Techrisk –a Decisional Framework to Measure Technical Dimensions of Legacy Application for Rejuvenation through Reengineering

Competitive business environment wants to modernize existing legacy system in to self-adaptive ones. A variety of options are available to renovate legacy system in to more contemporary system. Recently the phenomenon of “software reengineering “, a methodology to allow old ways of thinking to be replaced with new, fresh approaches to increase productivity and quality of system, has been reported. However evolving legacy system through reengineering is a risky and error –prone task due to extensive changes it requires in the majority of cases. Therefore cost effective reengineering requires identifying and measuring impact of system, managerial and technical risk. We present a technical domain framework TechRisk to identify and measure quality and functional dimensions of legacy system. The objective is to identify those risk factors of technical domain which are critical to the success of reengineering. Proposed decision driven framework TechRisk provide support to identify and eliminate the highest impact risks in the software reengineering process and help to create a successful reengineering solution.
