\A supply manager is developing a supply risk management plan. Upon review of the current strategic sourcing plan, it is learned that many single-sourced items are delivered on a just-in- time basis. Which of the following is the BEST course of action for the supply manager to take in order to determine whether to change the current sourcing plan? Reduce or eliminate current supplier risk by ensuring that there is more than one source for each critical supply item. Ask the manufacturing/operations manager to estimate how much risk can be allowed for each critical supply item. Conduct a risk assessment to determine the cost impact if an item is unavailable and the savings potential from the current sourcing strategy. Determine the probability of a supply risk interruption and advise the finance department of the potential impact on the company financial statement
