MODULAR OPEN SYSTEMS APPROACH (MOSA).

MOSA HAS BEEN FEDERAL POLICY REQUIREMENT SINCE 2021.

TITLE 10 U.S.C. 4401(A) STATES,

“ALL MAJOR DEFENSE ACQUISITION PROGRAMS (MDAP) ARE TO BE DESIGNED AND DEVELOPED USING A MODULAR OPEN SYSTEMS APPROACH-

Employs a modular design that uses modular system interfaces between major systems, major system components and modular systems;
Is subjected to verification to ensure that relevant modular system interfaces comply with, if available and suitable, widely supported and consensus-based standards; or are delivered pursuant to the requirements established in FY21 National Defense Authorization Act Section 804 (a)(2)(B)”

WHAT MOSA ACTUALLY REQUIRES.

DEFENSE PROGRAMS OPERATING UNDER MOSA POLICY MUST DEMONSTRATE COMPLIANCE WITH MULTIPLE OVERLAPPING MILITARY STANDARDS SIMULTANEOUSLY, FOR EXAMPLE:

MIL-STD-1472H (HUMAN ENGINEERING)

FACE TECHNICAL STANDARD

THE COMPLIANCE BURDEN IS DOCUMENTATION-HEAVY, AUDIT-FACING, AND ALMOST ALWAYS UNDER-RESOURCED.

STANDARD PROGRAM ENGINEERING TEAMS ARE EQUIPPED TO BUILD THE SYSTEM.

THEY ARE RARELY EQUIPPED TO PROVE IT MEETS EVERY STANDARD AT THE SAME TIME.

THAT IS THE GAP SEDAC FILLS.

SEDAC MIL-STD SYSML TEMPLATE SYSTEM.

SEDAC PATENT-PENDING SYSTEM DECOMPOSES ANY U.S. MILITARY STANDARD INTO A STRUCTURED, INTEROPERABLE SYSML MODEL COMPONENT.

COMPLETE WORKFLOW FROM RAW STANDARDS DOCUMENT TO PRODUCTION-READY ARCHITECTURE FEATURING:

UNIQUE NAMING CONVENTION: MILSTD[####A]_ PREFIX ON EVERY REQUIREMENT — NO ID COLLISION ACROSS 100+ CONCURRENT STANDARDS

NAVIGATION LANDING PAGE: CONTENT DIAGRAM AS TOP-LEVEL MODEL ENTRY POINT — ACCESSIBLE TO NON-MODELERS

PACKAGE STRUCTURE: EACH MIL-STD SECTION MAPS TO A STRUCTURED PACKAGE WITH SECTION LANDING PAGE

REQUIREMENT HIERARCHY: PARENT-CHILD ELEMENTS MATCH MIL-STD SECTION NUMBERING EXACTLY — FULL AUDIT TRACEABILITY

NON-MODELER UI:PMS, COS, AND T&E CAN VERIFY MOSA COMPLIANCE WITHOUT SYSML EXPERTISE

ALL DELIVERABLES ARE GOVERNMENT SPONSOR OWNED. TEMPLATE PACKAGE LICENSING IS TRANSFERABLE ACROSS PROGRAMS AND CONTRACTORS WITHOUT RENEGOTIATION.

READY TO GET AHEAD OF YOUR CDRLS?

SEDAC works best when engaged early — before the DID list is finalized, before the program office is locked in. Let's talk about where your next CDRL burden is coming from.
