Control charts play a crucial role in quality management by monitoring the variability in a process over time. They are graphical tools that help organizations track performance metrics to determine whether a process is in a state of control or if there are variations that may signal underlying issues. By plotting data points over time and establishing upper and lower control limits, control charts allow businesses to visualize trends, detect shifts, or identify outliers in the process. This ongoing monitoring helps to ensure that processes remain stable and predictable, which is essential for maintaining quality standards.

The other options are not as suitable for the primary function of control charts. While identifying the mean of a dataset is a statistical concept, it does not capture the essence of monitoring processes over time. Periodically assessing employee performance is more related to performance management rather than a direct application of control charts. Finally, while comparing the effectiveness of different processes can be valuable, control charts specifically focus on monitoring a single process's variability rather than making comparative assessments.
