The challenge

Corporate meeting

Field operations at telecom scale

The constraint: remote engineers lack real-time network visibility, complex multi-vendor equipment, lengthy resolution times

Telecommunications Operator faced an operations-driven constraint: maintaining network uptime SLAs with financial penalties required visibility into equipment health and rapid response procedures. Field engineers in remote locations lacked real-time access to network topology and equipment data.

The engagement demanded establishing tiered field support with L1/L2/L3 escalation, deploying mobile device management, implementing predictive maintenance using equipment telemetry, creating real-time SLA dashboards, and optimizing spare parts logistics..

Our approach

Tiered field support with predictive maintenance

Teceze designed and implemented tiered field services: L1/L2/L3 escalation with level-appropriate tools, mobile apps giving engineers real-time network topology, predictive maintenance analyzing telemetry to forecast failures, and SLA dashboards providing visibility to leadership.

From challenge to transformation, the solution included:

Tiered field support model (L1/L2/L3)

L1 frontline technicians with tablet access to network topology and basic troubleshooting. L2 senior engineers managing complex escalations. L3 vendor specialists for manufacturer-specific issues.

Mobile device management for engineer tablets

Managed tablets with offline mapping and documentation. Push-to-talk integration for team coordination. Remote wipe capability if device lost.

Predictive maintenance platform

ML models analyzing equipment telemetry (temperature, vibration, power consumption) to forecast degradation. Alerts triggered 72 hours before predicted failure.

Regional caching for model assets

Local caching of large design files reducing re-transmission. CDN delivery of frequently used libraries.

Governance and Reporting Cadence

Operational transparency and stakeholder alignment are critical to program success. A layered governance model keeps program health and costs visible:

Cadence Forum Focus
Daily Operations stand-up Open tickets, escalations, SLA status, regional issues, equipment failure alerts
Weekly Field ops review Deployment volume, resolution metrics, field engineer satisfaction, at-risk sites
Monthly Governance call Regional rollout status, predictive maintenance accuracy, cost tracking, spare parts optimization
Quarterly Business review Program health, SLA compliance, cost savings, 5G expansion roadmap, support partnerships
