Exception Reporting

5967–9446 141

The Auto-adjusting baseline always uses the baseline statistic deﬁned in

the Targets/Statistics parameters screen. In other words, you cannot

change the baseline statistic on the Exception parameters screen.

For this option, specify what percentage of the data points in the graph

have to be outside (above or below) the low/high baseline envelope in

order for this graph to be deemed exceptional.

Note that there is a relationship between the baseline conﬁdence level

(speciﬁed in the Statistics/Targets parameters screen) and the value

entered for exception criteria.

For example, if auto-adjusting baseline exception criteria of 10% are

applied, the data for that reporting period has to fall outside the baseline

envelope for more than 10% for it to be considered to be an exception. If

the conﬁdence level is 90%, it means that 90% of past data (16 weeks

prior to the reporting period) is within the baseline envelope.

Select the type of exception

The available ﬁelds depend on

which exception type you

choose

You can choose Auto-

Adjusting Baseline only if the

baseline is conﬁgured in the

Statistics/Targets parameters

For Static Threshold,

select the statistic,

choose the direction

(above or below),

indicate the threshold

value, and set the

number of consecutive

threshold violations

Available statistics

depend on the

parameters
