Layered approach of analysing OSS and risk management

In a simple language a software product where in the availability of the source code of the software is available in the public domain is referred to as an Open Source Software (OSS). Some of the models proposed in the papers published in different international journals are discussed in this paper. Some statistical data concerning open source software and the related shortcomings have also been covered. A detailed and a thorough comparison of the OSS with the closed source software, their advantages vis-a-vis the disadvantages and certain other aspects have also been carried out making it simpler and understandable by the readers. Quality assurance being of prime importance in any field is a must and like any other feature it gains the same amount of importance in this field as well. This paper facilitates the readers and researchers to understand and analyse OSS with suitable examples.
