McKinsey’s latest study of diversity in the workplace, Delivering through Diversity, reaffirms the global relevance of the link between diversity—defined as a greater proportion of women and a more mixed ethnic and cultural composition in the leadership of large companies—and company financial outperformance. The new analysis draws on data of more than 1,000 companies covering 12 countries, measuring not only profitability but also longer-term value creation, exploring diversity at different levels of the organization, and providing insight into best practices. Yet progress on diversification initiatives has been slow and companies are still uncertain about how they can most effectively use diversity and inclusion to support their growth and value-creation goals. To address these uncertainties, the report also provides a perspective on how to take action on inclusion and diversity to impact growth and business performance as well as tangible case studies.
