Box-and-whisker charts are particularly useful for viewing multiple process streams. This capability can be especially useful in industries such as food packaging and beverage bottling, where minimum fill volumes and weights are typically regulated—and where overfill can significantly cost manufacturers.
In such environments, this chart will quickly reveal vital details:
- Whether products are being filled to minimum required levels
- What the average fill volume is
- Where fills are exceeding required volumes or weights
With the box-and-whisker chart, you can easily compare processes or products to discover variances and determine outliers—which present problems and opportunities for improvement.
Plus, you can examine in-spec data to find savings you might never have expected.
