1
Right, thanks for coming in, Tom.
2
This is a blame-free post-mortem, okay?
3
Is it, though? It doesn't feel like it.
4
I know. The relaunch was painful for everyone.
5
We're here to find the root cause, not a culprit.
6
So, let's start with the timeline.
7
We went live three weeks late. Why?
8
Well, the requirements kept changing, didn't they?
9
Marketing added new pages two weeks before launch!
10
That's fair. That's definitely one lesson learned.
11
And then... the site crashed on day one.
12
Yeah... I know. That one's partly on us.
13
Honestly, we cut the testing phase to save time.
14
So we didn't do any load testing at all?
15
Um, no. We planned it, but it got squeezed.
16
Okay. Thank you for being so honest.
17
And, well... there's something else, actually.
18
The handover from the old agency was a mess.
19
We got almost no documentation from them!
20
Really? Nobody told me that!
21
I did mention it in a stand-up, but...
22
But it never reached me. That's a communication breakdown.
23
So, what would you do differently next time?
24
First, freeze the requirements a month before launch.
25
And never, ever skip load testing again.
26
Ha, I'll hold you to that.
27
Oh, and a proper handover checklist would help too!
28
Great. Let's turn these into action points.
29
Each one gets an owner and a deadline.
30
I'm happy to write the handover checklist.
31
Brilliant! And I'll talk to marketing about the freeze.
32
You know, this was more useful than I expected.
33
That's the whole idea. Nobody's in trouble here.
34
Good. Then I'll bring the biscuits next time.

  • Ha, I'll hold you to that.
  • Let's turn these into action points.

日本語話者が苦手な音：

  • /r/ と /l/ の区別 — /l/ は舌先を歯茎につけ、/r/ はどこにもつけない: partly /ˈpɑɹtli/, differently /ˈdɪf.ə.ɹənt.li/, culprit /ˈkʌlpɹɪt/

  • 子音の連続 — 間に母音を入れない: requirement /ɹɪˈkwaɪɹmənt/, freeze /ˈfɹiːz/, painful /ˈpeɪn.fl̩/, partly /ˈpɑɹtli/, differently /ˈdɪf.ə.ɹənt.li/

この動画での練習方法

  1. まず声を出さずに動画を最後まで聞き、知らない単語をメモします。
  2. 通常の速度で一文ずつシャドーイングし、話し手のリズムに合うまで繰り返します。
  3. 自分の声を録音して元の音声と比べます。requirement, freeze, lessonなどの単語に特に注意しましょう。

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
