Overview
About the customer
The customer is one of the largest integrated telecommunications providers in Indonesia, serving approximately 95 million subscribers across mobile, home broadband, and enterprise services. Operating in a highly competitive, multilingual market, the company manages large-scale digital and contact centre operations under multiple consumer and business brands. As part of its digital transformation strategy, the operator set out to modernise customer service and introduce AI-driven automation to improve experience, efficiency, and scalability.
The challenge
Scaling customer engagement in a multilingual, high-volume market
The operator's digital service channels were underperforming against traditional contact points on satisfaction and resolution. A rule-based chatbot delivered inconsistent quality and leaned heavily on human agents, creating four critical pressure points.
01
Inconsistent rule-based chatbot
The existing bot delivered inconsistent resolution quality, driving low satisfaction and heavy dependence on human agents.
02
Chatbot NPS of -10 to +4
Against 40+ for other contact channels, the chatbot was actively eroding customer trust.
03
First Contact Resolution at ~55%
Unresolved queries drove repeated interactions, high agent handovers, and rising operational costs.
04
Fragmented, weakly governed journeys
Journeys were split across chat, voice, and digital, with limited Bahasa Indonesia / English support and no enterprise-grade governance.
The solution
Neo: OBZ's enterprise AI Coworker platform
OBZ designed and deployed Neo, an enterprise AI agent platform built natively on AWS, covering 50+ customer journeys, from sharing information and resolving product queries to recording complaints and raising service tickets. The solution leverages Amazon Bedrock as its AI platform, with Anthropic's Claude Sonnet serving as the core generative AI model, selected for the quality, consistency, and multilingual strength of its responses. Neo is structured across three layers, each with a distinct responsibility.
#Layer 01
Foundry
AI & data foundation, owned by platform teams. Shared, reusable resources made available to every agent.
- Integration with enterprise knowledge bases, APIs, and customer systems
- Centralised data pipelines for conversation history, feedback, and usage signals
- Retrieval-Augmented Generation (RAG) pipelines for grounded, accurate responses
- Anthropic's Claude Sonnet on Amazon Bedrock, with Amazon Lex, for model access and orchestration
#Layer 02
Studio
Low-code agent and journey builder where agents are built, tested, and published to production.
- Visual journey builder for chat and voice workflows
- 50+ journeys: information sharing, query resolution, complaints, service tickets
- Low-code configuration of intents, prompts, personas, and business rules
- Reusable templates via the Journey Bank, with built-in testing and preview
#Layer 03
Command Centre
Operations, governance, and optimisation, with real-time visibility across all live agents.
- Real-time performance monitoring and SLA tracking
- Agent handover management and escalation controls
- Integrated feedback, sentiment, and quality scoring
- Usage analytics, compliance auditing, and guardrail enforcement
