(DAU Glossary)
MOSA, which is now the DoD's preferred
method for implementation of
open systems, is also required by United
States law. Title 10 U.S.C. 2446a.(b),
8
Sec 805 states that all major defense
acquisition programs (MDAP) are to be
designed and developed using a MOSA.
Major defense programs must
employ a modular design that uses
major system interfaces between a

major system platform and a major
system component, between major
system components, or between major
system platforms. The modular design
must be subjected to verification to
ensure major system interfaces comply
with, if available and suitable, widely
supported and consensus-based standards.
Adherence with MOSA directives
results in a system architecture
that allows severable major system
components at the appropriate level to
be incrementally added, removed, or
replaced throughout the life cycle of a
major system platform to afford opportunities
for enhanced competition and
innovation.
DoD is now actively pursuing MOSA
in the life cycle activities of its Major
Defense Acquisition Programs and
Major Automated Information Systems,
to keep pace with the rapid evolution
in technology and threats that require
faster cycle time for fielding and modifying
warfighting capabilities.
A key enabler for MOSA is the adoption
of an open business model, which
requires doing business in a transparent
manner and leveraging the collabAerospace
