Risk analysis is the science of risks and their probability & evaluation. Risk analysis includes risk assessment, risk management and risk communication. Risk assessment involves identifying sources of potential harm, assessing the likelihood that harm will occur and the consequences if harm does occur. Risk management evaluates which risks identified in the risk assessment process require management and selects and implements the plans or actions that are required to ensure that those risks are controlled. Risk communication involves an interactive dialogue between stakeholders and risk assessors and risk managers, which actively informs the other processes.
