| Step | Action | Description | | :--- | :--- | :--- | | | Collect Data | Gather 20-25 subgroups of 3-5 samples each from your process, ensuring it's stable (no known changes or adjustments). | | 2 | Calculate Statistics | For each subgroup, compute the mean ( X̄ ) and the range ( R = max - min ). | | 3 | Compute Overall Averages | Calculate the overall mean ( X̄-double bar ) as the average of all subgroup means, and the average range ( R̄ ) as the average of all subgroup ranges. | | 4 | Determine Control Limits | Locate control chart constants ( A₂ , D₃ , D₄ ) from a standard table based on subgroup size ( n ). Then calculate UCL and LCL. | | 5 | Plot the Charts | Create two charts: one for X̄ and one for R. Plot the data points, centerlines, and control limits, then connect the points with lines for visual analysis. | | 6 | Interpret the Results | Examine the charts for any out-of-control points (beyond limits) or non-random patterns (e.g., 8 points on one side of the centerline). | | 7 | Investigate and Act | Investigate any out-of-control signals, identify root causes, and implement corrective actions if a special cause is found. Remove the affected subgroups and recalculate limits for an updated baseline. |
