Statistical Process Control

Definition: Statistical Process Control is a quality control method in which production processes are visually monitored.
SPC ensures that the process operates at its full potential, while making as much conforming product as possible with a minimum (if not an elimination) of variation (compared to the 'conforming product') and waste (rework or trash).
Comparable to Total Productive Maintenance, SPC emphasizes early detection and prevention of problems, rather than traditional post-manufacturing inspection and correction of problems after they have occurred.
Approaches used in SPC include control charts, continuous improvement and designed experiments.
