Communication of Design Decisions and Usability Issues: A Protocol Based on Personas and Nielsen's Heuristics

摘要

Although both agile developers and UX designers have a common concern regarding to build software with quality, they usually have different viewpoint of the user experience and usability. We have proposed a protocol in which personas and Nielsen's heuristics were used as a common vocabulary between designers and developers (SCRUM team) for the communication of recommendations and/or design solutions. We have adopted action research to conduct our research, performing a workshop and interviews to study the feasibility of the proposal; and later two case studies to compare and evaluate the use and non-use the protocol. In the final, adding to the case study comparison, we interviewed the SCRUM team who revealed that the protocol improved the understanding of recommendations and the Nielsen's heuristics contributed to objectively communicate the main problems of interaction.
