Innovis Approach

Improved quality of delivery by Vendor Governance

NW performance improvement by Steering NW Optimization

Regular review to improve Database Consistency

Vendor Management

  • Innovis program management regularly audited the quarterly reports of vendors and ensured target KPIs are met.
    Implemented new KPI formulas and NW performance measurement is standardized for vendors.
  • City level KPI dashboard publishing for all tier 1 cities. This helps MPT to monitor the NW performance at city level.
  • Standardization of quarterly reports in line with MPT requirements was done.
  • Worst cells + KPI target not meeting cell identification.
  • Supported for closure of VIP customer complaints + weekly HVC complaints.
  • High number of complaint TSP/sites identified and shared to the MPT & vendors. Further optimization actions started for health check-up and optimization.
Achievement
  • Report rejection rate reduced by 30%
  • Overall CS traffic (Erl) is improved by 4.8% and PS traffic (GB) improved by 4.73%
  • Worst cells optimization was performed
  • Customer complaint closure and improved customer experience

Network Optimization

  • Steered network KPIs optimization
  • OSS KPIs health check, VSAT sites bandwidth up-gradation KPI governance
  • Identification for removal of extra power license-UMTS
  • LTE low throughput cell optimization
  • Border city optimization, border city GU re-farming
Achievement
  • Significant improvement in KPIs
  • GSM – CS-CSSR improved, TCH drop rate improved, SDCCH drop rate improved
  • UMTS – CS-CSSR improved, PS-CSSR improved, CS drop call rate improved
  • LTE – IFHO success rate improved from 96.3 % to 98.3%

Data Consistency
