Cerillion Blog - Digital Transformation

In 1995, two futurologists made a series of projections for the state of telecoms in the 2020s. We revisit their forecasts in 2025 to see how well – or not – their predictions held up.

TM Forum’s Open Digital Architecture (ODA) provides telcos with a blueprint for replacing legacy systems with a modular, cloud-native approach. Leonardo Hodgson considers how ODA Components are creating agile, interoperable digital ecosystems, and why they matter.

Headless BSS allows telcos to retain their existing customer-facing platforms, while modernising and integrating back-end functions, giving operators the flexibility to choose only the components they need, and benefitting from streamlined, pre-integrated deployment.

Digital transformation in the telecoms sector has proven to be a major challenge, with many CSPs having so far failed to realise its full potential. Can telcos revitalise their efforts, or are they doomed to over-promise and under-deliver?

What happens to the telecoms industry if mobile networks reach overcapacity and data traffic starts to fall? We might already be in that situation. Has cratering data traffic growth brought us to "the end of telecoms history?"

This year’s DTW25 – Ignite event showcased some of the many innovative Catalyst projects being headed up by TM Forum and its partners. Fresh from presenting his own work on the showfloor, Cerillion Product Manager Leonardo Hodgson reflects on this year’s event, and its stand-out projects.

How can CSPs overcome the limitations of monolithic legacy IT systems and embrace a cloud-native, modular future? Dominic Smith explores how composable BSS/OSS solutions are helping telcos to launch innovative new services and unlock new revenue opportunities.

Cerillion’s first Product Forum of 2025 offered our customers a look-ahead to the new features coming in our next product release and set out the roadmap for further updates during the year ahead.
