Abstract
It is difficult to identify risk events correctly. I focus on the following two points as the cause. 1) Difficulty of the common recognition whether to be a risk or not. 2) Risk identification process strongly depends on experience of individuals. This paper proposes the method of risk identification without being influenced by experience. Firstly, I clarify the risk as the object which should be managed in the project in the light of the standard risk model which Smith & Merritt advocates. Secondly, I propose the method of clarifying causal relationship of risks using breakdown structures, after organizing issues when identifying risks. As a result of refining risks in a real project case by using this method, the true risk events were identified and the effective action was planned.
