Domain depth before model novelty

A newer model cannot replace missing process knowledge. Builders need access to experts, documents, systems, exceptions and decision history to understand the real operating environment.

Evaluate the whole work cycle

Accuracy on a single answer is insufficient. Teams should test retrieval, decisions, tool calls, state transitions, escalation, latency, cost and final outcomes across realistic cases.

Build reusable infrastructure carefully

Shared integrations, identity, observability and governance can accelerate multiple verticals. Reuse should never erase local regulation, terminology, risks or human responsibilities.
