This paper aims to investigate the possibility of improving uptake of F/OSS artefacts by developing appropriate mechanisms to assure end users that such artefacts will fulfil their needs and satisfy their expectations. The paper considers modelling of the overall F/OSS development process using Soft Systems Methodology [2] and the Unified Modelling Language (UML) [3], and defines particular metrics that can be associated with critical points along this development process. We also describe how such metrics could be used to improve the development process, and demonstrate how automated extraction of such metrics could be employed using F/OSS repositories such as sourceforge.net [4].
