Application of a Data Visualization Technique Based on Trees to Aid Prioritization of Requirements in Agile Projects

Abstract

The practice of requirements prioritization involves the recovery analysis of each requirement by customers and requirements selection that will be implemented in a specific version of the system. Wrong choices during requirements prioritization may affect the system quality and thus its acceptance by customers. Within this context, some practices of requirements prioritization have been addressed in agile projects to improve the requirements prioritization stage. Among them, there is a practice based on Kano technique, which uses the agile development methodology Scrum in software projects.However, the resulting data from Kano practice produces much textual information, which is difficult to be viewed and analyzed in order to determine the real importance of each requirement. Therefore, this paper proposes a data visualization technique based on "TreeMaps" in order to assist in the viewing results o the Kano technique.
