Choose the right perspective
Match the person's scope to your question: the chief procurement officer and vice president suit questions about procurement strategy and operating model, while global sourcing heads and category directors suit questions about one spend area such as R&D, manufacturing or commercial services. Check whether each Amgen role is current or past before asking about recent practice.
