We review the long-established rational subgrouping principle for determining an effective sampling plan for process monitoring. We present some other general advice that has been given in the literature and discuss some issues related to sampling as it applies to monitoring. Because it is very common to form samples by aggregating data over fixed time intervals, we review the literature on the effect of temporal aggregation on process monitoring performance and provide our perspective. We offer some practical advice and some directions for future research.
