By developing appropriate mechanisms to signal quality to endusers in simple, easy to understand terms, assuring them that the produced artefacts will satisfy their needs and requirements, the community could overcome this issue and encourage users to embrace a more open attitude towards the adoption and reliance on F/OSS artefacts. It has been argued that it is necessary to provide metrics for validating the quality of the F/OSS artefacts [1], we suggest that these metrics themselves must follow the free and open source concepts, and be verifiable using tests that are accessible to (or developed by) end users.
