Final answer:
Control charts are used in quality control to assess process stability by monitoring performance and identifying whether the process variability is within acceptable limits over time.
Step-by-step explanation:
Control charts are tools used in the field of quality control to track whether a process is functioning within certain bounds. In regard to the question posed, control charts allow one to assess C. Process stability.
They are a type of run chart that provides a graphical representation of a process over time and are useful for monitoring process performance. Including a process's mean and variance, control charts help determine if a process is stable and consistent over time or if it is subject to unusual variations that could indicate problems.
While control charts can indirectly relate to other aspects such as process capability or customer satisfaction by providing data on process performance, they are primarily focused on stability and statistical process control (SPC).
It is important to note that the use of experimental controls, as mentioned in the provided reference information, pertains to the design of experiments and has a different context compared to process control where stability is being monitored via control charts.
