Statistical Process Control
Statistical Process Control (SPC) uses time-ordered data to distinguish routine variation from signals indicating meaningful process change. Rather than relying on isolated inspection or targets, SPC supports evidence-based decisions by focusing on patterns over time and understanding causes of variation (Oakland and Oakland, 2007; Mohammed, 2024).
Technique Overview
Statistical Process Control Definition
Statistical Process Control (SPC) is the application of statistical techniques, primarily control charts and process capability analysis, to monitor process performance over time. Its purpose is to identify special-cause variation, maintain stable operations, and support continuous improvement by linking signals in data to structured investigation and corrective action (Oakland and Oakland, 2007; Mohammed, 2024).
