Hello everybody, my name is Ken Phalan, and yet again from the disment of Alistair one
|
|
rule.
|
|
Is that correct?
|
|
That's right, yeah.
|
|
So Alistair, what do you want to talk to us today about?
|
|
I wanted to talk to you about PLM software, which is something I've recently got involved
|
|
with, thrown into the defense, and it's just a fascinating subject that people might not
|
|
know much about.
|
|
What's PLM?
|
|
It's product lifecycle management.
|
|
The idea at one time day was if you wanted to design something, you would use a piece of
|
|
CAD software.
|
|
If you wanted to keep records on something, you would use a database.
|
|
If you wanted to keep financial records, you might use a spreadsheet.
|
|
And the problem that gave people who were making products was that the guy who was designing
|
|
on the CAD software, his software wasn't compatible with spreadsheets and the spreadsheets
|
|
and the CAD software weren't compatible with the database.
|
|
So every time anyone needed to pass any data between those subjects, there would be a
|
|
long delay while it was translated from one piece of software to the next piece of software.
|
|
PLM gets around that by saying you will use one piece of software for everything.
|
|
You will start designing whatever it is.
|
|
In my case, it happens to be airplanes, Airbus that I work for.
|
|
If you want to design an airplane, you will start using the pieces of where I use this
|
|
thing called Katia.
|
|
It's also known as DelMia.
|
|
It's all done by DassoSystem and you will start designing the airplane on Katia and
|
|
DelMia.
|
|
When you go into production, you will still use Katia and DelMia.
|
|
You will still use the same pieces of software.
|
|
When it goes into actual use, when the plane gets sold to the airline, they will still use
|
|
the same piece of PLM software to keep track of all the maintenance, to keep track of all
|
|
the technical aspects of the airplane.
|
|
Even after the airplane lands for the last time and they have to break it into its component
|
|
parts and recycle it all, they still use the PLM software to see what went into the
|
|
making of the airplane in the first place.
|
|
The whole life cycle of the entire project is entirely encapsulated in one piece of software.
|
|
There is no delays in transferring information between one group of people and another group
|
|
of people because they are all using exactly the same thing.
|
|
Does that kind of go against the Unix philosophy of many tools, each doing a small job, doing
|
|
a problem?
|
|
All these tools are on Unix, but that philosophy hasn't been strong enough to overcome the
|
|
flaws of, they call it over the wall problems where you have to pass information to somebody
|
|
doing a different job.
|
|
So it's at the moment not something which the open source world is heavily involved
|
|
with at all.
|
|
It's very much a proprietary idea.
|
|
Why I'm so interested in it is because of the efficiency gains that they've got from
|
|
this.
|
|
They've taken the cycle of getting an airplane as a concept through to an actual flying
|
|
airplane down from 12 to 15 years down to 6 to 8 years.
|
|
It's been a massive shrinkage in the amount of time it takes to actually get a product
|
|
out into the actual world.
|
|
So if they're gaining that kind of efficiency, there's obviously something to it which is
|
|
interesting, but there's a niche that the open source community should be coming rushing
|
|
into the build.
|
|
As much as anything it's a way of thinking and there's got to be something there for companies
|
|
like Airbus and all the other companies such as the big car companies, Ford, Waxel,
|
|
and all those people are using it.
|
|
For them to invest that amount of money into it, there's got to be something there of
|
|
value which is why I'm interested in it.
|
|
I've got to, you know, as a new to the topic about the length of this eye cast, the new
|
|
to the topic.
|
|
You know, Todd Johnson to remind, well, you know, in the life cycle, you're talking about
|
|
lung projects there are playing to be playing for 20 years.
|
|
And this, you know, think back now, software in 1970s or something, and that's, you expect
|
|
that to still be running when this plan is over.
|
|
I don't think it claims to completely solve that problem with fragmented groups of software,
|
|
it just exacerbates the problem because you've got to solve the problem once for the database,
|
|
then again solve it for the cabs, then you've got to solve it for the spreadsheets and
|
|
so on and so forth.
|
|
If you bring it all into one, as PLM has done, then you only have to solve that problem
|
|
one time over.
|
|
But does that end up bringing you super underlocking?
|
|
Yes.
|
|
You know, two years down the line, this company will go, okay, you're bought in, you're
|
|
now committed, you have no choice but to continue using this software, it would even
|
|
be who you to buy the company who is developing this software.
|
|
That's definitely a big fear with it.
|
|
I have no idea personally how open source would solve that problem.
|
|
And that's one of the things that I would like to talk about, if anyone has any ideas
|
|
about how you would solve that problem, by all means getting in touch with me at the email
|
|
address, which would be at the bottom of the screen, I guess.
|
|
It will be in the short notes, but that's absolutely fine.
|
|
Thank you very much, Alistair, it's been a very intriguing topic.
|
|
It's good to have an over-tentative beer on the open source, on the hack-and-pop beer,
|
|
what you've just highlighted at the top of the cup, we have a lot of interest to a lot
|
|
of our listeners.
|
|
And if some of our listeners has any more expertise on this, feel free to record a show
|
|
and send it in to our group at the beginning of the day.
|
|
Thank you very much, and enjoy the rest of the show.
|
|
Thank you.
