Modular Design


Modular Design 

Modular design allows for modifications to systems, recombination of existing capabilities and upgrade of system elements, to enable competition, innovation, rapidly responding to a changing environment. Designing for modularity is a technical principle for implementing a Modular Open Systems Approach (MOSA) and is a complementary piece to the open system practices in contracting. The major tenet of a modular design strategy is to develop loosely coupled modules, where modules can be decoupled, separated, or even rearranged in a major system platform and major system components developed under the program, as well as major system components developed outside the program that will be integrated into the major defense acquisition program. When designing for modularity, the system should be appropriately partitioned into discrete, scalable, self-contained functional elements by decomposing and decoupling the functions of a system. This functional partitioning results in elements that can now be composed into modules that can be reconfigured or even replaced.
