Systems-theoretic process analysis and safety-guided design of military systems
Increasingly complex software enabled systems demand a new hazard analysis and safety-guided design technique in order to meet stringent safety standards and expectations. System Theoretic Process Analysis (STPA) proves to be a powerful tool to identify, describe and help mitigate hazards from the …

Testing and evaluation of military systems in a high stakes environment
Testing is a critical element of systems engineering, as it allows engineers to ensure that products meet specifications before they go into production. The testing literature, however, has been largely theoretical, and is difficult to apply to real world decisions that testers and program managers …

Resource dependencies in parallel development of military systems : a comparison of waterfall and agile development methodologies
The United States Department of Defense has been plagued with failing programs that are over budget, behind schedule, and exhibit poor performance during testing. Once a program has cost, schedule, or capability issues, follow-on development efforts adopt the underlying issues only to reinforce …

Synchronization of system-of-systems interfaces in military satellite communications
Military systems continue to become more complex and nearly all are now part of one or more system of systems (SoS). Military satellite communications programs have expanded over the last decade from three distinct satellite constellations with dedicated ground, ship, and airborne terminals to …

Systems Engineering Processes for the Acquisition of Prognostic and Health Management Systems
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 …
