Next Best Question (NBQ)
Next Best Question is a conversational design and decisioning pattern where a system asks the single most valuable clarifying question to progress toward a correct outcome.
NBQ improves correctness, reduces hallucinations, lowers cost (fewer wasted tool calls), and increases trust—particularly for C-level and developer audiences who hate "confident.
Explanation
Instead of generating a long answer with assumptions, the system optimizes for information gain: ask what reduces uncertainty the most while minimizing user friction. NBQ is especially useful in tool-using agents and RAG when missing constraints can cause wrong actions.
Marketing Relevance

Example
User: "Set up monitoring for our RAG." NBQ: "Is this for quality (groundedness), latency/cost, or security/audit?"

Asking too many questions; asking questions users can't answer; not remembering answers (bad UX).
