  Key Concepts: 
  A mean-value chart is a statistical tool used in Quality Management (QM) within SAP. It is used to monitor the stability of a process over time by plotting the average value of a process variable against the number of samples taken. The mean-value chart can be used to detect any changes in the process that may indicate a need for corrective action. 
  
  How to use it: 
  The mean-value chart is created by plotting the average value of a process variable against the number of samples taken. The chart can be used to detect any changes in the process that may indicate a need for corrective action. The chart can also be used to compare different processes or different products within the same process.

  When creating a mean-value chart, it is important to ensure that the data points are evenly spaced and that the sample size is large enough to provide an accurate representation of the process. Additionally, it is important to ensure that any outliers are removed from the data set before creating the chart.
