Notice of RetractionMeasuring Risks within a Program Consisting of Multiple Interdependent Projects

Program risk management facilitates a higher-level coordination of interdependencies of risk management activities of all related projects within a program, and supports the optimal risk planning for the program. In addition to the metrics of monitoring individual project risks, risk metrics that monitor the overall program risk level are also essential in program management. As risks are not always independent, this paper proposes several risk metrics to measure risks from program perspective with due considerations of the dependencies between risks, so that better risk management strategies and more effective risk planning decisions can be developed for the program. Through a case study, the metrics are shown useful to monitor the risk trend at the program level, and provide some insight into improving the program risk management practices.
