The three-year agreement, estimated to be worth more than $200 million, will see the company supply consulting services, integration, application support services and software.
It will also provide a range of applications based on its Service Provider Delivery Environment (SPDE).
The project also involves other sub-contractors and a range of software providers, and covers five core business and operational support systems components including fulfilment, assurance, resource management, billing and integration, and B2B.
Implementation work has already begun and will be completed in four stages.
The project will enable NBN Co to manage its network, provision and configure services, and bill its wholesale customers.
The new system is set to provide retail service providers with ability to order new services, report faults, perform service qualification checks via business-to-business interfaces or through portals that will allow transparent and flexible management of their own services on the National Broadband Network (NBN).
NBN Co CIO, Claire Rawlins, said a key factor in choosing IBM was due to its track record of managing complex and mission critical programs.
“The project will focus on both process optimisation and automation,” Rawlins said.
NBN Co head of network operations, Steve Christian, said in order for service providers to effectively resell their products and services, it needed to install a robust and highly-automated system with self-management capabilities.
“We will be carrying out this project by means of an integrated team of experienced providers all working together to achieve real end-to-end business outcomes,” Christian said.
