Analysis and comparison of DoDAF and ZACHMAN framework for use as the architecture for the United States Coast Guard's maritime patrol (WPC)
(Monterey, CA; Naval Postgraduate School, 2005-09) Griffin, Latan K.; Osmundson, John; Systems Engineering (SE); Graduate School of Engineering and Applied Science (GSEAS); Naval Postgraduate School (U.S.); Carter, Joy B.
WMSM ) and Maritime Patrol Coastal (WPC). The System Architecture Description Document (SADD), which describes architectural framework that is used to establish the rules, guidance, and product descriptions for developing and presenting architecture descriptions that ensure a common denominator for understanding, comparing, and integrating architectures needs to be written for the WPC. The SADD has been written, established and contractual agreed upon for both the Large and Medium Cutters. However, their missions dictate that they have littoral capabilities and the capacity to conduct missions with naval vessels; therefore the C4ISR architecture was chosen for their SADD as it fits their mission statements. The mission of the WPC is of a different nature. It is not expected to carry out the same functions as the larger cutters and its capabilities will be more of a littoral function. Therefore the application of its architectural Framework will enable architectures to contribute most effectively to building an interoperable and cost effective system subject to the needs of the WPC mission. This thesis proposes to compare two different architectural frameworks for use by the WPCâ s SADD: 1) DoD Architecture Framework and 2) Zachman Architecture Framework. The thesis will compare and recommend the architectural framework that will at most enhance the mission statement set forth by the Original Requirements Document (ORD) of the WPC.
Commercial off The Shelf (COTS) security issues and approaches
(Monterey, CA; Naval Postgraduate School, 2006-09) Doan, Dung.; Osmundson, John; Systems Engineering (SE); Graduate School of Engineering and Applied Science (GSEAS); Naval Postgraduate School (U.S.); Kochmann, Michael
Custom built products do not always meet the new Department of Defense (DoD) requirements. Their high cost and lengthy development cycle does not suit the Information Age where communication information and technology develop rapidly. To adapt to this new environment, Commercial off The Shelf (COTS) software products have become the core for Military systems. This is the only way to approach the readiness requirements for armed forces. Like any other products, COTS software brings a lot of advantages but also carries side effects for military systems. One of the most serious issues for military use of a COTS software product is its security. This thesis provides an analysis of approaches to identify the security vulnerabilities and recommends an acquisition approach to minimize the issue. It is not the intent of this thesis to find a universal approach to solve the security issue of COTS products.

The Carrier Readiness Team realizing the vision of the Naval Aviation Enterprise
(Monterey, California. Naval Postgraduate School, 2009-03) LeFon, Carroll F.; Calvano, Charles; Systems Engineering (SE); Graduate School of Engineering and Applied Science (GSEAS); Systems Engineering Management; Roberts, Ben
Naval aviation is a large and complex operation, with multiple stakeholders and an ingrained tension between generating combat readiness for current operations and procurement funds for future capabilities. Naval aviation leadership has developed an enterprise approach to managing these often competing requirements that uses modern business process tools under the fundamental principle of alignment. This process showed remarkable results at the factory-level, with production efforts generating significant savings and process efficiencies. From that initial success, the enterprise model was enlarged to overall management of aircraft flight hours, supply parts, personnel and production of replacement airframes. It was further enlarged to encompass the aircraft carrier fleet. This thesis examines the environment that drove the need to employ an enterprise construct, comparing it to the systems engineering approach used to bring new material solutions from concept of operations, to development and sustainment over the product lifecycles. It analyzes the tools and processes used, the benefits gained and the costs of executing under the enterprise management scheme. It analyzes how the Naval Aviation Enterprise model has been exported to other warfighting enterprises and the Navy generally. It concludes that enterprise alignment using modern business process tools indeed provides naval leadership with powerful leverage to generate combat readiness at reduced cost, now and in the future. It also concludes that further work remains to be done to ensure that an ingrained culture of consumption becomes cost-aware, and that real alignment of missions, functions and tasks must be undertaken to ensure that "quick wins" translate eventually into sustained, strategic change management.

NPS TINYSCOPE program management
(Monterey, California. Naval Postgraduate School, 2010-09) Turner, Christopher Gordon.; Romano, Marcello; Newman, James Hansen; Systems Engineering (SE); Graduate School of Engineering and Applied Science (GSEAS); Space Systems Operations
This master's thesis introduces the program management and concept of operations of the TINYSCOPE Program. TINYSCOPE is a 6U CubeSat designed as a low-cost and easily replaceable imaging spacecraft that can produce tactically relevant imagery data. Tactical requirements in this context would emphasize "good enough" image resolution with a rapid-response tasking loop and high revisit rate. The TINYSCOPE project intends to demonstrate the utility of small, risk tolerant spacecraft for tactical imagery. The program management section of the thesis discusses the relationships of cost, performance, risk, and schedule and the impact of each on the program. The program's successes and failures are examined to glean lessons for future program managers of university projects. The remainder of the thesis develops a comprehensive concept of operations for the prototype spacecraft. Areas of discussion include overviews of the ground, space and launch segments of the mission architecture, and proposed conduct of operations for those segments. Finally, relevant program management and systems engineering documentation are presented as appendices.
Three Approaches to Space Systems Acquisitions and their Application to the Defense Departments Weather Satellite Program
(Monterey, California. Naval Postgraduate School, 2012-03) Phillips, Wellington V.G.; Langford, Gary; Systems Engineering (SE); Graduate School of Engineering and Applied Science (GSEAS); Systems Engineering Management; Bonesteele, Raymond
For more than a half century, the United States government has been acquiring and launching satellites. However, throughout these years, there has been a shift in the space systems acquisitions model, from acquiring greater quantities but less complex satellites, to fewer quantities but drastically more complex individualized satellites. Within the past two decades, when a new satellite was to be built, whether as part of an existing generation of satellites or the first of its kind, it appeared that the acquisition process starts over from the beginning as if it was the first time building a satellite. This shift in the model has resulted in these individualized systems being extremely costly and taking a long time to be produced. The acquisition of the Defense Departments Weather Satellites is one such example. This author asserts that effective systems acquisition requires a system engineering-inspired approach. The result of systems engineering guidance is to synthesize general principles from case studies. Therefore, this thesis researched the history of some Air Force Space acquisitions programs, current factors affecting the way systems are acquired, and new approaches (Fast, Inexpensive, Simple, Tiny [FIST], and Evolutionary Acquisition for Space Efficiency [EASE]) that are intended to remedy the aforementioned problems. In addition, Toyotas process for producing new vehicles models was also reviewed. These three approaches were then applied to the Defense Departments Weather Satellite program to develop recommendations for its follow-on programs acquisition strategy.
Systems architecting approach to towing and salvage ship recapitalization
(Monterey, California. Naval Postgraduate School, 2008-06) Southworth, George T.; Whitcomb, Clifford; Systems Engineering (SE); Graduate School of Engineering and Applied Science (GSEAS); Systems Engineering (SE); Papoulias, Fotis.
Four salvage ships and four ocean-going towing ships are maintained and operated by the Military Sealift Command (MSC) for the U.S. Navy. In 2019, the first T-ATF ships will reach the end of their 40-year life expectancy. The program manager for these vessels has a set of top-level performance characteristics that are deemed as desirable requirements for a new ship class, encapsulating both legacy ship class capabilities. The DoD has shifted defense planning from the specific service requirements generated system (RGS) acquisition to the Joint Capabilities Integration and Development System (JCIDS) approach that focuses more on how adversaries fight rather than whom they are fighting. This thesis explores how to use systems architecting to incorporate the capabilities derived from strategic guidance into a Department of Defense Architecture Framework (DODAF) product. The design tool, CORE, is used to explain the architecting methodology and produce DODAF v1.5 system models for decision making and acquisition requirement generation.
Systems Engineering Processes for the Acquisition of Prognostic and Health Management Systems
(Monterey, California. Naval Postgraduate School, 2012-09) Begin, Michael P.; Millar, Richard; Systems Engineering (SE); Graduate School of Engineering and Applied Science (GSEAS); Systems Engineering Management; Mayhew, Eric
Prognostic and Health Management (PHM) systems often experience delayed fielding and lengthened maturation cycles due to their relative immaturity and the fact that they are regarded as non-flight critical systems. The national fiscal crisis and rising debt of the U.S. have each placed increased scrutiny on military systems acquisition and procurement practices. The Defense Department is pushing for greater emphasis on fundamental systems engineering practices earlier in the acquisition phase, with the expectation of fewer schedule slips and budget overruns. The acquisition of PHM systems could also benefit from increased systems engineering rigor early in their development. A 2007 directive from the DoD states that PHM systems be implemented into current weapon systems equipment, and materiel sustainment programs where technically feasible and beneficial. This research examines the definition of PHM requirements and a method for developing a solution neutral architecture for PHM systems. The thesis also identifies software development practices and acquisition processes for military propulsion PHM systems. The conclusion of this research is that the Defense Department can deliver the warfighter a capable PHM system on-time and within budget through the establishment of better procurement and systems engineering practices.
An investigation of network enterprise risk management techniques to support military net-centric operations
(Monterey, California. Naval Postgraduate School, 2009-09) Teply, John F.; Kujawski, Edouard; Systems Engineering (SE); Graduate School of Engineering and Applied Science (GSEAS); Systems Engineering Management; Johnson, Jean
lement of risk management processes, is evaluating the network for resiliency; the ability to return to normal in time to prevent the compromise of a mission. The contention is that risk management planning must include planning for network survivability and resiliency. Selected elementary network architectures are analyzed for attributes of the architectures that promote information assurance qualities of confidentiality, integrity, and availability. Finally, recommendations are made on applying important elements of network risk management into the conceptual architecture of a global network.
