When Network Change Became a Data Problem (Not a Process One) RAN · Change Management · Cloud Analytics · 7 min read Network change management used to fail quietly. Not because engineers didn't know what they were doing — but because the system around them wasn't designed for scale. Email threads, spreadsheets, and manual verification worked when change velocity was low. Once cloud-native cores, multi-vendor RANs, and frequent parameter tuning became normal, that model collapsed under its own weight. The problem wasn't the number of changes. It was the lack of context. Engineers knew what changed. Not always why, what else it touched, or whether the outcome matched the intent. What the old model actually broke The failure mode was not dramatic. Changes executed correctly. Parameters landed where they were supposed to. The breakdown was in what came after: no queryable record of what state the network was in before, no automatic comparison of what change...
