The Open Source Maturity Model (OMM) is a methodology for assessing Free/Libre Open Source Software (FLOSS) and more specifically the FLOSS development process.
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.
OMM is interchangeably referred to as model and methodology.
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.
