Subject: Instructions for Modular Open Systems Approach (MOSA) Implementation.OFFICE OF THE UNDER SECRETARY OF DEFENSE 3000 DEFENSE PENTAGON WASHINGTON, D.C. 20301-3000 JUL 07, 2004 MEMORANDUM FOR SEE DISTRIBUTION SUBJECT: Instructions for Modular Open Systems Approach (MOSA MOSA Modular Open Systems Approach (US DoD acquisition) MOSA Ministry of Social Affairs (Lebanon) MOSA MOtoSAldatrici (Italy) MOSA Monmouth Ocean Soccer Association ) Implementation [ILLUSTRATION OMITTED] A Modular Open Systems Approach (MOSA) is a means to assess and implement, when feasible, widely supported commercial interface standards in developing systems using modular design In the context of systems engineering, modular design — or "modularity in design" — is an approach aiming to subdivide a system into smaller parts (modules) that can be independently created and then used in different systems to drive multiple functionalities. concepts. It is an integral part of the toolset that will help DoD achieve its goal of providing the joint combat capabilities required in the 21st century, including supporting and evolving these capabilities over their total life cycle. The USD USD In currencies, this is the abbreviation for the U.S. Dollar. Notes: The currency market, also known as the Foreign Exchange market, is the largest financial market in the world, with a daily average volume of over US $1 trillion. (AT & L) memorandum, dated April 5, 2004, states: "commencing 1 Oct 04 all programs subject to milestone review shall brief their program's MOSA implementation status to the Milestone Decision Authority (MDA (1) (Monochrome Display Adapter) The first IBM PC monochrome video display standard for text. Due to its lack of graphics, MDA cards were often replaced with Hercules cards, which provided both text and graphics. See PC display modes and Hercules Graphics. ) for compliance." The purpose of this memorandum is to describe how this requirement will be addressed for systems and systems-of-systems in the formal acquisition process. Given the enabling relationship of a modular open systems approach to evolutionary acquisition, DoD acquisition programs should address Modular Open Systems Approach (MOSA) early in their program and acquisition planning, and should discuss MOSA implementation in the context of their overall Acquisition Strategy and to the extent feasible in the Technology Development Strategy. MOSA implementation issues In the Business world, companies frequently set-up a connection between which they transfer data. When the connection is being set-up, it is referred to as implementation. When issues occur during this phase, they are known as implementation issues. should be identified and addressed via the IPT IPT - IP Telephony process and presented as issues to the MDA only when unresolved at a lower level. The Open Systems Joint Task Force (OSJTF OSJTF Open Systems Joint Task Force ) is my lead for MOSA and has developed the Program Assessment and Rating Tool (PART) for your use in conducting your internal MOSA implementation assessments. Program Managers should either use the PART, or an equivalent method of assessment, to generate objective data on the success of their MOSA implementation. The OSJTF Program Managers MOSA guide and PART are available at http://www.acq.osd.mil/osjtf/html/mosa_assessment.html. Additionally, pertinent MOSA and PART information will be provided in the next update to the DoD Acquisition Guidebook. The OSJTF is responsible for the development and oversight of MOSA policy to include emerging system-of-systems policy to develop open integrated architectures for capability areas. If you have any questions or need further guidance on required reporting, my point of contact is COL Ken Flowers Ken Flower served as the head of Rhodesia's and later Zimbabwe's Central Intelligence Organisation. He has been tied to the creation of RENAMO, a militant anti-Communist organization in Mozambique. , Director, OSJTF.
