The last few years reinforced the fundamental role that the telecommunications sector plays in connecting governments, communities and businesses – big and small – across the world. Whether it is the provision of mission-critical social services, the exchange of information, manufacturing, working from home and business continuity, there is no doubt that the telecommunications sector played and continues to play a vital part of advancing the global economy and society.

Governments, business and individuals now look to the sector for ongoing agility and expect a similar pace in innovation.

The industry at a crossroads – continue as traditional BSS/OSS or embrace new heights of agility

With the arrival of the internet and Cloud, disruption to the sector was considerable. Telecommunications players needed to rapidly embrace IT agility in ways like they had never before, with new players entering the sector and those that didn’t keep up fading away.

Today, with the advent of 5G, the Internet of Things, AI, autonomous networks, smart cities, open digital architectures, as well as connected mobility and a move towards cloud-native models and AI at scale, the role of communications services providers (CSPs) is once again at a crossroads and being rapidly redefined.

Yet rather than view this as a risk, CSPs that look upon these rapidly shifting sands as an opportunity are poised to play a pivotal role in the near future. They are embracing a far more agile approach to building software for the telecommunications industry, turning away from traditional operations and business support systems (OSS/BSS), and opening a market for standardised, cloud-native software components.

Enter Open Digital Architecture (ODA).

Accelerating next-generation connectivity

In this phase of the digital era, CSPs are under increasing demands to create products and services more rapidly and in a cost-effective way than ever before. What has emerged as a solution to ensuring long-term business agility, through the seamless interconnection of products, is ODA. This is a standardised cloud-native enterprise architecture blueprint for CSPs, vendors and system integrators to help accelerate the delivery of next-generation connectivity.

In this next wave of commerce, CSPs will need to rapidly construct and deliver new digital enterprise-grade services for communities and business ecosystems alike – quicker than ever before, in real-time and in a cost-optimised fashion. The adoption of ODA greatly helps in addressing these complex challenges.

Embracing ODA provides strategic blueprint for radically altered operational approach

All too often, when any kind of disruption or transformation materialises, the fear is that the technology investment will be aggressive. And many parties have been known to dive in without taking a strategic and holistic approach to such shifts.

We believe that wise CSPs will develop a holistic strategy to diversify their business and radically alter their operational approach. What ODA provides, when approached correctly, is the blueprint that not just CSPs but also their suppliers and SIs need to change their IT and network systems. Investing upfront in the strategy helps fast-track the creation of new and differentiated services that will improve productivity, reduce maintenance and integration costs, whilst enhancing the customer experience. In essence, this is your key to modernising your underlying infrastructure and automating your operation.

Is ODA ready for CSPs today?

TM Forum, along with a range of companies, have been working together to create this industry standard and to advance ODA’s evolution to a point where CSPs are now leveraging it.

We are proud to have been both leading and actively working in groups as a member of TM Forum to help the sector reach this point. Specifically, and next to be released into the mix, will be ODA Components and the ODA Canvas.

To unpack this, think of ODA Components as the reusable building blocks which can be used to build business solutions. They interoperate using TM Forum Open APIs and share a common data model, making simplified interoperability a reality. Components run inside the ODA Canvas, which exposes a standard set of services to all components, covering functionality such as observability, management and security. Components from multiple vendors can interoperate seamlessly in a common or distributed Canvas, delivering simplified operations and reducing total cost of ownership.

In fact, at the recent edition of Digital Transformation World, held in June in Copenhagen, TM Forum announced an ODA Component conformance program, offering certification of vendor components.

Very quickly, you can see the importance of ODA, and the benefits to be realised by embracing this technology.

Are technology partners ready?

The early adopters are up and running, and ready to support. ODA increasingly meets the technical and strategic needs of today’s CSPs in their pursuit of highly agile commercial operations.

We believe ODA could very well form a blueprint for CSPs build the structures and ecosystems that will ignite growth in the telecommunications sector and help them at the crossroads they find themselves at today.

1. What does “modernise with precision” mean for Tier-1 telecom operators?

“Modernise with precision” describes a low-risk, targeted approach to BSS/OSS modernisation where operators upgrade only the parts of their digital stack that create the greatest impact. Instead of embarking on high-risk, multi-year full-stack replacements, Tier-1 telcos selectively introduce cloud-native BSS/OSS, API-driven telecom architecture, AI-ready data layers, and TMF-compliant BSS components.
This modular strategy reduces cost and disruption, allowing operators to strengthen areas such as product agility, order orchestration, customer experience, and operational efficiency while maintaining stability in core environments. It aligns directly with TM Forum’s Open Digital Architecture (ODA), which encourages a composable, interoperable, future-proof approach to telco transformation.

2. Why is time-to-market so important for telecom monetisation today?

Telecom monetisation increasingly depends on the ability to respond quickly to new commercial opportunities – from enterprise IoT solutions and digital services to 5G monetisation, wholesale partnerships, and B2B vertical offerings. In this environment, operators that can design, package, and activate new services in days rather than months gain a clear revenue advantage.
Legacy catalogues, rigid product hierarchies, and tightly coupled BSS architectures make rapid innovation difficult. Modern operators therefore prioritise catalog-driven architecture, agile/composable BSS, and cloud-native BSS capabilities to give business teams control over offer creation without relying on long IT delivery cycles. Faster launch cycles = faster monetisation.

 

3. What is slowing down product launch cycles for many telcos?

The primary obstacles are deeply entrenched in legacy architecture: hard-coded product models, outdated catalogues, nonstandard integrations, and heavy IT dependencies. These constraints slow down even minor product changes, creating friction between commercial teams and IT.
Modern telcos are replacing these bottlenecks with TMF-compliant BSS, cloud-native catalogues, API-driven BSS integrated via TMF Open APIs, and low/no-code configuration tools. These solutions allow product owners to create and test offers independently, ensuring the Digital BSS backbone supports true agility.

4. How can telecom operators reduce order fallout and manual intervention?

Order fallout typically stems from fragmented systems, inconsistent data models, and brittle custom integrations across BSS/OSS chains. When orchestration spans numerous legacy systems, even small discrepancies can cause orders to fail.
Operators can dramatically reduce fallout rates by adopting zero-touch service orchestration, modern order management modernisation, end-to-end automation, and a unified data model across their Digital OSS and Digital BSS layers. Cloud-native telecom systems and order orchestration for telecom remove reliance on manual rework, minimise delays, and improve service accuracy – all essential to delivering predictable customer experiences.

5. Why is accuracy so important for B2B and wholesale customer experience?

For enterprise and wholesale customers, trust is built on precision. A single misquote, incorrect configuration, or missed activation can lead to delays, SLA breaches, revenue disputes, and strained relationships. These segments rely on highly controlled, predictable fulfilment processes – particularly as operators expand into 5G edge services, network slicing, managed security, and outcome-based contracts.
Improving accuracy requires strengthening the underlying architecture – through modern CPQ for telecom, clean data models, cloud-native BSS/OSS, and robust API-driven telecom architecture. When quoting, ordering, provisioning, and billing are accurate, customer satisfaction increases naturally.

6. How does cloud, AI, and API-driven architecture support telecom modernisation?

Cloud-native platforms provide the scalability, flexibility, and deployment speed needed to support modern telecom services. AI introduces intelligence into operations, enabling predictive analytics, anomaly detection, and proactive assurance. APIs – especially TMF Open APIs – ensure new components integrate cleanly with legacy systems.
Together, AI-powered BSS/OSS, cloud-native architecture, and API-driven integration create a digital foundation that supports continuous innovation, reduces technical debt, and enables operators to deliver new services more efficiently. This trio is central to future-proofing the telco stack.

7. What is TM Forum’s Open Digital Architecture (ODA) and why does it matter?

TM Forum’s Open Digital Architecture (ODA) is an industry-standard framework designed to help telcos simplify, modularise, and modernise their BSS/OSS environments. ODA promotes interoperability, composability, and openness so operators can integrate new capabilities without heavy customisation or vendor lock-in.
For Tier-1 operators, ODA serves as a blueprint for transitioning from monolithic legacy stacks to cloud-native, API-driven, modular BSS/OSS infrastructure. By adopting ODA-aligned solutions, operators speed up integration, lower deployment risk, and reduce long-term operational cost.

8. How is Hansen involved in TM Forum and ODA?

Hansen aligns its architecture directly to TM Forum’s ODA principles and has contributed to the development of one of TM Forum’s recognised industry standards. This reinforces a commitment not just to following best practices, but to shaping them.
Hansen’s portfolio of cloud-native, AI-powered, API-driven Digital BSS/OSS modules is built on TMF Open APIs and composable design principles. This ensures seamless interoperability in multivendor environments and helps operators modernise safely and incrementally.

9. Can operators modernise their BSS/OSS without a full-stack replacement?

Yes – and in fact, most Tier-1 operators now prefer incremental transformation. Full-stack replacement is high risk, slow, and expensive. By contrast, modular modernisation allows operators to introduce new BSS/OSS capabilities – catalogues, orchestration layers, charging engines, customer management, monetisation components – without destabilising the existing ecosystem.
This approach reduces risk, accelerates value, and aligns with ODA’s principles of composability and openness. Operators can modernise at their own pace while still maintaining service continuity.

10. How does modular modernisation reduce risk?

Modular transformation focuses on improving specific parts of the architecture – such as product agility, order accuracy, unified data, or 5G monetisation – without changing everything at once. Each module is integrated, tested, and scaled independently, which reduces disruption and improves predictability.
It also allows operators to retire legacy systems gradually, reducing technical debt over time while still realising near-term efficiency and revenue gains. This is why agile/composable BSS is now the preferred model for Tier-1 telecom transformation.

11. What operational improvements can telcos expect from a unified data model?

A unified, AI-ready data model brings real-time visibility across commercial and operational processes, enabling faster decision-making and more reliable service execution. It also allows operators to detect issues earlier, automate root cause analysis, and reduce order fallout.
This consistent data foundation is essential for AI-powered BSS/OSS, predictive assurance, next-best-action recommendations, and advanced analytics. It ultimately improves operational efficiency, accuracy, and customer experience – three core pillars of modern telecom performance.

12. Why is Customer Experience (CX) tightly linked to operational excellence?

Most customer experience problems – delays, incorrect orders, billing errors, missed SLAs – originate from inefficiencies within the internal BSS/OSS engine. When operators modernise their Digital BSS/OSS processes, eliminate manual workarounds, and ensure accurate orchestration and service activation, the customer experience improves naturally.
This is particularly true for enterprise and wholesale customers, where CX is defined by precision, predictability, and contract performance. Improving CX requires improving the processes beneath it.

13. How do Hansen’s solutions fit into a Tier-1 telco transformation strategy?

Hansen provides cloud-native, API-driven, TMF-compliant, AI-powered Digital BSS/OSS modules that integrate smoothly into hybrid and legacy environments. Operators can use them to strengthen catalog agility, automate order flows, unify data, enhance monetisation, or improve service reliability – without needing to replace their entire BSS/OSS stack.
This flexibility supports transformation at the operator’s own pace, aligned to business priorities, regulatory requirements, and commercial objectives.

14. What benefits can operators expect from a layered or hybrid modernisation approach?

A layered or hybrid approach allows operators to combine existing systems with cloud-native components, enabling transformation without disruption. Key benefits include:
• Faster time-to-market for new offers
• Improved order accuracy and reduced fallout
• Lower cost-to-serve through automation
• Stronger customer experience
• Gradual reduction of technical debt
• Alignment with ODA and modular architecture principles
This approach balances stability with innovation – ideal for Tier-1 operators.

15. How do industry standards such as ODA accelerate telecom digital transformation?

Industry standards like TM Forum ODA and TMF Open APIs reduce integration complexity, promote interoperability, and give operators a trusted blueprint for modernisation. They ensure that new BSS/OSS components can plug into existing environments without custom engineering.
By reducing dependence on bespoke integrations and enabling modular deployment, standards significantly lower long-term cost and accelerate transformation across the business. They also future proof the architecture for new technologies, including AI, automation, and 5G service innovation.
