Shadowing Practice: The Three NPI Phases Explained - Learn English Speaking with Video
Creando lección...
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.

¿Qué es la Técnica de Shadowing?
Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
