  • Case Study: Modernising Customer Support for a Leading Telecommunications Provider

Executive Summary

A top Asia-Pacific telecommunications company, serving over 5 million mobile and broadband customers, was struggling to meet rising customer expectations amidst rapid digital growth. With service inquiries surging, legacy systems, and inconsistent workflows, the business needed to reinvent its customer operations. Through a consulting-led transformation, we designed and implemented a scalable, omni-channel service model that reduced average handling time by 22%, increased first contact resolution by 18%, and established a future-ready foundation for AI-driven customer engagement.

Customer Context

The client is one of the region’s most recognised telecom brands, with extensive operations across mobile, broadband, and enterprise services. As the customer base grew, its support function faced increasing strain, especially around billing inquiries, network service disruptions, and device troubleshooting. The absence of a unified approach resulted in inefficiencies and customer dissatisfaction.

Challenge

The existing customer care model was reactive, fragmented, and costly to operate. Key challenges included:

  • Managing seven separate channels with siloed platforms and processes.
  • Limited reporting capability, resulting in poor visibility into KPIs and missed SLA commitments.
  • Lack of structured workforce practices, reducing agent accountability and creating inconsistent customer experiences.

These issues not only impacted service quality but also limited the telco’s ability to scale efficiently.

Solution

We initiated a 6-week Discovery Sprint to map the current landscape and co-design a modern operating model. Activities included:

  • On-site operational walkthroughs and staff interviews
  • Customer journey mapping and pain-point analysis
  • Data and call volume analysis
  • Technology and IVR performance review

Following the discovery, our team created a 3-stage transformation roadmap:

  1. Stabilisation & Quick Wins – Introduced workflow tools to manage high-volume billing calls and trained agents on rapid-resolution techniques.
  2. Process Streamlining – Standardised processes across channels, eliminating redundancies and embedding consistent practices.
  3. Optimisation & Future Enablement – Rolled out AI-powered chatbots for first-level triage, NLP-driven call routing, and a centralised knowledge management platform.

Outcome

The transformation delivered not only efficiency gains but also long-term strategic value:

  • Strengthened Customer Loyalty & Retention – By improving First Contact Resolution by 18% and reducing repeat calls by 25%, the business created a consistently positive service experience, directly boosting Net Promoter Scores and long-term customer retention.
  • Enabled Sustainable Growth – The omni-channel platform provided scalable support infrastructure, ensuring the business could handle seasonal surges and new product launches without exponential cost increases.
  • Accelerated Digital Transformation – AI-driven triage and NLP-based call routing served as the foundation for the telco’s broader automation strategy, positioning it to leverage next-gen digital tools across the enterprise.
  • Improved Profitability & Cost-to-Serve – A 22% reduction in AHT and streamlined workflows reduced operational costs, freeing investment capacity for growth initiatives such as 5G expansion and new digital services.
  • Future-Proofed Operations – By embedding workforce practices and knowledge systems, the telco built a resilient operating model that can adapt quickly to regulatory shifts, market disruptions, and evolving customer behaviours.

 

 

 

 

 

 

 

 

Strategic Impact

This engagement redefined the telco’s customer operations, transforming them into a strategic enabler of brand differentiation and growth. Instead of being a cost-heavy support function, the customer service organisation is now a key contributor to customer loyalty, operational resilience, and digital innovation. The new model ensures the telco can confidently compete in a saturated market while scaling sustainably for the future.
