In organisation design lots of effort are put in the workings of an organisation, assuring that it delivers the output as planned and in a way as foreseen. Functionality is the major and often the only parameter for the design of an organisation.
For really great design that functionality is obvious. It is just there. The true value lies in other aspects of the design. And this value remain even when the original functios has changed.
These values need to be explicitly incorporated in the design process, even at the expense of one dimensional functionality in order to create lasting beauty.
All the buildings of Palladio have seen change in their original functional setting, yet they remain true proof of the genius of their designer and have kept their intrinsic qualities up to the present age.
