Decision driven risk measurement model to quantify reengineering risk in stakeholder perspective of legacy system

In today´s risk sensitive business environment, software has become the most valuable asset for organization. The success of any organization severely depends on the quality of their legacy systems so it is important to put more research effort in obtaining a better understanding of legacy system problems and their solutions. During the last several years, reengineering gained increasing interest. However, it incurs some risk overhead due to widespread deviations it requires in majority of cases. Effective reengineering clearly indicates the need for resolution of reengineering risk. We present a risk measurement model to measure comprehensive impact of different risk components materialize in stakeholder perspective of legacy system. The result is used to take decision about evolution of legacy system.
