IT’S A PERFECT LAUNCH
FRESH
MEADOWS, NY – If you’re Lockheed Martin Space Systems, ready to
launch the new millennium with up-to-date, Y2K compliant missile assembly
programs, how do you meld the future with the past?
This was the position Lockheed Martin found itself in when
it decided to replace a Cobol-based documentation system with an Oracle database
application. The Cobol documentation, in conjunction with LMSS’s
publishing system, produced procedural “work packages” involved in missile
assembly. A specific package is
created for each part of the assembly, and thirteen packages are required to
build a complete missile.
The Problem
The existing documentation had been authored in XICS- (Xerox
Integrated Composition System) encoded ASCII text. The documentation needed to
be converted to SGML (standard generalized markup language), a
rapidly-spreading standard for tagging text, tables and graphics.
Specifically, LMSS’s data had to be encoded in accordance with the IMPS
DTD (document type definition) the company had developed.
The SGML standard is becoming the de facto standard in the
world of complex technical documentation. The standard allows documents to be
transferred across platforms and displayed properly across media (Internet, CD,
printers and screens). Other benefits of SGML include hyperlinking that would
not be possible in traditional publishing systems, and more refined search
capabilities.
Lockheed Martin had 25,000 critical pages currently in use
(with missile manufacturing systems) that needed to be converted almost
immediately. Another 225,000 pages were to be converted by LMSS for archival
purposes at a later date.
As with any precision data conversion, the very nature of
how the data was being used meant
the conversion had to be 100 percent accurate. The complexities of the Lockheed
Martin data made this a formidable task.
Aside from the difficulty of converting text in standard
XICS markup to SGML, specific XICS tags and markup had been used in non-standard
ways by various authors. In fact, as LMSS’s Mark Ferrara, the
Conversion Project Lead, discovered, there were many more of these than
anticipated.
“When we first raised the question of doing the
conversion, we knew we couldn’t do it in-house with our own resources,”
Ferrara stated. “We had no SGML conversion ability in place.
The very nature and volume of what we had to convert, coupled with our
tight delivery schedule, meant we needed the expertise of an outside facility
with considerable SGML experience. We
also knew our own special tags and exceptions would present problems in creating
conversion software. Given the
challenges, there was some skepticism as to whether it could be done at all
within the time allotted.”
LMSS and DCL
Ferrara met a Data Conversion Laboratory spokesperson at an SGML conference
in 1997. At that time, Lockheed
Martin was first considering conversion related to another project, but hadn’t
yet decided to move on it. “We
were checking out resources and companies,” Ferrara noted.
“This was our first large-scale conversion and we’d heard horror
stories, and read case studies, about conversions gone bad.
We didn’t want ours to be one of them, especially this project.”
After reviewing several other companies, Ferrara was
convinced that Data Conversion Laboratory (DCL), with its SGML expertise and an
outstanding reputation for high-quality, on-time, on-budget work, matched his
needs. Contracts were signed in August, 1998, calling for DCL to convert the
25,000 critical pages at their facilities. Upon completion of that phase, DCL
would license the conversion software to Lockheed Martin so the company could
convert its remaining 225,000 pages in-house, as needed.
The Process
In the trial or “proof of process phase” of a project this complex, DCL
typically does a sample conversion of selected data or text—usually the most
difficult data to be converted—in order to test the conversion software for
accuracy.
Howard Shatz, DCL project director, reflects,
“In this early phase, many of our clients find it difficult to understand the
complexities of the process and how they can help. Mark Ferrara and LMSS were
very forward-thinking.”
Ferrara and LMSS presented DCL with a XICS-to-SGML
standard conversion map, and instructions for handling exceptions.
According to Shatz, “this was an enormous, time-saving help. We
incorporated LMSS’s templates and tried one or two iterations of the
conversion software on sample documents. As is usual in these types of
conversions, these early iterations identified new exceptions. We went back and
forth, incorporating exceptions and ironing out the kinks.
In a few short weeks, we were able to convert the most difficult data
from XICS to SGML with 100 percent tagging accuracy.”
Ferrara compliments Shatz on this phase of the process.
“DCL was very patient with us, often going the extra mile and doing things
above and beyond the call to make the adjustments and get the software to 100
percent,” he noted.
The Solution
In November, 1998, the conversion software was ready and
the conversion shifted into high gear.
“From that point on, DCL sent us 1,500-2,500 pages a
week. The quality and accuracy were outstanding. The entire conversion of the
first 25,000 pages finished exactly on time, at the end of January, 1999. It
also finished on budget. This is
remarkable because the budget had been drawn up 15 months earlier, before anyone
knew how complex the job was,” Ferrara added.
At the completion of the critical 25,000 pages, DCL not
only licensed the conversion software to Lockheed Martin (to convert the
remaining 225,000 pages in-house), DCL’s technical advisors helped LMSS’s
programmers become familiar with the software in order to help facilitate the
in-house conversion.
“On the conversion of our non-time-sensitive data, DCL
again went the extra mile, assisting our programmers, troubleshooting, helping
us understand the software. Much of the extra time they spent with us was
off-budget, and they did it anyway. This earned a lot of points with our
people,” Ferrara said.
Post Project Reflections
Today the 25,000 critical pages are in use in LMSS’s
Missile Assembly Plan (MAP) program, and products are being built with
them. These pages are also being
prepared for use in Interactive Electronic Technical Manuals (IETMs).
The 225,000 pages of archived data have also been
converted.
“We have nothing but positive things to say about Data
Conversion Laboratory,” Ferrara concluded. “DCL maintained their schedule
and their budget while giving us superior service—and a superior
product—above and beyond the call. This project helped launch Lockheed Martin
and our U.S. Navy customer into the new millennium, and DCL was absolutely key
in launching the project.”
