Organizations that wish to modernize their legacy systems, must adopt a financial viable evolution strategy to gratify the needs of modern business environment. There are various options available to modernize legacy system in to more contemporary system. Over the last few years' legacy system reengineering has emerged as a popular system modernization technique. The reengineering generally focuses on the increased productivity and quality of the system. However many of these efforts are often less than successful because they only concentrate on symptoms of software reengineering risk without targeting ischolar_main causes of those risk. A subjective assessment (diagnosis) of software reengineering risk from different domain of legacy system is required to identify the ischolar_main causes of those risks. The goal of this paper is to highlight ischolar_main causes of software reengineering risk. We proposed a ischolar_main cause analysis model RCause that classify ischolar_main causes of software reengineering risk in to three distinctive but connected areas of interest i.e. system domain, managerial domain and technical domain.
