Shadowing Practice: 4 NPI Tips Before You Move Into Mass Production - Learn English Speaking with Video
Creando lección...
1
Remember, and again, this is really all about setting expectations.
2
Working on your prototype is not a quality standard.
3
Define acceptance criteria in writing before you build mass production.
4
Yes, you can test and you can validate the prototype.
5
Yes, this is basically the direction I'm going to go in.
6
This is what it's going to look like.
7
Even rough colors.
8
OK, this is not your quality acceptance criteria.
9
OK, you really, really need to understand what that means.
10
And it is very different to what you're looking at from a prototype point of view.
11
OK, I'm just trying to set your expectations of what you should be doing.
12
OK, let me pick another one.
13
Let's look at this MPI.
14
okay if you haven't got a structured mpi process in place with controlled processes with
15
phase gates let's say you need to make sure you have you need to make sure
16
that you're working with a contract manufacturer that has a solid robust mpi process in place with phase gates
17
and they are strong enough in order to say mr customer
18
we are not ready to move into the next phase because instead of being, oh yeah, sure, no problems, we're moving, no, no problems.
19
And then all of a sudden, we've got 10,000 units with 10,000 problems.
20
Really have that MPI process in place.
21
One way can check, do your audit.
22
Yes. And
23
if you're thinking what does the structured mpi process look like
24
well we do have a graphic form of the mpi process
25
that we follow that you might like to use as reference i think you've got another couple of pro tips
26
okay yeah if we've got time yeah no problems track every unit in your validation build okay Now,
27
your validation build, again, we're building some just in the next room alone.
28
Okay, I've got building 10 units.
29
Each one of these has got its own serial number on.
30
Guess what?
31
It's 1 to 10.
32
Okay, but we know exactly what is being tested, when it's being tested, who's testing it, what the results are, and what that unit number is.
33
Okay, and each one of those has its own variations within the test output.
34
okay now what we're doing here is we're building 10 now this is like the dbt okay
35
or tooling validation okay so we're not quite at production yet
36
but we have identified some small areas
37
that need to be improved in order to that product to go into mass production and be built reliably consistently and robustly.
38
Okay, so track.
39
Don't just like get 10 prototypes built.
40
Yeah, they all work, but this one was like a little bit off.
41
Let me send them all back to you.
42
And you didn't actually identify which one was wrong.
43
Then we're going to get that back or your contract manufacturer or your developer's going to get back and say, I'm going to make the assumption that it's this one
44
because it feels different to me as opposed to you didn't mark it up okay
45
so serial numbers is really important and particularly on the unseen aspects software
46
and firmware okay super super important software and firm
47
and have your tracking or serial numbers encoded in okay super important particularly
48
when it comes to that debugging
49
or cleaning up process okay there you go it's another pro
50
tip um moving factory i've talked about this before i'll talk
51
about again make sure you understand what the factory you're working
52
with has everything in place with respect to qualifying a new
53
production run now prototypes to mass production okay that's sort of understandable
54
but what if you're going from mass production to mass production now we we have those scenarios as well
55
and we will not take a product on until we've done a validation
56
or a pilot run even if
57
that is a mature product okay why we've got a different
58
set of people okay it's a different set of eyes different set of hands actually putting
59
that product together okay so this is what you need to insist
60
that if you're transferring a product from one factory to another
61
or one contract manufacturer to another contract manufacturer you insist
62
that they do a small pilot run okay in order to
63
prove the new process is correct maybe it's the old process
64
but there's a new interpretation of
65
that okay then you can actually understand what your failure rates are what your yield rates are
66
once you understand that you can do your quality analysis to your eight days
67
and all the rest of it but the key thing is you don't just transfer
68
and say well i was building 10 000 last month
69
and this supplier and everything is perfectly okay i'm going to transfer
70
and expect the same okay it doesn't happen okay it's almost like starting from scratch
71
but you know at least have
72
that pilot run in there okay now a lot of people transfer
73
because of cost because of quality issues because of of personnel issues.
74
They're all valid, all valid reasons, okay?
75
But put cost back on the table if you are transferring 10,000 bill per month,
76
10,000 bill per month without that trial, okay?
77
The cost of failure of 20%, for example, is huge, absolutely huge.
78
All you have to do is like scale back for a little while
79
do that pilot run make sure everything is okay then you can ramp back up okay
80
so if you're doing that factory transfer be very careful

¿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.
