Question

Quizplus · Accepted Answer

The statement suggests that there is a specific and identifiable cause (improper machine maintenance) that is leading to the production of scrap products, which is a special cause of variation. Special causes are specific, unusual events or circumstances that can be isolated and addressed through targeted improvements or interventions. In contrast, common causes of variation are inherent in the production process and cannot be attributed to any specific factors, but can be managed through ongoing process improvements.
