What questions must be addressed in Architectural Design?

1) Is there a generic application architecture that can act as a template for the system. 2) How will the system be distributed across a number of processors? 3) What architectural patters might be used? 4) What will be the fundamental approach used to structure the system? 5) How will the structural components in the system be decomposed into sub-components. 6) How will the architectural design be evaluated? 7) How will the architecture of a system be documented?
