Is Diversity is about having the best thinking?

Former Mitie Group CEO Ruby McGregor-Smith, who was the first Asian female chief executive of any FTSE 100 or FTSE 250 company, writes in the Telegraph about workplace diversity.

She says businesses must set aspirational targets for diversity to ensure it reaches senior levels and also need to be aware of "unconscious" bias against applicants. "Diversity is about thinking, it's not about whether you're black, or disabled or a woman - it's about having the best thinking around you," she says.
