Technology Vocabulary|仕様・障害・設計レビューの語彙

技術の会話は「難しい単語」より、物事を分解して話す語彙が必要。ここは“説明・確認・判断”の語彙を固める。

技術語彙の核: requirement / constraint / trade-off / failure mode / mitigation / rollback / ETA
これが言えると、会議で“参加者”ではなく“運用者”になれる。

仕様(Requirements)

核語彙
  • requirement / spec / acceptance criteria
  • scope / out of scope / edge case
  • assumption / constraint / dependency
  • user journey / workflow / use case
確認フレーズ
  • Just to confirm the acceptance criteria…
  • What’s out of scope for this release?
  • What edge cases are we covering?

設計レビュー(Design Review)

核語彙
  • architecture / component / interface
  • trade-off / alternative / rationale
  • scalability / latency / throughput
  • failure mode / resilience / redundancy
レビュー質問
  • What trade-offs are we making?
  • What’s the failure mode if this breaks?
  • What’s the rollback plan?

障害対応(Incident)

核語彙(時系列)
  • symptom / impact / affected users
  • root cause / contributing factor
  • mitigation / workaround / hotfix
  • rollback / restore / recover
  • ETA / postmortem / action items
確認フレーズ
  • What changed right before it happened?
  • What’s the mitigation and the ETA?
  • Are we rolling back or patching forward?

セキュリティ(Security)

  • vulnerability / exploit / patch
  • access control / permissions / least privilege
  • encryption / key rotation
  • audit log / compliance
セキュリティ語彙は“断言”より“確認”が強い:“How do we validate this?”

“do” を卒業する動詞(技術で効く)

do で言いがち置き換え
do a checkverify / validateWe need to verify the config.
do a fixpatch / resolveWe patched the issue.
do a testrun / executeLet’s run a regression test.
do a changeupdate / modifyWe updated the schema.
do a reviewreview / auditWe audited the logs.
