Using a Modular Open Systems Approach in Defense Acquisitions: Implications for the Contracting

This research explores the use of the modular open systems approach (MOSA) as a method for implementing an evolutionary acquisition strategy as well as the implications of using such an approach on the contracting process. A background on evolutionary acquisition is provided highlighting the benefit of rapid development and production of weapon systems incrementally, with each increment providing an increasing level of capability. The modular open systems approach (MOSA) is identified as an enabler for the evolutionary acquisition strategy, and a brief discussion on open systems is provided. The contractual implications of using a modular open systems approach is then discussed, focusing on each of the six phases of the procurement process. Examples of MOSAspecific contracting activities and documents are taken from recent US Navy weapons systems acquisition programs such as the Navy’s Common Enterprise Display System (CEDS) program, Anti-Submarine Warfare (ASW)/Undersea Warfare (USW) Test Information Management System program, Multi-mission Maritime Aircraft (MMA) program, Littoral Combat Ship (LCS) Mission Package Integrator program, Littoral Combat ship (LCS) Flight 0 Preliminary Design program, and the Navy’s Mobile User Objective System (MUOS) program. The research will then conclude with the identification of characteristics of a successful MOSA program procurement and resulting contract.
