Effectively Managing The Air Force Enterprise Architecture, Jamie P. Sharkey Mar 2005

Effectively Managing The Air Force Enterprise Architecture, Jamie P. Sharkey

Theses and Dissertations

The Air Force is developing and implementing an enterprise architecture to meet the Clinger-Cohen Act's requirement that all federal agencies use an architecture to guide their information technology (IT) investments. However, this act does not provide guidance on how to effectively manage an enterprise architecture. Prior research applied maturity models and competency stages to manage an enterprise architecture by defining layers of enterprise architecture management maturity. However, these efforts tend to view enterprise architecture development as a one-time planning process rather than an iterative progression. Enterprise architecture is not a one-time exercise, but rather it is an on-going effort within …

The Application Of Value Focused Thinking To Utilities Privatization Source Selection, J. Heath Duncan Mar 2004

The Application Of Value Focused Thinking To Utilities Privatization Source Selection, J. Heath Duncan

Theses and Dissertations

The Department of Defense's utility systems have suffered from under-funding and lack of technology investment, thereby creating a service gap between these DoD systems and systems operated by commercial providers. In order to overcome this gap and refurbish their systems, the DoD has focused its efforts on privatization of these systems. The utilities privatization decision is extremely vital and permanent and thus warrants backup source selection methodologies. Since awarding contracts in the utilities privatization arena requires a decision considering tradeoffs between multiple competing objectives, a value-focused thinking approach was used to create a structured, standardized value model taking into account …

Recovering From A Stalled Change Initiative: A Case Of Correcting Implementation Mistakes, Ellen L. Dorey

Theses and Dissertations

Amid an age of increasing technology, innovation, and global business competition, there is no question that the pace organizational changes are introduced will increase, as well. With this pace of change, organizational leaders might find themselves short on the time and resources necessary to properly create readiness by utilizing implementation strategies. Frequently, a change initiative that is not introduced properly will meet resistance within the organization. When strong resistance is encountered, the initiative is often abandoned and replaced with some other effort. However, in some situations, the initiative can not be abandoned and implementation must continue. This research effort sought …

Ontological Engineering And Mapping In Multiagent Systems Development, Jonathan M. Dileo Mar 2002

Ontological Engineering And Mapping In Multiagent Systems Development, Jonathan M. Dileo

Theses and Dissertations

Multiagent systems have received much attention in recent years due to their advantages in complex, distributed environments. Previous work at the Air Force Institute of Technology has developed a methodology for analyzing, designing, and developing multiagent systems, called Multiagent Systems Engineering (MaSE). MaSE currently does not address the information domain of the system, which is an integral part of designing proper system execution. This research extends the MaSE methodology to include the use of ontologies for information domain specification. The extensions allow the designer to specify information flow by using objects from the ontology as parameters in agent conversations. The …


A Collaborative Visualization Framework Using Jini™ Technology, Chad M. Harris Mar 2002

A Collaborative Visualization Framework Using Jini™ Technology, Chad M. Harris

Theses and Dissertations

It is difficult to achieve mutual understanding of complex information between individuals that are separated geographically. Two well-known techniques commonly used to deal with this difficultly are collaboration and information visualization. This thesis develops a generic flexible framework that supports both collaboration and information visualization. It introduces the Collaborative Visualization Environment (COVE) framework, which simplifies the development of real-time synchronous multi-user applications by decoupling the elements of collaboration from the application. This allows developers to focus on building applications and leave the difficulties of collaboration (i.e., concurrency controls, user awareness, session management, etc.) to the framework. The framework uses an …
