The c chart is used to monitor the count of defects per unit and is appropriate when the sample size is constant. If the c chart suggests a special cause of variation, it means that there is an assignable cause or an unusual fluctuation in the process, which should be identified and eliminated to improve the quality of the process. Therefore, incorporating the special cause into the permanent ongoing process would help maintain the improved quality.
