Culture evolves with people.  Failing to adapt can lead an organization to homogeneity.  Not having a diversity of ideas can cause groupthink and stunt your growth.

Regardless of a business’s clear goals and strong profits, a culture needs to adapt to the changing needs of its people.  The moment that diverse teams become homogeneous and categorical you lose flexibility.  They might be easier to manage but they can turn people away and limit productive conversations across business units.
