What is "setup control chart"?

Hi All,

On page 34, the SPC manual (2nd edition) states:

The purpose of the Improvement Cycle is to gain an understanding of the process and its variability to improve its performance. As this understanding matures, the need for continual monitoring of product variables may become less – especially in processes where documented analysis shows that the dominant source of variation are more efficiently and effectively controlled by other approaches. For example: in processes where maintenance is the dominant source of variation, the process is best controlled by preventive and predictive maintenance; for processes where process setup is the dominant source of variation, the process is best controlled by setup control charts.

I think "setup control chart" should be a usual chart such as Xbar-R or I-MR which is applied for setup operation/parts.
Is it right?

Thanks all

I would agree. While I have not heard of that specific term, the intent is clear. The rationale would be that the chart would confirm whether the setup was within the bounds of common cause variation.
