ODA providing value to CSPs and suppliers alike
Open Digital Architecture (ODA) is a standardized cloud-native enterprise architecture blueprint for all elements of the industry from Communication Service Providers (CSPs), through suppliers to system integrators. It accelerates the delivery of next-gen connectivity and beyond - unlocking agility, removing barriers to partnering, and accelerating concept-to-cash.
Introducing the future of software interoperability
ODA replaces traditional operations and business support systems (OSS/BSS) with a new approach to building software for the telecoms industry, opening a market for standardized, cloud-native software components, and enabling communication service providers and suppliers to invest in IT for new and differentiated services instead of maintenance and integration.
Find out more by going to the ODA interactive map to discover the architecture framework, a common language, design principles, and specifications for standardized, interoperable software components and Open APIs.
You can also find out more about the ODA components and Canvas and there is a masterclass on building blocks of ODA, the concept, the structure, and the business drivers for using ODA Components.

A global, living asset delivering real-world benefits
"ODA is very much aligned with the Salesforce approach and methodology of being open, following open standards, so it naturally fits with our common objectives and goals." Abhi Sur, Senior Director, Industry Solutions, Communications & Media - Salesforce
TM Forum's CEO Nik Willetts explained that the Open Digital Framework will create “a living framework – not paperwork, not standards, but a living framework for collaboration between companies, and it’s already being built today.
It’s crowdsourced and built through innovation, combining the right tools, the knowledge and the essential standards that are needed to transform our way of working to enable zero-touch partnering and zero-touch interoperability.”
