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

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?
