The Problem: Senior Staff Buried in Routine Triage
A 2000+ employee UK insurer running customer support across claims, billing, and policy services faces a specific bottleneck: senior staff spend 15-20 minutes per inbound call or email on initial triage—listening, categorizing, and routing the ticket to the right queue. This routine work consumes the time of licensed adjusters and senior support leads who should be handling complex claims, not classifying tickets. The goal is not to replace human judgment on policy decisions or payouts, but to free senior staff from the mechanical first step so they can focus on the work that requires their expertise. A voice agent that transcribes, classifies, and routes tickets, with a human approval gate before assignment, addresses this directly. The pilot is fixed-scope: one workflow, one department, two weeks, with a measured before/after baseline on cycle time and error rate.
Prerequisites Before Step 1
Before the pilot starts, confirm these are in place:
- Helpdesk or CRM API access: Read/write credentials for the ticketing system (e.g., Salesforce, Zendesk, or a custom in-house tool). The agent needs to create, update, and route tickets.
- Slack or Microsoft Teams workspace: The team where support staff already operate. The agent will post ticket summaries and routing decisions here.
- Historical ticket sample: 50-100 tickets from the last 90 days with their final routing decisions. This is your training and validation set.
- Ticket category taxonomy: A defined list of categories (claims, billing, policy changes, complaints, other) with clear routing rules for each.
- GPU hardware: A machine with 24GB+ VRAM (e.g., an NVIDIA A100 or a cloud instance like AWS p4d.24xlarge) for running the open-weight model on-premise.
- Named business owner: A person with authority to approve the pilot scope, success metrics, and go/no-go decision at the end of week 2.
Step 1: Run the Process Audit and Capture the Baseline
Run a 2-hour process audit with the support team lead. Map the current triage workflow: where the ticket enters, who touches it, how long each step takes, and where errors occur. Capture the baseline: median cycle time from ticket creation to correct routing, and the percentage of tickets that required re-routing after initial assignment. This baseline is your before/after reference. Without it, you cannot measure whether the agent actually improved anything. Document the ticket categories and routing rules in a one-page spec that the business owner signs off on. This spec locks the scope for the 2-week pilot.
Step 2: Fine-Tune the Open-Weight Model on Historical Tickets
Fine-tune an open-weight model (Llama 3 70B or Mistral 7B) on your historical ticket sample. The model’s task is classification: given a ticket’s text (transcribed from voice or typed), output the correct category and a confidence score. Use a standard fine-tuning framework like Hugging Face Transformers with a classification head. Train for 3-5 epochs on the 50-100 ticket sample, validating on a held-out 20% set. Target 85%+ accuracy on the validation set before moving to integration. If accuracy is below 80%, expand the training set or refine the category definitions. The model runs on your on-premise GPU, so no ticket data leaves the building.
Step 3: Build the Voice Agent and Integration Layer
Build the voice agent’s transcription and classification pipeline. The agent receives an inbound call or email, transcribes it using a speech-to-text model (Whisper or an equivalent on-premise option), and passes the text to the fine-tuned classifier. The classifier outputs a category and confidence score. If the confidence is above 0.85, the agent routes the ticket to the correct queue in the helpdesk and posts a summary to the relevant Slack or Microsoft Teams channel. If the confidence is below 0.85, the agent flags the ticket for human review. The integration uses the helpdesk’s REST API to create and update tickets, and the Slack/Teams webhook to post notifications. No new systems are introduced—the agent plugs into what you already run.
Step 4: Deploy with Human-in-the-Loop Approval
Deploy the agent in production with a human-in-the-loop approval gate. Every ticket the agent routes is visible to a named human reviewer in Slack or Microsoft Teams. The reviewer approves or corrects the routing before the ticket is assigned to a queue. This gate is non-negotiable for the pilot: it ensures that no ticket is mis-routed without a human catching it. Track every approval and correction in a simple log. The log feeds directly into the before/after comparison at the end of week 2. The agent does not make decisions about payouts, policy terms, or contract changes—those remain with licensed staff. The agent’s job is to get the ticket to the right person faster.
Step 5: Measure the Before/After Baseline and Present Results
Run the pilot for 5 business days in week 2. Collect data on: median cycle time from ticket creation to correct routing, routing accuracy (percentage of tickets sent to the right queue without human correction), and senior staff hours saved per week on routine triage. Compare these numbers against the baseline captured in step 1. A successful pilot shows a 40-60% reduction in cycle time and 85%+ routing accuracy. Present the before/after comparison to the business owner with the raw data and the approval log. The go/no-go decision is based on these numbers, not on impressions. If the metrics meet the threshold, the next step is scaling to additional departments or ticket categories.
