Internal copilots fail when teams treat them like science projects. The ones that stick follow a product rhythm: fixed scope, visible milestones, and ownership on the client side after launch.
Week 1–2: discovery and data audit. List document types, sensitivity tiers, and the top user journeys (support, sales, ops). Pick one journey and one document corpus for the MVP.
Week 3–4: build the RAG pipeline, ingestion, chunking, embeddings, evaluation set, and a simple chat UI or Slack/WhatsApp surface. Run security review on secrets, VPC boundaries, and logging.
Week 5–6: harden and hand off. Add admin tools, usage metrics, failure alerts, and written runbooks. Train champions inside the customer team to tune prompts and upload new docs without calling you for every change.
