Assessing Agile Methods: An Empirical Study

Américo SampaioAlexandre M. L. VasconcelosPedro R. Falcone Sampaio

Agile software processes emerged to address the issue of building software on time and withinthe planned budget. To adopt an agile process, it is imperative to analyze and evaluate its effectiveness insupporting high quality software development while complying with stringent time constraints. In thispaper we describe an agile method for Web-based application development (XWebProcess) and anexperiment conducted with a group of forty senior undergraduate students to assess the quality/speedeffectiveness of the proposed method vis-à-vis the effectiveness of Extreme Programming (XP). Theresults have shown that the process proposed is equally agile when compared to XP, moreover, surveysconducted as part of the experiment pointed out that XWebProcess is more suitable to Web developmentin dimensions such as requirements gathering, user interface and navigation design, and software testing,therefore leading to better quality software.
