hello and welcome to another episode of
0:09
motals I'm Dave's minion Cuda Pete and
0:11
today will be the first in a series of
0:13
five videos regarding a supply of parts
0:16
to the Chrysler Corporation in the mid1
0:18
1980s from the quality assurance
0:21
perspective a little bit of background
0:23
about myself at the time I was an
0:25
engineering student at the University of
0:27
Detroit and as part of the engineering
0:29
curriculum called op was required I was
0:31
fortunate enough and privileged to get a
0:33
job at the Chrysler Corporation I worked
0:36
as a supplier quality assurance
0:38
specialist in procurement and Supply
0:40
supplyer quality assurance powertrain
0:43
components group powertrain components
0:45
consisted of anything that really bolted
0:47
onto the engine excluding the engine
0:49
itself meaning the fuel system the
0:52
exhaust system cooling system all sorts
0:54
of tubes hoses pipes grommets and
0:57
gaskets and in this I was responsible
1:00
for surveying outside suppliers to make
1:03
sure they maintain consistent quality in
1:05
the parts that they Supply to Chrysler
1:07
so our series is going to be broken down
1:10
into five episodes the first today which
1:12
we'll start off with is
1:14
engineering so the first thing that we
1:17
have to remember is at at the time about
1:19
2third of the parts of the car were
1:22
outsourced meaning they were
1:23
manufactured by an outside supplier
1:25
other than Chrysler Chrysler made
1:27
approximately onethird of the car so in
1:30
order to do that we had to provide clear
1:32
and specific specifications and drawings
1:35
to the suppliers to make sure they knew
1:37
what was required so on the drawings
1:40
there were some critical things that
1:41
were called out the first was a shield
1:44
this meant it was a government
1:45
regulation it usually concerns safety
1:48
emissions or noise and those absolutely
1:51
have to be complied with then the second
1:54
was a diamond this was considered a
1:56
critical Dimension but not regulatory it
1:59
may be an AE asme or aisi specification
2:04
and it was important to the dimensional
2:06
functional parts of the car to make sure
2:09
that they work properly and then there
2:11
was the penar the penar indicated a
2:14
Chrysler internal standard which was
2:16
also critical to the
2:17
part so as I said this information was
2:21
provided to the suppliers so they knew
2:22
what was expected of them now the parts
2:26
could be one of three things the first
2:27
was a blackbox item which meant this is
2:31
already designed and developed it's an
2:33
off-the-shelf part it already exists
2:35
something like a spark plug a battery a
2:38
tire so the engineers would select one
2:41
of these already existing items as a
2:43
black box that would meet the
2:44
specifications and could be used on the
2:47
car as is the second was in-house design
2:51
but outside manufacturing meaning the
2:53
design department at Chrysler would
2:55
design the part but they would not build
2:57
it in house they would send it out to an
2:59
alternate supplier to have it
3:01
manufactured outside and the third type
3:04
was outside designed and developed or
3:06
what was known as oddbox this was using
3:09
an outside supplier's expertise in a
3:11
particular part and rely on them to
3:14
design the part and manufacture it and
3:17
it had to meet the specifications but a
3:20
lot of the responsibility was put on the
3:21
supplier in this case because they were
3:23
considered an expert in this area so all
3:26
this information was provided to
3:28
suppliers in a package and then they
3:30
would bid on it through the purchasing
3:32
department and then contracts would be
3:34
established for the parts and then they
3:35
would be manufactured once it was
3:37
determined if it was going to be a black
3:39
box an inside design or an outside
3:42
design then the engineers had to look at
3:44
certain things to make sure they were
3:46
delivering a quality part and the first
3:48
thing would be the FMEA failure mode
3:51
effect and Analysis and there was a
3:53
manual for that in this manual it
3:55
details how to go about doing an FMEA so
3:58
what is that you take apart and you look
4:00
at it and you say what happens if it
4:02
fails maybe it's just a minor
4:04
inconvenience performance is not as good
4:06
or it's a cosmetic problem or it may be
4:09
something more drastic such as a loss of
4:11
a braking system or a stalling of the
4:14
car so they had to look at all the
4:16
different aspects of what was possible
4:18
what happens if this part fails and what
4:20
is the impact of that failure and then
4:22
obviously try to minimize that so that
4:25
the part would not fail so that was
4:27
something that was important to look at
4:29
but then how do you measure that how do
4:31
you measure the success of your part A
4:33
lot of people just look at well it looks
4:35
good it performs good but you really
4:37
need a metric on how to do that and how
4:39
do you develop that metrics there was
4:41
what we called design of experiments so
4:44
design of experiments is a way of
4:46
scientifically looking at a problem and
4:48
developing a solution that has a
4:50
measurable result and that's usually
4:53
done through What's called the tamaguchi
4:54
method it gave a scientific approach to
4:57
developing tolerances and specifications
5:00
and then at the end you had a metric
5:02
where you could measure a result whether
5:03
it was successful or not so this was
5:05
another aspect of what was used during
5:08
the uh design of the parts and then all
5:11
this information was provided to the
5:13
suppliers so that they knew what the
5:16
requirements were and then they could
5:18
begin manufacturing the parts in our
5:21
next part of the series we will start
5:23
looking at what actually happened at the
5:25
suppliers and supplier quality assurance
5:27
so how those metrics were measured
