Taking this content from article “Photo synthesis: The agency tree” and putting here for my reference. Love the picture.
It talks of all the departments in an organization needs to collaborate and also shows the interdependence. Departments playing central role/non-customer role need to demonstrate more responsibility to hold things together and departments in customer facing roles need to equally contribute and help to sustain , grow and improve. A customer facing role cannot pull too strongly and make the tree fall. They need to work to make other sides strong and move along with them. if one side has a bigger pull, the other side will be weak and the tree won’t stand straight.
