What & why

What it is
A questioning sequence that opens with broad, open-ended questions and progressively narrows toward specific, actionable detail. The wide start invites context and lets the other person frame the topic; each following question tightens the focus, building on the previous answer. It moves from the general to the precise so understanding is established before specifics are pinned down, ending with concrete, decision-ready information rather than jumping straight to detail or staying vague throughout.
Why it works

Opening wide lets the other person frame the topic in their own terms, which lowers pressure and tends to surface context and priorities a narrow question would skip. Each tighter question then builds on what they just said, so the conversation feels guided rather than interrogated and is easier to follow. Working from general to specific also respects working memory: broad ground gets set before details land, so nothing arrives without context. The narrowing momentum tends to move people toward concrete, committed answers by the end.

Before & after

Before

“Jumping straight to specific details without context, staying too broad without getting actionable.”

After

“What's your vision? ... What would success look like in 90 days?”

When you’ll use it

Requirements gathering: 'Tell me about the project' → 'What specific outcomes matter most?' → 'By when do you need result X?'

Root cause analysis: 'What's happening?' → 'When did this start?' → 'What changed right before that?'

Sales discovery: 'What's driving this initiative?' → 'What's your budget range?' → 'Who else needs to approve this?'

Performance reviews: 'How do you feel about this quarter?' → 'Which project was most challenging?' → 'What support would help?'

Pro tip

Think of an upside-down pyramid: broad at the top, specific at the bottom.
