Appendix U12 UMTS Network KPI
NOTES: This document can be used as an example of defining KPIs in a contract. It is in Ericsson’s interest that KPIs are well defined, including: a
KPI target values (keep as few with targets as possible)
b
Formula and measurement definitions (for drives and stats)
c
Where and how KPI will be measured (locations, setup, tools, drive, statistics)
d
Conditions – prerequisites, exclusions
e
Statistical considerations
As much of this as practical should be defined in the contract, particularly anything that will limit Ericsson’s risks and costs. Some of the material in this document may best be included in other parts of the contract, including the Acceptance Procedure and associated documents. KPI target values have very little meaning until the conditions of measurement are defined as above. Committing to a target without defining how, when and where it will be measured leaves Ericsson at great risk. N.B. The KPIs and their targets included in this document may not be the ones recommended by Ericsson. Refer to the KPI Technical Guidelines and KPI data base for current recommendations.
