Order Management (COM/SOM/ROM)

What order management means in telco and why the three-layer model (COM/SOM/ROM) exists.

How commercial orders are captured, validated, and managed from CPQ through to fulfilment.

What SOM is, where it sits between COM and ROM, and how a product order becomes a service order.

How SOM turns CFS into technology-specific RFS, resolves dependencies, builds the orchestration plan and moves the order through its TMF641 states.

Fallout and failure handling, keeping service inventory true, the systems SOM talks to, and process- versus rule-driven SOM.

How service orders decompose into resource orders for network activation.

How SOM integrates with technology domains — direct API to platforms (Mobile Core, RAN, Service Platforms) and ROM/NSO for device configuration (Transport, IP Core). Catalog-driven routing with per-domain engine mapping.

Why SLM — not just Product Inventory — is the single runtime truth of what each customer has, how it bridges COM, SOM, and billing, and what breaks when it is missing or misused.

The BSS runtime record of what each customer bought: product instances, their characteristics, lifecycle states and billing links, and the TMF637 API that exposes them.

The OSS runtime record of the CFS and RFS instances that deliver each product: how it links product to resource, feeds qualification and assurance, and diverges from Product Inventory.

How BPMN 2.0 workflow engines drive order orchestration — separating process logic from code, enabling visual process design, and providing structured compensation and jeopardy management.

How catalog-driven architectures create structural data lineage — linking every entity from customer order through to network activation — and what breaks when links are missing.

Interactive simulation showing how an end-to-end order flows through the BSS/OSS stack — from CRM lead capture through to billing activation and service assurance.
