Quizplus · Accepted Answer

Common causes are also known as random causes or chance causes. These are natural variations in the production output that are inherent in the process and cannot be eliminated completely. Assignable causes, on the other hand, are those that can be traced to a specific source and can be eliminated or controlled. Control causes are not a recognized term in quality management.
