Choose the right perspective
Match the person's scope to your question: network-level vice presidents suit questions about running many plants and product platforms, while site leaders and manufacturing directors suit questions about running a single plant day to day. Consider the product type as well, since biologics, sterile injectables and oral solids plants are run differently.
