Case Study: Transforming HR with AI-Powered Conversational Agents
About client
Our client is a global leader in advanced, energy-efficient air treatment and climate control solutions. With operations in more than 30 countries and a presence in over 50, the company employs more than 5500 people. Known for innovation and excellence, the organization continuously invests in new technologies to enhance operational efficiency and employee experience.
The challenge
The People & Culture (HR) department faced a growing challenge: an increasing volume of repetitive employee queries around HR policies, benefits, and processes. These questions consumed 30–40% of HR staff time — time that could otherwise be devoted to more strategic, people-focused initiatives. In addition, employees often had to wait for the answers, leading to delayed access to important HR information and frustration. The company needed a scalable AI-driven solution that could reduce the manual workload on HR teams, improve employee self-service, and ensure accurate, compliant responses every time.
The solution
To address these challenges, Digisource Consulting partnered with the client to design and deploy an AI-powered HR conversational agent. Built on Microsoft Azure and integrated seamlessly with Microsoft Teams and Copilot Studio, the solution brought HR knowledge directly into employees’ daily workflows.
Tech stack ​
-
Azure Blob storage for secure policy document management
-
Azure AI Search to index and retrieve HR content in real time
-
Text-embedding-3-large & GPT-4.0 models for accurate, contextual responses
-
Copilot Studio for chatbot orchestration and conversational flow
-
Microsoft Teams as the familiar, user-friendly interface for employees
The solution was designed using a Retrieval-Augmented Generation (RAG) approach, ensuring responses were fact-based, consistent, and aligned with the company’s HR policies. Employees could ask questions directly in Teams or Copilot and instantly receive reliable answers 24/7 — from policy clarifications to process guidance. This setup not only streamlined HR service delivery but also established a secure, scalable foundation for future AI-driven automation across HR and other business functions.
