Executive summary
Telecom legacy estates often sit between network systems, subscriber records, product catalogs, mediation feeds, billing cycles, tax logic, partner settlement, and customer care. The hard part is proving how service states and usage charges stay synchronized.
COBOLpro builds a domain brief that makes OSS/BSS dependencies visible before product launches, billing migrations, network updates, or vendor replacement.
Legacy systems in scope
The source estate to turn into an operating map.
Each row is structured for executive review: where the COBOL behavior sits, what it touches, and what the documentation must prove.
Subscriber and service operations
Legacy estate
Subscriber, order, service catalog, provisioning, activation, number management, device, and network inventory systems
Documentation focus
Service qualification, activation states, plan changes, inventory updates, and network handoffs
Mediation, rating, and billing
Legacy estate
Usage mediation, CDR processing, rating, taxation, discounts, billing, invoicing, collections, and dispute systems
Documentation focus
Usage transformations, pricing rules, tax calculations, invoice generation, credits, and adjustments
Partner and regulated interfaces
Legacy estate
Wholesale, roaming, partner settlement, finance, customer care, SLA, regulatory, and tax feeds
Documentation focus
Partner reconciliation, regulated billing evidence, dispute handling, and downstream reporting
Operational workflows
Business capabilities, not raw program lists.
COBOLpro groups source behavior around the operating workflows buyers need to preserve, explain, or replace.
01
Order and network operations
- Order capture, service qualification, provisioning, and activation
- Plan changes, device changes, and service state updates
- Network inventory, trouble tickets, SLA reporting, and handoffs
02
Usage and billing operations
- Usage mediation, rating, taxation, and invoice generation
- Credits, discounts, adjustments, collections, and disputes
- Billing cycles, customer care, churn, and retention support
03
Partner and finance operations
- Roaming, wholesale, partner settlement, and reconciliation
- Regulatory, tax, finance, and audit reporting
- Product launch and catalog update dependencies
Risk and control priorities
Where legacy ambiguity becomes business exposure.
The assessment narrows risk to business impact and source-backed control evidence instead of treating documentation as a generic code inventory.
01
Usage reconciliation
Business impact
Rating, mediation, and billing defects can create revenue leakage, customer disputes, and regulatory exposure.
Control focus
Trace usage records from network events through mediation, rating, invoice, tax, and finance outputs.
02
State synchronization
Business impact
Subscriber, service, catalog, and network states can diverge across OSS, BSS, vendors, and care systems.
Control focus
Map service state transitions, file timing, transaction handoffs, and recovery paths.
03
Partner dependency
Business impact
Wholesale, roaming, tax, and partner interfaces can block billing or network documentation.
Control focus
Inventory partner feeds and settle each dependency against source programs, jobs, and reconciliation controls.
COBOLpro assessment output
Concrete artifacts for continuity decisions.
Outputs are written for shared use across business, audit, architecture, application, data, and delivery teams.
01
Provisioning and subscriber lineage
Order, service qualification, activation, inventory, subscriber, and network handoffs tied to source.
02
Usage and billing rule catalog
Plans, usage, rating, taxes, discounts, credits, adjustments, disputes, and exceptions in buyer-readable form.
03
OSS/BSS interface inventory
Network, customer-care, partner, wholesale, roaming, finance, regulatory, and tax feeds organized by workflow.
04
Launch and migration impact package
Evidence for product launches, billing migration, network documentation, and partner changes.
