Statistical Process Control (SPC)

Move towards prevention-based quality control. Measure, monitor, and improve process capability with data-driven insights.

Quality Control

Scientific Process Monitoring


Statistical Process Control (SPC) employs statistical methods to measure and eliminate special cause variation. It shifts the focus from detection-based to prevention-based quality control. By monitoring SPC charts, organizations can predict process behavior and take proactive measures.

Process Capability (Cp, Cpk)

Process capability assesses the ability of a process to meet specifications. Potential capability (Cp) and actual capability (Cpk) are key estimates. They reflect the nonconformance rate by expressing performance as a single number, typically a ratio of specification limits to process spread. These metrics are invaluable for evaluating both initial and ongoing capability.

Process Variation

A stable process displays common cause variation—variation inherent to the process. If a process is unstable, it shows special cause variation from external, non-random factors. SPC helps distinguish between the two, allowing you to stabilize processes and predict future performance within defined limits.
