Abstract

This report presents an experiment comparing two lightweight methodologies. The objective of the experiment was to assess extreme programming seen as a design-less process and an agile methodology based on design. The experiment ran in a real environment. Twenty teams produced 20 systems, from scratch to the final product, in a period of one semester. They attended 4 clients. The factors of the experiment were time, quality and size. The systems written by extreme programming teams were slightly better than "agile design-based" teams. This findings show that a mature/improved version of extreme programming should be much more successful.
