Pollen is easy to overlook. 

It drifts unnoticed through the air, carried from one place to another, connecting things that would otherwise remain separate. By itself it appears insignificant. Yet almost every landscape we value depends on it.

Ideas behave in much the same way. 

The ones that change organisations rarely arrive with fanfare. More often they begin as a quiet observation, a conversation between colleagues or a different way of framing an old problem. They move from person to person, gathering momentum until they become accepted as if they had always been there.
