쉐도잉 연습: The Three NPI Phases Explained - 영상으로 영어 말하기 배우기
레슨 만드는 중...
1
Then you say you start your NPI process
2
and this is comprised of three phases and after
3
that it's really ready for ongoing mass production and ramp up of the volumes, right?
4
Correct.
5
So what are these three phases?
6
So the three phases are engineering validation, design validation, and production validation.
7
Some people, a lot of people are familiar with these terms
8
but they're not familiar with what the actual meaning is and how you qualify from one phase to the next.
9
So a lot of people have misinterpreted this to mean that you've got three chances to build it and get it right.
10
That's not correct.
11
Each phase has different meaning.
12
So the engineering validation you want to prove out from an engineering point of view that your tooling is good, your enclosures are good, your PCBA is good,
13
that your features are all present and that your device is working as intended.
14
At the end of an ADT build you should sit in a room with all of your engineers
15
and all of them can say that their functions have been complete and this product is performing as expected.
16
So the output is not only a prototype that's much closer to what's intended
17
because it is made this time with the same manufacturing process as it is intended, it also comes on the supply chain side with a BOM,
18
so you already started to select the component suppliers, you've been working very closely with obviously also the assembly and testing supplier.
19
On the technical side you've gone into all the details of the design, the mechanical design, engineering design, the firmware design and so on.
20
Is that correct?
21
That's correct, yes.
22
So that EBT part that you've built should be fully representative of your supply chain and your processes.

How to practise with this video
- Listen to the whole video once without speaking and note the words you do not know.
- Start at 0.75× speed, shadow it sentence by sentence, then go back to normal speed once it feels easy.
- Record yourself and compare with the original, paying attention to words like validation, intend, supplier.
쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법
쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
