How to do root cause analysis of KPI's

Wallis Dudhnath - 22nd May 2018  (09:15 GMT)

There are now several Expert Analytics Tools that can be used to provide information to key customer stakeholders: Managed Services, Service Operation Centre, Network Operations Centre, etc.. Information is collected from Probes, Signalling / Control planes, 3GPP OCS, CRM, Handset information, etc..

The Expert Analytics tool will aggregate and correlate the information from a near realtime Data Lake (Big / Fresh Data reservoir) and present the information as a set of easy to read graphs.

Fits into the wider topic of Customer Experience Management.

Any one can do or show us basic analysis for one of main KPI's that he know it very well

Hello ALi!

for sure, it's quite tough to go through each of these KPis.
However, the best way of having them right for analysis and optim is to identify where each KPI takes its source (counters being pegged in call flow)
From there, you'll have many facilities in addressing them
