This will help figure out if the process is stable and accomplishing as meant or requires corrective action.
Reply to Paul 6 yrs back It would be achievable to accomplish the calculations While there is no such factor as specific I don't Consider. Simply because you evaluate 1000s of factors doesn't suggest that the process is secure.

“The positioning’s alert and action degrees may be tighter than Individuals suggested in Annex one dependant on historical information, and may be the result of affordable functionality evaluation soon after periodic and typical evaluation of the data”.
