Case study: Reinvention runs on billing, whether you like it or not
- Why modern billing has become a strategic enabler of innovation, efficiency and business growth
- Accelerating service launches and reducing operational complexity through automation and agentic AI
- Improving customer experience through greater accuracy, transparency and personalization
- Lowering cost-to-serve while increasing agility across products, services and business models
- Strengthening customer loyalty and long-term value through next-generation billing platforms
Mirit Ashkenazi, Product Marketing Director, Amdocs
14:30 - 14:45
Case study: How TalkTalk Business delivered a cloud-first billing transformation
- How TalkTalk Business rebuilt its operational foundation under the pressure of a full company spin-off and why doing so at speed was non-negotiable.
- How adopting Aria Billing Cloud enabled TalkTalk Business to move toward a composable IT architecture, embracing a Cloud SaaS model aligned with TM Forum's Open Digital Architecture (ODA) rather than replicating legacy systems
- What it really takes to deliver cloud-native billing at pace and how partnering with Aria Systems, Salesforce and Virtusa helped making execution at speed a reality
- The lessons learned that every operator considering a transformation of this magnitude needs to hear
Brendan O’Brien, Co-founder and Chief Innovation Officer, Aria Systems

Panel: Migrating from monolith to modular – de-risking the journey and accelerating value
- How are you managing the cost and complexity of running legacy and composable stacks in parallel — and where does ROI most often get delayed or diluted?
- In a best-of-breed ecosystem, how do you stop integration layers from becoming a bigger cost and risk than the monolith they were meant to replace?
- Which business domains have delivered the fastest and most sustainable speed-to-value once decoupled — and which turned out to be harder than expected?
- When an end-to-end service fails across a multi-vendor composable architecture, how do you design accountability without reverting to a single-vendor comfort zone?
- What organizational or cultural change proved most critical to de-risking a multi-year migration — and what did you underestimate?
