A Method To Define Requirements For System Of Systems, Randy Gene Walker

Engineering Management & Systems Engineering Theses & Dissertations

The purpose of this research was to develop and apply a systems-based method for defining System of Systems (SoS) requirements using an inductive research design. Just as traditional Systems Engineering (TSE) includes a requirements definition phase, so too does System of Systems Engineering (SoSE); only with a wider, more over- arching, systemic perspective. TSE addresses the design and development of a single system with generally a very specific functional purpose enabled by any number of subcomponents. SoSE however, addresses the design and development of a large, complex system to meet a wide range of functional purposes enabled by any number …

Systems Theory Based Framework For Competency Models, Joseph M. Bradley

Engineering Management & Systems Engineering Theses & Dissertations

The purpose of this research was to develop and apply a systems theoretic framework for design, analysis and transformation of competency models using an inductive research design. This research examines the origins and development of competency models from a systems theoretic perspective. Competency models have been largely developed by a comparative method first proposed by McClelland, or the use of Delphi method survey techniques. The assumption that a population containing an exemplar and fully successful members would enable population of a holistic competency model has reported numerous failures. Similarly, reporting on the use of Delphi methods has focused on attempting …

A Systems-Based Framework For The Assessment Of Performance Measurement System Implementations In R&D Organizations, Kenneth S. Baggett Jr.

Engineering Management & Systems Engineering Theses & Dissertations

Performance measurement is utilized by organizations in all industries, including research and development (R&D). Measures are developed, data are collected, and the measurement results are used to drive the organization. The implicit hope is, of course, that the measures drive the organization to improve. However, literature identifies high failure rates directly related to performance measurement system (PMS) implementations. Establishing the fundamental operational characteristics associated with successful PMSs would provide a significant contribution towards the establishment of PMS assessment criteria. This research addresses this gap through the use of a grounded theory method employed to identify these operational characteristics, assesses the …

Assessing The Impact Of Electronic Health Record Systems Implementation On Hospital Patient Perceptions Of Care, Katherine Sofia Palacio Salgar

Engineering Management & Systems Engineering Theses & Dissertations

The delivery of health care services has been impacted by advances in Knowledge Management Information Systems (KMIS) and Information Technology (IT). The literature reveals that Electronic Health Records Systems (EHRs) are a comprehensive KMIS. There is a wide recognition in the body of knowledge that demonstrates the potential of EHRs to transform all aspects of health care services and, in consequence, the performance of Health Care Delivery Organizations (HCDO). Authors of published research also agree that there is a need for more empirical contributions that demonstrate the impact of EHRs upon HCDO. It is argued that in most cases, studies …

The Relationship Among Hfacs Levels And Analysis Of Human Factors In Unmanned And Manned Air Vehicles, Veysel Yesilbas

Engineering Management & Systems Engineering Theses & Dissertations

This dissertation analyzes the structural relationships among the Human Factors Accident Classification System levels for unmanned air vehicle and manned air vehicle accidents and the common relationships between unmanned air vehicle and manned air vehicle accident causes. The study acquired DOD HFACS accident classification data from 347 United States Air Force Class A accident reports for the years between 2000 and 2013.

The dissertation utilized a set of analysis that is considered to contribute substantially to the respective domain of the study. The correlations found among categorical levels were applied to HFACS taxonomy based on the Reason Model via path …

An Instrument To Assess Individual Capacity For System Thinking, Ra'ed M. Jaradat

Engineering Management & Systems Engineering Theses & Dissertations

The purpose of this research was to develop and deploy a new systems thinking instrument to assess individual capacity for systems thinking using an inductive research design. While technology has been increasing exponentially, the corresponding methods to harness those technological advances, and the problems they have spawned, is lagging. While there is a broad collection of systems based methods, techniques, technologies, and tools that can be used in dealing with complex problems, these are predicated on an individual's capacity for engaging a level of systems thinking commensurate with their effective, deployment. Research based methods to determine individual capacity for systems …
