Renewal work requires finding the right account and product context quickly. A generic chatbot can produce a plausible response, but plausibility is not enough when a sales team is acting on enterprise data and customer commitments.
A GPT chatbot with retrieval-augmented generation inside Webex for sales-renewal workflows. I led the cross-functional product effort, designed the retrieval architecture, and defined the data-governance guardrails end to end.
Retrieval quality, access control, and user trust are coupled. Better recall is not a win if it crosses a data boundary, and a safe system is not useful if it cannot surface the context a seller needs. The product decision was how to make those constraints visible instead of hiding them behind a chat box.
RAG is not merely a technique for reducing hallucinations. In enterprise products it is the control plane for provenance, permissions, and the boundary between what a model knows generally and what a company authorizes it to use.
