What’s OSS versus BSS?

AMKBCloud Fx Domains ModelOSS versus BSS, what’s the difference? The distinction between an Operational Support System (OSS) and a Business Support System (BSS) is historical. For over 100 years the monopoly telco business model was focused on maintaining exceptional operational quality on the network. Hence, the need for systems that would support operating the telco business, which was the network. In the TM Forum Frameworx Domains this would equate to the Resource Domain as well as the Resource-Facing segment of the Service Domain, as shown in the diagram.

Since divestiture the business model for a traditional telco has changed greatly and the need to be a competitive business has steadily shifted the focus toward Business Support Systems (BSS). As shown in the diagram, the realm of the BSS is everything outside of the historical OSS footprint; Market/Sales Domain, Product Domain, Customer Domain, Supplier/Partner Domain and the Customer-Facing segment of the Service Domain.

With the latest iteration of network/technology changes embodied in Software Defined Networks (SDN) and Network Function Virtualization (NFV) the shift in business focus to the BSS will accelerate as the ‘network’ transforms into a programmable distributed computing platform rather than the old configurable circuit switching network.

This will put more pressure on the communication service provider and their partners to deliver ever new product offerings for sale to the marketplace. These product offerings will mainly be composed from pre-defined product specifications. Product Specifications bind together the requisite Service Specifications and Resource Specifications to fully define the marketing and technical definitions of the new offering. This composite information is managed in the product catalog and used to support the end-to-end fulfillment processes; marketing, selling, ordering, provisioning, configuration & activation, and billing.

Once sold to the Customer, the Product must be managed and maintained per the terms & conditions of the sales agreement. When the Customer has a problem they must be able to contact their provider and be assured that the problem will be investigated and resolved. But, which provider to contact? The service provider? The hardware provider? The software provider?

As shown in the Fx Domains model the relationships between the Customer, sold Product Offering, operating Product, Service & Resource and Supplier/Partners must be managed and easily navigable in order to support the Assurance and Billing end-to-end processes with high quality customer care.

Central to being able to manage the requisite information and relationships is the Product Domain. The importance of which will only increase as the move from OSS to BSS accelerates over the coming months and years.
