By reading through related articles on the topic I found that basically for a design to work, a person either use form or use function as their guiding design principles it goes both directions.
An example that I could think of is that for instance a glass is designed to be able of holding walter hence the form of the glass reflects the function of the liquid.
A problem discovered by a person named Curt Cloninger was that he found that when ‘form follows function’ it is as stating that every form that naturally exists in our world is present because of functional requirements. For example going backwards we start with the end result then we turn back to the origin of it and assume that the results were predictable. But there are actually reasons why something might have a particular form.
I believe the debate of this still goes on as most articles I read has their own saying for everything but if I was asked this question whether FORM FOLLOWS FUNCTION or FUNCTION FOLLOWS FORM that im actually am being ask now which is why im writing this, I would most probably say that Function Follows Form. This is because I believe that one u are researching on one’s function particularly, a perfect idea of getting the form in comes directly next.
