percent signs, currency symbols, and so forth. Negative numbers can be displayed
with negative signs or in parentheses. The value of zero can be shown using any
string entered, such as a dash or N/A. Finally, a tool tip can be added to the KPI
so that anyone hovering their mouse over the KPI will see a tool tip pop up with
additional information.
The next column is Thresholds and it is only available for the Target, not the
Actual. Thresholds are the points at which indicators change from one state to
another. A three-position indicator will have four values: Best, Threshold 2,
Threshold 1, and Worst. Indicators with ten positions will have eleven values, and
so forth. It might seem strange for Thresholds to have Best and Worst, but these
come into play when creating a composite score that can be rolled up. For example,
assume that the KPI is sales. If the target is $1 million, then any sales over that value
are probably good, or green in a standard three position, green/yellow/red indicator.
However, what is the ???best??? possible value for sales? Theoretically, there is no
maximum. Sales could be $10 million, $100 million, or more. Therefore, at some
point, a percentage of the target is usually listed as the maximum, and the default in
PerformancePoint Server is normally 120%. This means that if one group hits 120%
of their sales target and another group hits 140% of their sales target, both get the
same ???score??? for that KPI; in other words, they??™ve both achieved the best the system
will consider.
