Any specific risk will go through the process of identification, analysis, planning, tracking, control and so on, while the risk management activities show continuity, parallelism and iteration in the whole project cycle. For example, while some risks are being tracked, other new risks are identified and analyzed, and the mitigation plan adopted for one risk may generate other new risks in the implementation. As the sources and consequences of project risks change as the project progresses, it is better to take action as early as possible once risks have been identified and evaluated. Continuous tracking of a particular risk will yield more and more relevant information, and the priority of the risk may change. Therefore, for the whole project cycle, it is required to analyze and evaluate the risk set before each stage, so as to select the key and important risks for continuous tracking and management. In the process of risk management, the project team should communicate and feedback information about the status, activities and emerging risks of important risks through formal or informal work channels, and timely document and standardize the management of corresponding work. Continuous risk management process is not only to meet the needs of organizational strategy, also to meet every stage of the total project life cycle risk management goal, such as planning, program, start, and end the requirements to achieve this goal, project risk management process is necessarily to adjust the traditional risk management theory, and the fusion of traditional risk identification, quantification, evaluation, control the whole process of.
