Abstract
To control project risks, risk identification process is first executed to develop the list of identified risks. At that time, it is unexpectedly difficult to identify risks appropriately. In particular, when multiple persons are involved in risk identification process, same risks are often listed many times because the same risks are expressed differently by different person. Also, there are often times when items listed as risks are actually problems or issues. The reason for these results seems to be the gap of risk recognition by each person. This paper discuss the standardized risk expression, with reference to some existing risk models, which will minimize the recognition gap.
