Value-Added Prototyping: Visualizing GIS Requirements via Multimedia Technologies Author: Avis L. Webster 3 Pooks Hill Rd. Phone: (301)897-9079 Developing a successful GIS depends on comprehensively defining user requirements and translating the requirements into GIS functional capabilities. Parameters of confidence for requirements capture include requirements consistency, completeness, and the visualization of system behaviors. A successful requirements assessment provides a foundation to predict design performance, identify risks related to design, and propose corrective action when design flaws are detected. Prototyping has long been recognized as an effective tool for requirements definition. This paper examines the use of multimedia technologies applied to prototyping for requirements definition and explores the use of UML and object-oriented design methods in developing multimedia prototypes. |
