Why Data Management?

I often get the question from customers asking, why they should use
Autodesk Vault or Productstream. They have their way of working now and it
works well for them. Well, perhaps if I can give my personal reasons why,
maybe everyone reading this article will understand a little better why we
try to drive our customer base to adopt data management applications.
I used to work in the auto industry, where we sometimes had to design and
build production machinery in less than two or three weeks so that we could
have them ready for production in a timely manner.
When working on the smaller projects that only required one engineer, we
would usually work with them on our local PCs to avoid network traffic. Some
of the designs we were creating consisted of several hundred files of
components, assemblies and drawings. Opening large assemblies over the LAN
would sometimes take a considerable amount of time and it was more efficient
to just work locally.
In certain cases we would have to travel several hours to a production
facility for design review, or overnight hard copies to the customers for
extended conference calls. Sometimes drastic performance changes or simple
esthetic changes were requested. In either case, we had no backup of the
data from the time of the Design Review unless we saved the files with some
intelligent naming convention including a date and creating multiple copies
of the same design with differing file names.
Another issue was once our assembly concepts were complete and it was time
to assign company part numbers to the components, we would have to go
through and rename each of the files individually (hoping not to reuse the
same part number for multiple files) in Windows, then fix the unresolved
links between the files (in both Mechanical Desktop and Autocad at the time,
much the same as today’s 3D environment with all of the parametric solid
modelers).
Collaboration on a design had its difficulties as well, as we constantly
overwrote one another’s work, undoing work, making destructive changes or
losing data altogether. Some examples of these were an assembly I worked on
had several automation components added. When I left for vacation, another
coworker removed some necessary components by accident and had no idea he
had done so. Additionally, he made changes to the drawings that would make
manufacturing outrageously expensive. The only way we knew who made these
serious errors was his admission of making these changes. These changes
caused the project to be three weeks late and a little less than $20,000
over budget.
Releasing documents for production was a nightmare, to say the least. At the
time, we had no formal release process for production, other than placing a
revision letter in the titleblock. This caused a very serious problem with a
project on which I worked. While I was away from my desk, my boss grabbed a
drawing packet from my desk and took them with him as he was leaving to
visit a vendor. The packet he took however was not for release, rather for
checking. Even though I mailed a released drawings packet to the vendor,
several weeks later when those parts were delivered to my shop, not one
component matched the “released” drawings. Most were off by a few
thousandths here and there, nonetheless inaccurate. After checking with the
vendor, he built to the prints my boss delivered and not the prints I
mailed. The end of the story is I had about $50,000 of metal in a crate that
was worth about $2,000 in scrap.
So you may be asking yourself, how can a tier 1 company in the auto industry
have so many Engineering Data Management problems? That answer is simple; we
had no Engineering Data Management solution at that time that was worth the
money. Knowing what I know now about Vault and Productstream, every data
management issue we had while at that company would have been completely
preventable.
How would our lives been different if Vault and Productstream been in place
ten years ago? We simply could have used its history tracing capabilities
for tracking my design history. When the time came to change back to an
earlier instance in the design due to a design review, we could have had the
previous history to go back to, without having multiple files stored on our
hard drive or server. Additionally, our overall productivity would have
increased as we would not have had to continuously travel to our production
facilities for design reviews; all communication for change could have taken
place in Productstream rather than in several notebooks and emails and
marked up paper drawings.
Our continuous overwriting of each others’ data would not have occurred
because only one person could have a design file checked out at time, and it
would have been versioned and updated locally upon check out on each others
machines when they needed to make changes. In the cases I mentioned above
would not have been over due and over budget because of one person’s
mistakes. Additionally, renaming the files from intelligent names like
flywheel to corporate numbering schemes such as 50-956847, would have taken
minutes rather than the hours we spent trying to reconnect the links between
the files.
Had Productstream been in play at the time, we would have been able to
release our documents, and publish them to SharePoint server whereby giving
my vendors access to the released drawings we wanted them to have and when
we wanted them to have the drawings.
Overall, It’s easy today and think of how much more productive we could have
been ten years ago, had the technology been what it is today. But the fact
of the matter is, we have the technology today to reduce the frustrating
issues of file management, release management and change management. Now
it’s all up to you to make the decision to address the following questions:
 |
What problems do I have with collaboration today? |
 |
How
often do I lose a file in my server, only to find it several weeks later
when I no longer need it? |
 |
When I do know where a file is stored, about how long does it take to
get to it, and open it in my cad system? |
 |
What nightmares do I have when I know I have a large assembly to rename?
|
 |
Do
I ever take an existing design and change 30 percent of it for a
different design need? |
 |
Have I ever had the need to make a change, then roll back that change to
an earlier state? |
 |
What does my change process look like? |
 |
How
do I release components for production? |
 |
If
I do, where is all of this data documented and stored? |
