WHY STANDARDIZATION?

Whenever???

Standardization Making a difference
Balkans/Gulf War/IRAQ O Radio communication with
coalition forces and ourselves during the Gulf
Warship to ship, air to land, etc. O
Fratricide combat identification U.S. Plane
shot down British warplane - IRAQ. Friend or Foe
ID. O Commercial handheld radio equipment worked
well limited value due to lack of
standardization. O List of Logistical
Definitions/Key Words in Multinational
Missions.e.g The Chicks are in the
Hutch---- AWACsGulf War O Use of common
fuel/single fuel concept (i.e. jp 8, Aviation
Grade) O Material Handling Equipment (MHE) for
Interoperability- MLRS Pod Unloading O NATO
nations inability to rely on truck/trailer
connection compatibility/interoperability
kingpin (5th wheel) diameter/alignment O Wounded
soldiers carried on stretchers to MEDEVAC
helicopters, but stretchers did not comply with
NATO STANAG 2040 didnt fit.

Standardization Making a difference
Balkans/Gulf War/IRAQ O No standard e-mail
client/server architecture thus requiring
workarounds and additional equipment to
communicate with multinational forces. O NATO
needs to develop a standard digital interface
such that multinational forces can operate on a
single reliable digital interface.UHF/VHF FM
retransmission stations, video teleconferencing,
SATCOM.. O NATO analog switching interface
(STANAG 5040) slow in making connections due to
slow pulse dialing technique versus Dual Tone
Multi-Frequency (DTMF) technique. O Education
that provides confidence that other countries
color-coded tried and proven ammunition will
work in allies weapons. O C3I-Inability to
communicate over secure channels (e.g. difference
among nations in frequency hopping capability) O
Mobile phones widely used, but vulnerability to
intercept not understood O Difficulty in
releasing Intelligence across national
boundaries- especially in any automated fashion

Did Acquisition Reform Help or Hurt? If so,
How????? O Elements of AR O Perry
Directive-June 29, 1994! O SPI for
Contractors/OEMs O SMDs for Component
Manufacturers O QML for Component
Manufacturers O Collaboration-Government and
Industry O Sematech O SRC O STAR
Activities O Government Industry Days O
Commercial Practices-not just products

Acquisition Reform Lessons Learned in
Microcircuit Technology O COTS components are
generally less costly!! O COTS components become
obsolete more quickly. O Commercial practices
yield many benefitscollaboration, joint
development efforts, data sharing, enhanced
capabilitiesrequires discipline and
cooperation. O Commercial practices cause other
problems designs are for specific markets.e.g.
telecom, laptops, servers, consumer where
environments and applications are not so
severe. O Common Parts users have similar
problems and can share data and solutions. O
All parts do not perform the same in different
Users applications O Ability to
transition/upgrade from one node to higher node
is good! O Inability for users to know and
determine differences in performance is often
very significant. IMPLEMENTATION IS OFTEN
DIFFICULT, BUT CAN YIELD BENEFITS!

What about liquid cooling technology? O There is
no ? about the need. O Performance dictates
smaller, more complex, highly reliable,
capability, necessitating near latest generation
electronics. O These electronics generate more
heat but older methodologies of cooling are no
longer adequate. O Liquid (spray) cooling
techniques offer great promise. O There are
however issues to be addressed! O
Standards---specifications---- O
Collaboration? O Costs? Future utility? Can
clients afford? Links to
commercial/consumer use and applications?

Consequences of not collaborating sufficiently
and/or not developing adequate standards up
front or as soon as practical----learned from
the Microcircuit experience O Microcircuit
suppliers exited support of the military market
during the 1990s.Motorola, AMD, Intel,
etc.. O Contractors/OEMs began using
commercial ICs but with uprating practices by
third party test houses or in-house themselves. O
Increasing obsolescence of Mil-Spec components
coupled with increasing use of Commercial parts
not designed for or manufactured for Military
applications created a quagmire of
legal mumbo-jumbo. IC manufacturers sent
letters notifying OEM users of invalidation of
warranty, threats to sue if any catastrophe arose
due to misuse of an IC, and general breakdown in
supplier- customer relationships. O Recent
efforts have brought forth an Integrated
Aerospace Parts Acquisition Strategy (IAPAS) and
an Aerospace Qualified Electronic Component
(AQEC) which is drawing the relationship back
together. O While good, this time-consuming and
difficult task, but must succeed.
11
So, what must be done? O Convert demonstration
projects into viable production products O Seek
complementary uses-customers-applications to
potentially add a volume need to the
equation-------is this possible? O Utilize VITA
and other Associations to develop a Standard
as quickly as practical. Do not allow history
to repeat as in other industries. O
Socialize---- brief everyone you think might be
able to help bring the technology into widespread
use and application. O TALK TO YOUR
CUSTOMERS!!!!!!
