Investigation of Quality and Functional Risk Issues in Reengineering Process of Legacy Software System

The modern business environment requires organizations to be flexible and open to change if they are to gain and retain their competitive age. Competitive business environment needs to modernize existing legacy system in to self-adaptive ones. Reengineering presents an approach to transfer a legacy system towards an evolvable system. Software reengineering is a leading system evolution technique which helps in effective cost control, quality improvements and time and risk reduction. However successful improvement of legacy system through reengineering requires portfolio analysis of legacy application around various quality and functional parameters some of which includes reliability and modularity of the functions, level of usability and maintainability as well as policy and standards of software architecture and availability of required documents. Portfolio analysis around these parameters will help to examine the legacy application on quality and functional gaps within the application [1]
