Managing change in multi-vendor networks is becoming one of the most complex operational challenges facing telecom providers. Configuration inconsistencies across vendors, combined with manual processes and gaps in rollback procedures, continue to drive a significant share of outages. As networks evolve to include cloud, wireline and wireless domains, the problem is no longer isolated to individual devices or incidents, but instead tied to how change is coordinated and controlled across the entire environment.
This complexity is pushing configuration and change management beyond a single operational function and into the core of OSS. It plays a role in planning through standardized configurations, supports orchestration by translating intent into device-level execution, and remains critical in assurance where resolving issues often requires controlled updates. In multi-vendor environments, the ability to track and manage drift becomes essential to maintaining consistency as networks continuously change.
The challenge ultimately comes down to governance. Without a unified approach to managing configuration and change across vendors and layers, operators risk fragmentation, compliance issues and reduced visibility into network behavior. As change volumes increase, the ability to standardize and control how those changes are introduced becomes fundamental to maintaining stability, security and trust in increasingly dynamic networks.
