In today's increasingly complex business world, organizations face pressure not only in terms of financial performance but also regarding social and environmental issues. Diversity, Equity, and Inclusion (DEI) have become key topics of discussion among business leaders, with their impact on financial performance being the subject of numerous studies. But does diversity actually translate into better business results? What factors determine an organization’s success in this area?
The Diversity Matters 2023 report, which analyzed 1,265 companies across 23 countries on six continents, provides clear conclusions: organizations with more diverse leadership teams achieve better financial performance. Companies that rank highest in gender diversity at the board level are 39% more likely to outperform the market average, compared to those that do not prioritize DEI. In terms of ethnic diversity, this likelihood stands at 27%.
Interestingly, companies where women make up more than 30% of the board significantly outperform those that do not reach this threshold. Conversely, organizations with low board diversity are 66% less likely to achieve above-average financial results.
Similar patterns emerge when looking at diversity in supervisory boards. Companies with a higher percentage of women in these roles are 27% more likely to achieve superior performance, while those with greater ethnic representation see a 13% higher chance of financial success.
Despite the positive research findings, simply increasing diversity is not enough to make an organization more effective. The key factor is how companies manage diversity and whether they are willing to make structural and decision-making changes to support inclusion.
Many organizations make the mistake of treating diversity as a one-time recruitment initiative, whereas real success comes from leveraging employees' diverse knowledge, experiences, and perspectives. Studies show that merely increasing representation from underrepresented groups does not automatically improve business efficiency—what truly matters is creating an environment where diversity becomes an asset.
As early as 1996, the Harvard Business Review introduced the learning-and-effectiveness paradigm, which argues that the real benefits of diversity come from building a learning-oriented organization that embraces cultural and identity differences. Companies that adopt this approach:
✅ Build a culture of trust – Employees must feel safe to express their opinions and experiences freely.
✅ Actively combat discrimination – Organizations need concrete policies that eliminate barriers to advancement and ensure equal opportunities.
✅ Give real decision-making power to diverse leaders – Only when leadership is truly diverse (in terms of gender, ethnicity, and experience) does diversity begin to deliver measurable business benefits.
Unlike traditional "inclusion slogans," this diversity management model requires deep structural changes in organizational hierarchy and decision-making processes.
Diversity in organizations positively impacts financial performance, but simply increasing the number of women or ethnic minorities in key positions is not enough. What truly drives success is implementing strategies that actively leverage diverse perspectives and experiences.
Companies that treat diversity as a strategic asset—and make meaningful changes to their organizational culture and decision-making structures—can not only boost financial performance but also gain a competitive advantage in an increasingly demanding business environment.
