Form follows function or function follows form

From my understanding, FORM FOLLOWS FUNCTION is a principle associated with modern architecture and industrial design in the 20th century which states that the shape of a building or object should be predicated by or based upon its intended function or propose and the other one by the opposite. A building which come with good form will tend to attract people’s attention. 

Example : 

The r-pod is a perfect example of “form follows function”, with its unique shape and construction giving way to a 78” interior height! in term of form follows function, it manage to grab customer attention.

FUNCTION FOLLOWS FORM, Mies van der Rohe says that he did not stand against the form, but he think that form is a goal of the designing process. He also thinks that function follows form always end up with formalism, satisfied the building’s appearance from outside view, but we don’t know what will be happen inside.Tom Wright, one of the Atkin’s architect whom designed Burj Al Arab, said: “if you can draw a building with a few sweeps of the pen, and everyone recognizes not only structure but also associates it with a place on earth, you have gone a long way towards creating something iconic”. This is one of the examples of “function follows form” architect.

Example :  

This building was done by Frank Gehry. look at his work at MIT Strata Center. Iconic building with deconstructs style. But what happen next, MIT Sued Gehry much for that design.
