In companies that have more women among their senior ranks, that increased presence clearly has an impact on performance. We consider the averages. Of course, we could choose companies with many women in senior positions that are performing poorly. However, generally speaking, the average economic performance is higher when more women occupy senior positions.
Moreover, if more women—three and above—are on a company's board of directors, over a five-year period, the same changes are noted within the executive committee and the organization. We don't know exactly why this is, but it is clear that cultural changes are occurring in the organization.
Although there isn't much research to definitively confirm this principle, common sense says that an individual dealing with a complex problem will definitely not select as external advisers five individuals who think, reason and present their positions exactly like them. When dealing with a complex problem, it is clear the person will seek different opinions that reflect different perspectives in order to make the right decision.
That's exactly the personal experience that has been shared with us by people who are represented on executive committees and boards of directors.
