Decision quality increases with the number of available options. The MG RUSH technique has long promoted the concept of teams to improve decision quality.  Most understand that properly facilitated teams are smarter than the smartest person on the team, especially with diverse teams.

  1. Teams create more options than aggregating individual inputs.
Four Reasons You Will Dial Up Decision Quality with More Diverse Teams

Dial-Up Decision Quality with More Diverse Teams

Diverse teams push even higher, why?

A 2015 McKinsey study found that among nearly 400 public companies in the top quartile for ethnic and racial diversity in management, they were 35% more likely to have financial returns above their industry mean.  An additional positive factor was found for gender diversity as well. Credit Suisse found among 2,400 global companies that “organizations with at least one female board member yielded a higher return on equity and higher net income growth than those that did not have any women on the board.”[1]

In addition to decision quality mentioned above, a November 2016 HBR (Harvard Business Review) article by David RockHeidi and Grant Halvorson provides three additional reasons to promote diversity within your teams:

  1. Assuredly, diverse teams rely more on facts,
  2. And diverse teams process facts more carefully,
  3. Consequently, diverse teams are more innovative

With some strong research to back them up, the rationale for each follows.

Diverse Teams Rely More On Facts

When teams and groups are stirred up with heterogeneity, they find common ground in facts. Ethnically diverse groups make more accurate predictions than homogeneous groups. Because they focus less on the subjective feelings of individuals, they present arguments that belie the objective nature of the group at large. Therefore, by mixing up groups, participants become more aware of their own biases and heuristics.

“Diverse teams are more likely to constantly reexamine facts and remain objective. They may also encourage greater scrutiny of each member’s actions, keeping their joint cognitive resources sharp and vigilant.”

Diverse Teams Process Facts More Carefully

Increased diversity forces teams to take a more disciplined approach to analyzing information. Referring to a study published in the Personality and Social Psychology Bulletin by Katherine Phillips of Northwestern University, groups with ‘newcomers’ were more likely to make accurate decisions than those without.

“Remember: Considering the perspective of an outsider may seem counterintuitive, but the payoff can be huge.”

Diverse Teams Are More Innovative

Innovation drives superior profits and customer lifetime value. The authors refer to a study of over 4,000 companies published in Innovation: Management, Policy & Practice.

“ . . . they found that companies with more women were more likely to introduce radical new innovations into the market over a two-year period.”

Separately, a study of nearly 8,000 firms in the UK indicates clearly that diverse leadership teams are more likely to develop new products. Therefore, according to RockHeidi and Halvorson:

“Hiring individuals who do not look, talk, or think like you can allow you to dodge the costly pitfalls of conformity, which discourages innovative thinking.”

While the HBR article emphasizes the enrichment of employee pools by varying gender, race, and nationality, you should aspire for heterogeneity among your teams and meetings.  Divers teams monitor personal bias and validate assumptions more thoroughly.  As you facilitate and lead meetings with higher quality decisions and output, your projects will and programs will more likely succeed as well.
