Process monitoring is an important part of Operations Management (OM). Xbar charts are used to detect changes in the process mean. Recently, researchers proposed control limits adjustments to guarantee the chart’s desired in-control performance when parameters are estimated. We analyze the effect of these adjustments on its out-of-control performance. Recommendations are provided.
