It is one of the great unknowns. When a jury meets, it is unclear how events will develop.
Which member will play the leading role. Normally, the “guest star” is responsible for it. But that person arises, usually, by the choice of the contestants and it is not known until the architectural competition has been delivered.
In any architectural competition you have to make decisions. To make waivers. Doubts arise during the design process: what will be more valued by this jury? They are generic questions: what will be more taken into account, the use or the shape of the building? Or more specific What will they prefer, a wider lobby or more generous services?
