Ruleset 1— Based on the test's values recorded at the flfth additional run. If the process has shifted to a higher defect ratę, the test values at the end of the flfth additional run should indicate higher values than the initial firing.

Rule 1 - If CUSUMm(+5)	<0.5	==> False alarm	[17]
Rule2~IfSPRTmf+5)	<0.25	==> False alarm	[18]
Rule 3 - If EWMAm(+5)	<0.2	==> False alarm	[19]
Rule 4 — If GCCf+5)	>9.0	==> False alarm	[20]
Rule 5 - If CUSUMm(+5)	> 1.5	==> Detection	[21]
Rule 6- If SPRTm(+5)	> 1.0	==> Detection	[22]
Rule 7 - IfEWMAm(+5)	>0.85	==> Detection	123]
Rule 8 - If GCCH-5)	<1.635	==> Detection	[24]

Ruleset 2-Based on the number of test firings during the additional five runs. If the process has shifted to a higher defect ratę, the leadtest and the backup tests should fire morę often than for a false alarm.

Notes: CUSUM2 denotes the second CUSUM with h| = 3.5, and the sum of # fires is the sum of all test (excluding lead CUSUM) firings during additional runs.

Rule 9 •	- If # CUSUM fires	= 5	==> Detection	[25]
Rule 10	- If # CUSUM2 fires	>3	==> Detection	[26]
Rule 11	- If # EWMA fires	>0	==> Detection	[27]
Rule 12	— If Sum of # fires	>4	==> Detection	[28]

Rule 13 -- If CUSUM2 (+5) fires

==> Detection
