技術英語の聞き取り|仕様・障害・設計レビューで勝つ
技術会話は「語彙」より情報の種類を拾うゲーム。拾う項目が決まれば、聞ける。
技術会話の勝ち筋:
① 何が壊れている?(symptom) ② 何が原因候補?(cause) ③ どう直す?(mitigation) ④ いつ直る?(ETA) ⑤ 影響は?(impact)
① 何が壊れている?(symptom) ② 何が原因候補?(cause) ③ どう直す?(mitigation) ④ いつ直る?(ETA) ⑤ 影響は?(impact)
シーン別:拾うべき“項目”
| シーン | 拾うもの |
|---|---|
| 仕様説明 | inputs/outputs, constraints, edge cases, success criteria |
| 設計レビュー | trade-offs, performance, security, failure modes |
| 障害対応 | symptom, timeline, root cause, rollback, mitigation, ETA |
| 進捗 | status, blocker, owner, due date, dependencies |
略語が聞こえない時の運用
- Sorry—what does “___” stand for?
- Can you spell that acronym?
- Is that the same as ___?
略語を放置すると後半全部が崩れる。早めに止める。
数字・単位(ここが事故る)
- ms / sec / minutes(時間)
- MB / GB / TB(容量)
- requests per second(負荷)
- percentile(P95 / P99)
聞こえたら必ず復唱:“P95 is 120ms, correct?”
確認テンプレ(技術版)
仕様確認
- Just to confirm the success criteria: ___, ___, and ___.
- What are the edge cases we’re worried about?
- What happens if ___ fails?
障害対応
- What’s the impact right now—who is affected?
- When did it start, and what changed?
- What’s the mitigation, and what’s the ETA?
設計レビュー
- What trade-offs are we making?
- What’s the failure mode if this component goes down?
- Can we outline the rollback plan?
“聞けた風”をやめる(信頼が上がる)
- 分かったフリ → 後で破綻
- その場で確認 → プロ
技術では“正確さ”が礼儀。
Mini Simulation(障害対応の聞き取り)
Lead: We’re seeing P95 latency jump from 120ms to 900ms since the deploy at 2:10. Impact is about 30% of users.
You: Just to confirm—deploy at 2:10, P95 is now 900ms, impact 30%, correct? What’s the mitigation and ETA?
Lead: Rolling back now. ETA 15 minutes.
You: Got it—rollback in progress, ETA 15 minutes. I’ll capture timeline and next steps.
