Problem: Respond to this post. To evaluate risk, there are three different assessment tools that can be used. "The risk assessment tools and frameworks for global supply chains can be divided into three broad categories: decision analysis, case study, and perception based." (Manuj, I., & Mentzer, J. T. 2008) Decision analysis can be used to define decisions, and since the possible outcomes of a decision are unknown, the decision analysis defines a decision as having a higher risk. The case study method uses a compilation of case studies that maps out a supply network. In this map, risks are identified, assessed, and managed accordingly. It basically uses case studies of similar situations to determine what happened to other organizations in the same situation and gives an idea of the probability of risks that may affect the organization. Perception based risk analysis measures an organization's likelihood of experiencing unforeseen breakdowns, as well as their severity. The four classifications of risk severity are insignificant, minor, serious, and catastrophic. It also classifies the risk probability as very unlikely, improbable, probable, or very probable.
