Artificial intelligence is revolutionising customer service, but its adoption must be measured and strategic. A recent study shows that 84% of organisations already use AI in their customer service, but only 28% believe they have reached a satisfactory level of maturity.

In a context where customers expect instant and personalised responses, the "augmented manager" approach accelerates interactions while freeing advisers from repetitive tasks. The aim is not to replace humans, but to augment them intelligently.

Worldline CX Suite offers a balanced vision: combining intelligent copilots, automated workflows and robust governance to create a superior, measurable and ethical customer experience.

Real-time personalized experiences through generative AI

According to Gartner, by 2025 around 80% of customer interactions will be assisted by generative AI. This technology enables rapid creation of conversation scripts tailored to the customer profile, generation of personalised and contextualised email drafts, and instant synthesis of complex tickets to accelerate decision-making..

Sector feedback: B2B telecommunications : According to IBM, deploying generative AI to automatically generate personalised sales proposals has increased conversion rates from 35% to 50% and reduced offer preparation time by 40–60%.

Guardrails and governance

Governing this creative power remains essential. Worldline CX Suite includes automatic safeguards; full traceability of sources used, real-time factual verification, automatic adherence to customer preferences, and human validation for sensitive content.

This balanced approach allows organisations to harness AI speed while maintaining the quality and authenticity of interactions.

Measuring ROI and effectiveness: KPIs for the augmented agent Measuring AI effectiveness in customer service requires multidimensional metrics that capture both operational gains and impact on the customer experience. Key KPIs include the adoption rate of AI copilots by advisers, average handling time pre- and post-deployment, first-contact resolution rate, perceived quality of AI guidance, and customer satisfaction post-interaction.

According to Deloitte, organisations that master AI in customer service typically realise: 

With benefits materialising after 12 to 18 months of deployment and ongoing optimisation.

ROI is not limited to direct savings: it is also important to assess impact on customer retention, increases in customer lifetime value and improvements in employee engagement.

Worldline CX Suite provides an integrated dashboard that correlates these metrics to offer a holistic view of performance.

This approach, documented in Capgemini’s best practices, helped identify and correct biases early, tailor training, and achieve buy-in from more than 90% of advisers in the end.

Advanced observability is a core pillar: detailed logs of every AI interaction, real-time performance and quality metrics, and automatic rollback plans in case of anomalies. This architecture ensures service continuity while enabling continuous improvement of the algorithms.

Change management: putting humans at the heart of transformation

The human factor is key to success.

According to McKinsey, 70% of AI transformations fail due to poorly anticipated change resistance. Companies that invest in human change management — training, communication and support — triple their chances of success.

Technology alone is not enough; successful transformation requires structured human support. This begins with:

• Transparent communication: objectives, benefits, impacts on roles
• Comprehensive training: AI fundamentals, ethical considerations, data governance

The way work is organised is also evolving: emergence of cross-functional AI‑CX teams, creation of roles such as AI Trainer and Conversation Designer, and governance mechanisms that clarify responsibilities.

Worldline CX Suite supports this organisational transformation with certification programmes and communities of practice.

Conclusion: towards responsible and high-performing AI

AI and automation in customer service are not intended to dehumanise the relationship but to make it richer and more effective. By combining augmented agents, generative AI and emotional intelligence within a robust governance framework, organisations can create exceptional customer experiences while improving satisfaction and employee engagement.

Success rests on three pillars: cutting-edge technology such as Worldline CX Suite, a progressive and measured deployment methodology, and structured human support. The ultimate aim is to build intelligent, ethical and high-performing customer journeys that benefit all stakeholders in the ecosystem.
