Abstract:This paper presents the results of a user centered systems analysis of a proposed software system, the North Dakota Intermodal Management System. The study surveyed and evaluated several object-oriented analysis methods to select the one that best supports user centered development. This examination determined that Jacobson's Use Case Driven Approach best meets that criterion. The study continued the analysis with an initial application of Jacobson's methodology to the software. This part of the analysis included the identification of high level use cases and the object specification of an example use case. In doing so, the paper augmented Jacobson's methodology by introducing a priority ranking of the primary actors in the software system and by applying user centered design principles and guidelines to the development of a system prototype. The paper concluded by presenting an analysis of alternative software development environments for implementing the software. These alternatives were evaluated and presented to the agency considering system implementation. The analysis examined the potential functionality for each alternative and compared each alternative with the other possible software development environments.
