The requirements modeling activity is iterative: As the model proceeds from an abstract to detailed definition of the system, refinement of the higher-level abstractions might identify new or different partitionings of flows, processes, or both. Similarly, the architecture modeling activity is iterative: As the requirements model is allocated to specific architecture modules, the refinement of this allocation might identify new or repartitioned modules that better meet the system’s ...
