Cumulative sum control charts and moving average control charts also detect small shifts more quickly than an ordinary Shewhart chart. See Part 2, "The CUSUM Procedure," and Part 5, "The MACONTROL Procedure."

The data set ASSEMBLY is also used by subsequent examples in this chapter.
If the TESTNMETHOD= option were omitted in this example, the tests would not be applied, and a warning message would be displayed in the SAS log.
If two or more tests are positive at a particular point, the default label identifies the index of the test that was specified first with the TESTS= option.
