When a process is neither capable nor in control, the first step is to identify and remove any special causes of variation. This is because it is important to first stabilize the process before attempting to improve its capability. In contrast, removing common causes of variation may not be as effective in improving the process capability, as these are inherent to the process and are not easily eliminated. Redesigning equipment or determining the process capability index should only be done after the special causes of variation have been addressed.
