Process before model
An AI assistant should not be planned as an isolated chat window. The workflow matters more: input, follow-up questions, knowledge search, structured data, action and handoff. Once that is clear, model choice, RAG, integrations and automation logic become easier.
Boundaries create trust
Good AI feels professional because it does not promise everything. It marks uncertainty, works with approved sources and hands sensitive, unclear or costly decisions to humans. Those boundaries improve adoption for teams and customers.
Start small and measure cleanly
The best entry point is a focused use case: pre-qualify requests, search documents, prepare email drafts or structure CRM data. Then quality, time savings, error paths and conversion can be assessed realistically.
