Jack Rivkin's innovative approach to hiring, developing, and retaining employees created opportunities for female analysts to thrive at the equity research department he led, and also made the entire department more effective. Rivkin fostered a culture of gender inclusion and focused on developing the unique strengths of every employee, rather than expecting women to fit a rigid masculine norm. His efforts led to an increase in the department's female analysts and also resulted in more analysts (both women and men) achieving star-ranked status. In just a few years, the department jumped from 15th to 1st placed in industry rankings. However, when Rivkin departed, the overarching culture and practices of the firm undermined the inclusive environment he had fostered; high-performing analysts departed and the department rapidly tumbled in the rankings.
