The article describes how Medical Affairs is evolving from retrospective, manually driven planning toward predictive, AI-enabled strategic design. As biomedical knowledge and data sources expand, traditional planning cycles struggle to keep pace. By integrating AI-powered analytics, literature mapping, unmet-need assessment, and predictive modeling, Medical Affairs shifts from reacting to scientific change to anticipating and shaping it. This transformation positions the function as a strategic intelligence engine—guiding proactive evidence generation, cross-functional alignment, and resource prioritization through continuous, insight-driven planning that augments human judgment with data-informed foresight.
