It descript process performance by dpmo (defects per million opportunities) Process variation: type i error (a ) : reject h0 when h0 is true, type ii error (b. If support ha (i. e. process is out of control), stop process and correct the problems. is the level of significance of test of hypothesis: rejecting h0 at a, rejecting h0 at a. = 1% test is highly significance: use 3s control limits or 1s control limits is depend on situation or significance, so either control has narrower limit than 3s one is correct.
