Engagements that start with aligned field definitions finish on schedule. Those that begin with a vague "send us your subscriber data" request stall in week three when billing and CRM teams disagree on activation timestamps.
Minimum extract fields
- Line activation date and current status
- Plan ID mapped to a catalog export (not display names alone)
- Disconnect reason codes as recorded in source systems
- Monthly billed revenue and payment failure flags
- MNP-in and MNP-out dates where applicable
Internal stakeholders to involve early
Billing operations owns field accuracy. Network planning validates geographic roll-ups. Legal reviews the data transfer agreement. Scheduling a single scoping call with all three saves rework later.
Realistic calendar
Allow six to eight weeks from signed scope to final briefing. Quarter-close periods in Korean operators often delay extract availability — we recommend initiating data requests two weeks before fiscal quarter end.
