Product Benchmarks Report (DPMO versus Z.Bench)main topic
Product Benchmarks Report (DPMO versus Z.Bench)Displays a graphical view of the benchmark statistics for the collection of components that are in the product report.
DPMO is a measure of long-term performance, while Z.Bench ST is a measure of short-term performance.
The locations of the clusters of points represent where the capabilities of your processes tend to be concentrated. In the example above, there is a cluster just below 4 on the Z.ST scale, and another near 4.5. Thus, many of the processes used here run from just under 4 to just over 4 sigma. This is quite typical.
