Telecoms operators need to launch services faster, reduce operating complexity and improve customer experience. Many are still held back by legacy business support systems and operational support systems that are costly to maintain and difficult to change.
Cerillion presents composable BSS/OSS as a practical way to modernise these environments without replacing everything at once.
A composable architecture breaks large systems into modular components that can be added, changed or replaced as business needs evolve. This gives operators more control over the timing and scope of transformation, while reducing the risk of a single, large-scale implementation.
At an industry level, the TM Forum’s Open Digital Architecture supports this model through common standards, interfaces and deployment principles. Standardised application programming interfaces can make it easier to connect systems from different suppliers and reduce the need for extensive bespoke integration.
Traditional telecoms platforms are often tightly linked to one vendor or heavily customised over time. That can make upgrades slower, increase maintenance costs and limit the ability to introduce new products.
A composable approach gives operators more flexibility to select the systems they need and introduce new capabilities in stages. It can also reduce supplier dependency and improve the ability to respond to changing market conditions.
Cerillion also argues that transformation should be driven by commercial outcomes rather than architecture alone. The objective is to shorten product launch times, lower operating costs and create a more adaptable platform.
