De-risk Your Transformation

Cerillion’s expert implementation and integration services will take the risk out of your BSS/OSS transformation and help you achieve a smooth go-live.

Cerillion has an impressive track record of successful project deliveries over the past 20 years. The foundation for this success is the Cerillion Implementation Methodology, which is built on a heritage of Systems Integration projects tempered with pragmatism based on experience of successful BSS/OSS solution implementations.

One of the major critical success factors in any implementation is maximising understanding between Cerillion and our Clients. To be successful this is maintained throughout the project lifecycle through frequent reviews and open, honest communications. Success is therefore linked not only to a structured project approach, but also detailed workshops with Clients early in the project to maximise mutual understanding.

Initial workshops focus on requirements analysis, infrastructure and installation analysis, migration strategy (if applicable), configuration and interface details, with all the information collated into a number of detailed plans and requirements documents which drive the overall implementation.


Cerillion has a wealth of experience in migration projects including big bang replacements, phased migrations, and converging from multiple separate systems into a single Cerillion solution. This experience has enabled us to build up a robust set of tools and processes to manage this mission critical service. Our proven methodology tackles all major migration challenges including business processes and staff training, systems integration, and of course the data migration itself.

Certainty of outcome

The successful delivery, on-time and on-budget, of such a complex BSS transformation project is a fantastic achievement by Cerillion and my team at Sure. I couldn’t be more pleased with the outcome.

Previously, our delivery of MVNO projects was constrained by our charging system provider; now, with Cerillion, we are empowered to manage the complete platform ourselves, making it much easier for us to launch new MVNOs. With Cerillion as our trusted partner, our portfolio of MVNOs in South Africa is growing rapidly, and I am excited by the opportunities we have to expand into new markets across the region.
