曖昧性は実務では常態です。沈黙で静かに推測し、間違ったものを構築するのではなく、積極的に不確実性を削減できることを示す必要があります。
なぜ重要なのか

1. Ask the questions that change what you'd build
2. Find the goal behind the request (the "why")
3. State your assumptions in writing and confirm them
4. Build a thin slice, demo early, adjust fast
実例
text
S: A ticket said "add a dashboard" with no detail on metrics or users.
T: Building blind risked weeks of wasted work.
A: I asked who'd use it and what decision it drove, wrote down three assumptions,
and built a clickable prototype of the top two metrics first.
R: The demo surfaced that they actually needed exports, not charts. We pivoted
after two days instead of two weeks.

✓ Clarifies the "why," states assumptions, demos early
✗ Building the full thing on a guess
✗ Refusing to start until everything is spec'd
