A Conceptual Knowledge Base Representation for Agile Design of Human-Computer Interface

This article presents some limitations of agile methods and the results of using Scrum in a specific project. It was found that good practices in development of human computer interfaces (HCI) have been left aside in favor of reducing sprint duration. Developers usually "listen to what customers say instead of watching what customers do". This behavior has a tendency to impact negatively the HCI usability. The article also points the common characteristic between agile development and HCI design: the repetition aspect. This article proposes a knowledge base representation of good practices in HCI design. A semantic network is used to represent main concepts in HCI design. The intention is to use this conceptual modeling to implement an expert system to guide agile developers during HCI design.
