Choose the right perspective
Match the person's product type to your question, since cell therapy, biologics, small molecule and medical device operations work very differently. Consider scope as well: network and supply chain leaders suit questions about planning across sites, while plant and site operations directors suit questions about running one facility.
Questions to take into the conversation
- 01How do you set priorities across safety, quality, supply and cost at a manufacturing site?
- 02What changes when a plant moves from launching a new therapy to running it at steady volume?
- 03How do site operations and the wider supply chain organization share decisions about capacity and planning?
