How often should a Control Plan be reviewed and updated?

The frequency of reviewing and updating a Control Plan is crucial for maintaining process integrity and achieving consistent quality. Whenever there is a process change, it becomes necessary to evaluate and potentially revise the Control Plan to ensure that all relevant controls and measures align with the new process dynamics. This might include adjustments to the monitoring methods, the types of controls in place, or even the key performance indicators that are being tracked.

Reviewing and updating the Control Plan in response to changes helps organizations adapt their processes to new conditions effectively, thereby reducing the risk of errors and improving overall performance. This approach aligns with the principles of continuous improvement and quality management, ensuring that the methodology remains relevant and effective in achieving desired outcomes. Other frequencies such as annually, monthly, or only addressing issues may not be responsive enough to ensure that the Control Plan is continuously aligned with the current state of the process.
