Variations in quality that are due to factors such as machine tools wearing out are examples of assignable causes. Assignable causes are specific and identifiable sources of variation that can be corrected in order to improve the quality of the output. Common causes, on the other hand, are sources of variation that are inherent in the system and cannot be controlled. Control causes refer to factors that are managed by the production process itself.
