A visualization tool for requirements specification

Abstract

Specifying the requirements to be met by a new system is a fundamental activity in the early stage of the system development life cycle. Any errors occur at this point will affect the implementation phase of the system. The specification of requirements need not be a very large document or too technical but it must contain sufficient information to enable stakeholders understand the requirements of the system to be developed and respond to it. As an alternative for better understanding of the requirements, a requirements visualization tool, ReVis is proposed and developed. The tool is mainly developed to organize, visualize and verify the requirements gathered in requirements elicitation stage based on stakeholders. Node Link Diagram, TreeMaps, Dynamic Queries, Focus + Context, Overview + Detail, Colour, Zooming, Highlighting are the visualization techniques applied in this tool.
