Diversity, as defined by the Institute of Corporate Directors (ICD) in the Philippines, is the inclusion of more than one gender, age group, business expertise and experience, and other relevant attributes in the composition of a corporation's board. In advocating for board diversity, ICD contends that diversity in the boardroom promotes the inclusion of different perspectives and ideas, mitigates against "group think," improves oversight, and promotes informed decision-making and governance. Good corporate governance has been shown to correlate directly with corporate profitability and growth. Government and regulators require it. Companies of all sizes need it.
