Play to Win Behaviors
Play to Win is our corporate strategy, a concept that aligns our way of working and shows us a clearer vision when it comes to achieving objectives and is based on four behaviors:
Stretch: I try new things, even if it feels uncomfortable. I take calculated risks.
Take action: I focus on what is important now, and follow-up on what can be improved.
Act for patients & customers: I strive to free up time and/or budget that can be reinvested in our pipeline. I make sure what we do is in direct support of our science, strategy, market, patients, and/or customers.
Think Sanofi first: I seek what is best for Sanofi rather than best for myself or my team/function/GBU and I dare to challenge my boss and my team if I feel we don’t.
