Consider another comment from international accountancy firm Deloitte, quoting UK professor Margaret Heffernan: "Diversity ... isn't a form of political correctness but an insurance policy against internally generated blindness that leaves institutions exposed and out of touch." So why should you care? Because there's a mounting body of evidence that employing diversity policies is good for profits.
According to the Centre for American Progress, every company on Fortune magazine's list of the 100 best companies to work for includes sexual orientation in their non-discrimination policy.
GE Capital's experience is that, especially for mid-market companies, a diversity of experience and perspectives in the workforce will ensure there is better challenging - so you can harness the whole organisation to ensure your company doesn't make mistakes.
Every organisation needs different people with different perspectives. It is their background and experience that offer alternative views on projects or issues which create better decision-making and better organisational outcomes.
Companies should avoid "group think" - where there is no challenging or disagreement, as this is what helps people think outside the box. Different perspectives and a diversity of thought create this challenging element and help ensure your firm doesn't repeat mistakes.
GE Capital's experience in the mid-market company space is that many companies are struggling to find suitably qualified staff - particularly those companies in the smaller centres. We ask our clients: How are you facing this challenge? We share our experiences of firms that are doing it well.
Last words to Heffernan: "Imagine homogeneity of thought as leaders talking within an ideological echo chamber. While there may be debate and discussion, it has a limited range.
"What are the forces at work that make us deny the big threats that stare us in the face? What stops us from seeing that burying knowledge makes it more powerful, and us so much more vulnerable?"
