XbarS Charts from QI Macros in Excel
Purpose: Evaluate stability of processes using variable data--time, cost, length, weight The XbarS chart can help you evaluate the cycle time for almost any process: making a widget, answering a customer call, seating a customer, delivering a pizza, or servicing an appliance. This chart is especially useful when you do this many times a day. Collecting the data could be expensive if you measured every time you did it. Using a small sample (typically 10 or more), however, you can effectively measure and evaluate the process. Calculate, plot, and evaluate the standard deviation (S) chart first. If it is "out of control," so is the process. If the S chart looks okay, then calculate, plot, and evaluate the X chart. The XbarS chart is just one of the tools included in the QI Macros for Excel SPC Software for Excel.
