VISUAL-K: A PROTOTYPE FOR A VISUALIZATION TOOL MODELING GOAL-ORIENTED RE METHODOLOGY KAOS

摘要

This paper presents a requirements analysis tool Visual-K, which supports visualization for goal-oriented RE methodology KAOS. Goal-oriented requirements analysis is one of the most important requirements analysis approaches which considers needs as goals a system must achieve. It analyzes requirements in terms of achieving goals why and how. However goal-oriented requirements analysis models become larger and more complicated as the system becomes large-scale and common requirements or functions are decentralized. Therefore we apply information visualization to goal-oriented requirements modeling and develop Visual-K to improve visibility and operability. Visual-K can focus on and emphasize remarkable items. It can display before and after changes of requirements analysis models continuously by performing animated transitions between views.
