Issues and Challenges in Existing Re-engineering Methodologies of Object Oriented Systems

Software products in use today need to be updated frequently to stay alive in the market and meet the increasing needs of their customers. In general, a software system experience constant modification and extension in its life cycle. Most enhancements are performed based on developers’ knowledge and experience using ad-hoc approaches. Re-engineering a software system is an economical way to provide a much-needed boost to alter the current software. In this paper, researchers examine the existing methodologies in terms of their inherent quality attributes like flexibility, simplicity, and effectiveness. This study also intends to address the limitations that software engineering teams are currently facing when they do not use a specific methodology in executing the re-engineering process.
