Doskey, Steven Craig – ProQuest LLC, 2014
This research presents an innovative means of gauging Systems Engineering effectiveness through a Systems Engineering Relative Effectiveness Index (SE REI) model. The SE REI model uses a Bayesian Belief Network to map causal relationships in government acquisitions of Complex Information Systems (CIS), enabling practitioners to identify and…

Tomasino, Arthur P. – ProQuest LLC, 2013
In spite of the best efforts of researchers and practitioners, Information Systems (IS) developers are having problems "getting it right". IS developments are challenged by the emergence of unanticipated IS characteristics undermining managers ability to predict and manage IS change. Because IS are complex, development formulas, best…

Mir, Masood Saleem – ProQuest LLC, 2012
The interdisciplinary nature of "Systems Engineering" (SE), having "stakeholders" from diverse domains with orthogonal facets, and need to consider all stages of "lifecycle" of system during conception, can benefit tremendously by employing "Knowledge Engineering" (KE) to achieve semantic agreement among all…

Tran, Kiet T. – ProQuest LLC, 2012
This study examined the relationship between information technology (IT) governance and software reuse success. Software reuse has been mostly an IT problem but rarely a business one. Studies in software reuse are abundant; however, to date, none has a deep appreciation of IT governance. This study demonstrated that IT governance had a positive…

Choi, Daeheon – ProQuest LLC, 2012
Over the past decades, network technologies across supply chains have been introduced and promoted with the premised benefits for all participants. However industry experience with an adoption process of some technology suggests that some firms have a great amount of uncertainty in estimating the benefits of its adoption. This uncertainty will…

Elhindi, Mohamed A. – ProQuest LLC, 2010
Historically, managing access to information systems (ISs) required direct interaction with a limited number of users. Increasingly, managing access involves handling an increased numbers of internal and external students, faculty, and staff as well as partners such as workforce development centers, the U.S. Department of Education, and the…

Hensley, Kendra – ProQuest LLC, 2011
Total quality management based governance models tend to focus on incremental improvements within the boundaries of a single organization. This may limit the benefits of information technology because they are not complex enough to address business or performance problems that extend beyond the boundaries of a single organization. The research…

Mattia, Angela Marie – ProQuest LLC, 2009
User participation and its relationship to system success have been discussed in the information systems (IS) literature from many theoretical and practical perspectives. In reality, most of this discussion is grounded in empirical research that has yielded mixed results on the importance of user participation and its relationship to system…
