The document discusses the invisible barriers that hold women back from advancing into senior leadership roles despite corporate commitments to diversity, such as entrenched beliefs among managers that subtly hamper women's careers, and it proposes a hard-edged approach of systemwide change driven by targets, data-driven performance reviews, and genuine sponsorship to help companies overcome these problematic mindsets. It also examines data showing the leaky talent pipeline for women and common explanations given for failing to retain or promote promising women.
