What is a Key Performance Indicator

Key performance indicatorKey performance indicator!KPI" is a function ofcounters. In its simplest form# KPI is an

individual counter.

The idea $ehind the KPI concept is that the

information of one counter value is rarely

enough. %n the other hand# the operator needsto get information on networ& performance in a

compact format# in order to minimise human

analysis effort.

With carefully defined KPIs# the operator caneasily see the overall status of networ&

performance# e.g. how RR' or RA( setups

succeed# is the RA( drop ratio on an accepta$le

level# are there severe pro$lems in handovers#

and many other criticities.
