Mixtures are More Resilient
Purity is nice, but a mixture is more resilient. For example, the Parker Solar probe would have burned up if it were made from pure elements. Pure substances are almost always less resilient than a mixture. In business, the same is true: a mixture of people while less efficient, is more resilient. Many businesses say they value diversity, but do not have the structures in place to achieve the diversity they want. Part of the problem is that diversity costs and the benefits take time to be realized.
Many people like to go for pure. A diamond, as pure carbon, burns around 1,000 degrees. Many a beginner jewelry maker has lost a diamond by putting it in a furnace to work on the metal holding it only to have the diamond burn up.
Compare that with the Parker Solar probe with its 4 1/2 inch carbon composite shield. Now, it has survived five passes very close to the sun's surface passing through temperatures of almost 2,500 degrees F. It has one instrument sticking out to measure the solar wind.
No single metal is able to survive these extremes. Every part of that one instrument is built from a mixture of metals and that mixture is far stronger than any one of the metals mixed in. By mixing a number of other elements, we build something that can withstand the extremes.
A number of businesses have been built by pulling in like-minded people - only to fail when conditions changed. For example, a number of people left Apple to join J.C. Penney bringing with them the ideas and concepts that worked for Apple. But, the conditions at J.C. Penney were quite different and the same thinking nearly destroyed the company.
Many a venture capitalist has seen a "pure" startup team built of people with the same skills as the founder. The investor restructures the team to have a more balanced set of talents knowing that such "pure" teams won't survive. However, they have rarely challenged any racial or gender "pure" teams because they have not seen the difference that racial and gender diversity bring.
Building a more diverse team and more diverse management takes both time and money. A short-term focus keeps corporations from investing in diversity. There are costs to diversity; costs in terms of misunderstandings, cross purposes, and other conflicts. But the payoff comes from finding new products and services, finding new markets, and surviving changing situations.
In order to build diversity, a business needs to identify how such investment actually will pay off for them. Diversity has proven to generate a lot higher innovation revenue per company and helps cities survive. It isn't that one "diverse" person generates that innovation, but the interactions between diverse people do. Once these payoffs are identified, then a plan can be put into place with metrics and accountability to ensure that the interactions happen.
