Generally yes, one would likely use SPC within a Quality Management framework.
Another way of seeing from a graphical / data point of view, is a process can have an “allowable” level of variation which is calculated using your standard deviation (in a basic sense) when your process data fits within this level of variation (which you can see on an SPC chart as Control Limits) in effect it is saying that you’re process is “Statistically In Control” – which in a simple sense means that your process is stable, with no obvious signs of trends, patterns, or outliers that could be leading to defects or defective items.
You can reference the Nelson rules to support this.
