SPC software Performance Charts
A GainSeeker® Performance Chart breaks down a process by traceability values (by “Machine” in the following chart example) using a Box and Whisker format. Managers can use this tool to visually compare data groups by mean and variation, zoning in on a particular operator or machine, for example.
Compare data groups
With a glance at the chart below, they can see that variation is greater in machine 1250 while the mean of 1400 is lower than the other two machines. This allows for quick visual comparison of data groups by mean and variation.
