The experts mapped the field maintenance workflow and found technicians lost time arriving without the right parts and searching dense manuals on-site. They built a custom mobile app that reads real-time IoT sensor data to pre-diagnose likely failures and recommend parts before dispatch, plus a conversational chat interface that returns targeted manual excerpts on demand. Field technicians completed repairs in about 40% less time.
The app was built on LangChain and a vector database, using an LLM with vector search across indexed service manuals to pre-diagnose failures and surface repair guidance. The approach combined knowledge management (RAG), a conversational AI interface, and predictive analytics groundwork.
Three outcomes: a 40% reduction in time to service, full ROI recouped within about one year, and a richer structured maintenance-record dataset that became the foundation for future predictive maintenance modeling.
About three months, running from initial workflow analysis through full deployment, with efficiency gains landing in the first quarter after go-live.
