Pfizer's mission is developing breakthrough medicines and bringing them to patients. Our strategy to execute on this mission depends on gathering the best ideas and using the sharpest science that the broader healthcare ecosystem can generate. Our past success has regularly been in partnership with others, and Pfizer is continuing to prioritize business development as core to our strategy. The Worldwide Business Development group supports Pfizer's external opportunities across commercial, development, research and platform technology opportunities. Pfizer's business unit and research unit structure promotes an entrepreneurial spirit, and gives each business unit the power and accountability to make decisions tailored to specific opportunities, in specific markets.
