The Open Source Maturity Model (OMM) is a methodology for assessing Free/Libre Open Source Software (FLOSS) and more specifically the FLOSS development process.
This methodology is released under the Creative Commons license.
OMM may help in building trust in the development process of companies using or producing FLOSS.
[1][2] OMM objectives are to provide FLOSS communities a basis for developing products efficiently and making their products trustworthy for the potential customers, and also for integrating companies and to provide FLOSS integrators a basis for evaluating the processes used by the FLOSS communities.
While attempting to develop such a model, a few basic facts had been considered: The OMM model is now tested and validated in real FLOSS projects[4] that are led by FLOSS communities or by software development companies.
