Hello everyone. I am in the medical device industry and I find supplier management to be an area where the answers are not too clear-cut. I have some questions. What sorts of supplier controls can we place on single-source suppliers? If they are the only supplier available for the particular critical component we are looking for, what controls are available? On the other hand, for a critical component for which there are many suppliers, what sorts of controls can we place? Thanks. I look forward to any insight.
