defects have already been produced. Without SPC, process drift goes undetected until scrap or customer returns appear.

Our Approach

Real-time SPC that continuously monitors critical process parameters using control charts, automatically detects drift using Western Electric rules, and alerts operators before the process goes out of control.

Expected Outcome

Shift quality assurance from detection to prevention — catch process drift before it creates defects, reduce scrap, and improve process capability indices.

What's Included

Real-time control charts (Xbar-R, Xbar-S, I-MR, P, NP, C, U)
Western Electric rules violation detection
Critical parameter monitoring per machine and product
Cpk and Ppk capability reporting
Automatic alerts on rule violations
Integration with MACHHUB for real-time process data
