Think about things differently.
Organisational Development (OD) is the approach of enabling enhanced organisational performance through the involvement of its people.
The greatest asset of any organisation are the people within it.
We define OD as two interconnecting and interdependent systems of interest; culture and structure.
Culture is abstract. It is the collection of beliefs, customs and social behaviours of a collection of people.
You don't change the culture, you change the underlying behaviours, attitudes and actions, and then culture emerges.
