Achieving Usability: Looking for Connections between User-Centred Design Practices and Resultant Usability Metrics in Agile Software Development

Abstract

This article searches for correlations between the practices of usability professionals from software development teams and the resulting usability of the system they are working on. After reviewing the literature of the past decade, we can conclude that most researchers try to achieve better usability with process proposals, but measurements focus on perceived usability. The level of involvement of users in the requirements capture phase is unclear. There is a trend to reduce costs of usability engineering, either by choosing more lightweight and informal methods or by trying to substitute user involvement. Looking at decade's worth of 452 articles about "agile AND usability" in Scopus, we selected 133 which deal with the integration of usability, UX and User Centred Design practices and Agile development.
