Background: William Fine's method is one of risk assessment that has a cost justification index for the control measures. Therefore, in this study, we examined how to use this method in risk assessment studies in Iran. The present study aims at providing a better understanding of the benefits and limitations of this method and to provide a platform for improving the cost factor table in this method. Methods: In this study, based on PRISMA, scientific articles were searched from databases. The purpose of the study was to evaluate the risk using the William Fine's method, so general keywords including safety, risk assessment, William Fine were searched in Persian databases and their English equivalents in English databases. The results were analyzed qualitatively. Results: A total of 357 related articles, finally 30 qualified studies were included in the systematic review process. Investigation of studies showed that in many of them, the cost justification index of control measures has not been calculated and only William Fine's method has been used to rank the risk score. This index has been calculated only in a limited number of studies. Conclusion: William Fine's method has a high score in evaluating corrective strategies in economics and engineering, due to utilizing the cost justification index. One of the strengths of William Fine's method is the cost justification index. It seems that one of the reasons for not estimating the J index in the studies is that the numbers provided in the cost index table are outdated.
