Deloitte Thinks Diversity Groups Are Passé

It seems to me they're focusing on the wrong thing. See here:

“A lot of our leaders are still older white men, and they need to be part of the conversation and advocate for women. But they’re not going to do that as much if they don’t hear the stories and understand what that means.”

This doesn't necessitate adding white men to these groups but rather making sure that leaders of all stripes interact with these groups.

They're both necessary. There should be diversity groups to ensure that people have a voice and then inclusion councils to make sure that they're heard by people who need to hear them most.
