Comparison of Six Software Engineering Models

Software systems and their applications come and go through a series of passages of time that account for their inception, initial development, techniques, productive operation, upkeep and retirement from one generation to another generation. This paper article categorizes in different ways and examines various numbers of methods and techniques for describing and modeling how software systems are developed. During software development process, software companies and industries are exposed to risks (unwanted events and causes) which leads to economic and competitive loss. Risk management technique and various methods are being used to minimize the loss in software systems and projects. Different software process improvement models are used to include risk management among their rules, methods and guidelines. The main purpose and goal of this paper is to emphasize on evaluation and analyzing how the models can be used as accordance with the comparison based study.
