Shaping both connectivity and the customer experience

At Telenor, we achieved something remarkable - we moved from on-premises to Google Cloud in 11 months, saving millions whilst building for scale. The learnings? Boring is good. You need to build a solid foundation to be able to scale and innovate. Speed is paramount. Excessive risk aversion can hinder progress and diminish value in the long run. Data needs to be democratized. Data accessibility translates into speed and usability.

Telecom companies have been at the forefront of innovation since the days of the very first switchboards, bringing people together over vast distances and providing instant access to global information. Today, they provide much of the infrastructure behind the intelligent systems powering our modern world, playing a crucial role not only in how we communicate, but also how societies operate and evolve. 

Founded in Norway in the mid-19th century, the telecommunications company Telenor Norway has been around to witness — if not drive — much of that transformation. "Over the last few years, we've undertaken a significant modernization, renovating technologies that are over 150 years old," says Åge Ingierd, Head of Analytics at Telenor. "But we're not just focusing on infrastructure: We're also shifting a significant portion of our investments to offering our clients more value-added services." In order to enhance customer experience, support new product development, and simplify operations, Telenor needed to gain greater control over its data — something its legacy platform wasn't enabling it to do. In November 2023, the company kicked off the migration of its on-premise data warehouse, audience management system, analytics dashboards, and customer call analysis tools to Google Cloud.

 The first phase of the process was completed in just 11 months, paving the way for advanced predictive modeling, deeper customer insights, and personalized, AI-driven interactions across multiple channels.

"By sitting down and reviewing everything Google Cloud had to offer, it became clear it was the best platform to support our goals," Ingierd says.

From on-prem to cloud-based in just 11 months

There was a major incentive to complete the first major phase of the migration as soon as possible: Telenor's existing contract for its legacy system was set to expire a few months later, and renewing the contract would have locked the company into a costly subscription model for several more years. "The flexibility of Google Cloud was a huge advantage," says Ingierd. "With our old platform, we essentially bought all the available software in advance but didn't use much of it. Google's pay-as-you-go pricing model allows us to add the functionality we need as we go along."

"A lot of our old infrastructure was on-premise software, including our data warehouse," he explains. "Each morning, we transported large amounts of data from the on-premise solutions into cloud-specific formats to view dashboards and reports. Maintaining all that took significant time and resources." Not only was on-premise data storage leading to inefficiencies and high maintenance costs, it was making it difficult to track real-time performance. "Our sales reporting was nearly 24 hours old each morning. For specific needs, like tracking net sales of specific products in real time, we had to create special solutions. These processes didn't align with our broader sales reporting system and resulted in duplicate solutions." Ingierd's team was also spending a significant amount of time copying data between solutions. 

The company's vision was to create a smarter, future-proof data warehouse solution where each domain takes responsibility for its data. "We brought the team together to look at our architectural requirements, and collaborated extensively with Google specialists to map out how we could set this up," Ingierd says. "The focus was to move forward gradually, starting with a confined area, which we could then build upon and adapt as we progressed." This approach enabled the team to test and refine processes before scaling them across the organization, adapting strategies in real time and ensuring minimal disruption to ongoing operations while building a foundation for the broader migration.

Empowering teams through enhanced collaboration and self-service analytics

This decentralization of analytics has been a huge success, and feedback on Looker and the new tools has been very positive. Dynamic filtering and the ease of building dashboards and reports have made the tools much more accessible to non-technical users.

The team kicked off the process by copying existing data into BigQuery to ensure continuity while preparing for the shift. Dataform was used to organize and transform the data, while existing dashboards and reporting systems were recreated in Looker. Throughout the process, teams worked in parallel to minimize disruption, and legacy systems were kept running to validate the accuracy of the new data. This ensured that business users could rely on consistent insights as the migration progressed.

The new platform integrates multiple Google Cloud products to provide Telenor with real-time insights and advanced analytics. BigQuery acts as the central hub for storing and processing data, while Vertex AI enables predictive analytics, such as understanding customer behavior and improving call routing.

Access and usage of the platform are managed through Telenor's Nova platform, which connects the cloud tools and ensures seamless operation across different teams and business functions.

"One major benefit has been moving insights closer to the business areas. We've established over 20 expert users of Looker, and many people can now write LookML themselves," Ingierd says. LookML allows expert users to set up data models that in turn enable non-technical employees to easily build and customize dashboards, reducing reliance on technical teams and streamlining decision-making processes across the company. "This decentralization of analytics has been a huge success, and feedback on Looker and the new tools has been very positive," Ingierd continues. "We now have more users navigating dashboards in Looker than we had with our previous tool. Dynamic filtering and the ease of building dashboards and reports have made the tools much more accessible to non-technical users."

Leveraging AI to improve service quality

With nearly four million customer service calls annually, understanding and addressing customer needs efficiently is a top priority for Telenor. "Our work with Vertex AI has been focused on improving our understanding of customer calls. Reducing the number of calls has a significant impact on both our costs and customer experience — preventing unnecessary calls improves satisfaction," Ingierd says. "We're much better equipped to meet customer service needs, such as analyzing incoming calls and addressing the issues effectively." 

By clustering and analyzing call data, the platform identifies common issues and patterns, enabling predictive routing to the most suitable agents. For instance, if a customer seems interested in purchasing broadband, their call can be directed to a sales specialist, while billing-related queries can be routed to invoice experts or even addressed directly by AI-enabled self-service tools.

"Vertex AI is much more user-friendly than what we had before. It also allows us to include more applications and provide broader access to data," says Ingierd. The platform also opens possibilities for more personalized interactions, such as tailored responses and solutions based on customer data, and emotion analysis during calls to further refine customer understanding.

Preparing for the future with a platform built for scalability and innovation

Google Cloud tools work seamlessly together and are easier for more people to use than anything we've had before. Working with Google has been a great experience. They've been incredibly supportive and committed to helping us succeed.

"The platform will enable us to consolidate data and leverage tools more efficiently, which allows us to focus on prediction modeling and better customer understanding. By reducing the complexity of migration processes and centralizing our data, we're laying the groundwork for deeper insights and more advanced analytics," Ingierd says. 

Moving forward, the team's strategy will focus on minimizing unnecessary data movement while maximizing the efficient use of data across digital channels and market spaces. This approach enables more personalized customer interactions through channels such as mobile apps, email marketing, and other communication touchpoints. By leveraging machine learning for clustering and data analysis, Telenor aims to deepen its understanding of customer behavior.

The goal is to create a more intuitive platform that not only generates actionable insights, but also drives meaningful customer engagement and enhances overall user experience.

"We hope AI technology will continue to improve customer service and uptime. For instance, better integration between our Computer Telephony Integration (CTI) systems and Vertex AI, using APIs, can enhance customer service interactions. This could also extend to other channels and digital touchpoints, improving customer experiences overall," Ingierd says.

Ingierd and his team are looking forward to continuing to work with Google Cloud as the migration progresses. "Google Cloud tools work seamlessly together and are easier for more people to use than anything we've had before," he says. "Working with Google has been a great experience. They've been incredibly supportive and committed to helping us succeed."

With 180 million customers and annual sales of around $12 billion, Telenor is one of the world's largest mobile telecommunications companies. Based in Norway, Telenor operates globally, providing a range of services including mobile, fixed line communication, and broadcasting.
