Charles Darwin: “It is not the strongest species
that survive, nor the most intelligent, but the
ones most able to adapt to change.”
Organizations inspired by nature are resilient,
optimizing, adaptive, systems-based,
values-based, and life-supporting.
The more resilient an organization is, the
more able it is to successfully deal
With disturbances and volatility.
