Common Cause Variation VS Special Cause Variation | PQI

Описание: Common cause variation and special cause variation represent different types of fluctuations in a process. Common cause variation is inherent to the process, predictable, and results from the normal, everyday factors affecting the process. Special cause variation, on the other hand, is unpredictable, stems from specific, unusual events or factors outside the usual process, and indicates that the process is out of statistical control.
