The modeling technique for Software Reliability is reaching its prosperity. Software reliability growth models have been used extensively for closed source software. The design and development of Open Source Software (OSS) is different from closed source software. The authors observed some basic characteristics for open source software like more instructions execution and code coverage taking place with respect to time, release early, release often, frequent addition of patches, heterogeneity in fault density and effort expenditure, frequent release activities seem to have changed the bug dynamics significantly and bug reporting on bug tracking system drastically increases and decreases.
