A new graphical tool, called a multi-process performance analysis chart, can be used in a quality control method for analyzing the performance of a group of processes in a multi-process environment. The method achieves at least three objectives. One, the method is useful for aggregating on one chart the overall status of a group of processes. Departures of process mean values from target values are readily interpreted from the chart as are process variabilities and process capability indices. Estimates of the expected fallout of a process parameter with respect to its tolerance are also readily generated. Two, the method allows for prioritizing quality improvement efforts in complex operations, which may comprise many processes. And three, the method allows for quantifying improvements resulting from reductions in the departures of process means from target values and from reductions in process variabilities.
