Knowledge about the expected impact of different project and technological choices is fundamental for project planning, resource allocation, and quality of the final software product. The latter property, in particular, is essential to gain users’ trust and confidence. In this paper we present some preliminary results about a study we are conducting on open source web applications available in SourceForge. The ultimate goal is providing tools to support project managers and team in making choices that, being all other factors the same, increase the probability of delivering higher quality software products.
