A gradually proceeded software architecture design process

When design software architecture for large systems, designers often face with the problem how to move from requirements to a coarse-grained abstract architecture, then gradually refine it into more concrete ones, and last to detail design and implementation. Steps involved to implement such a process remain vague. Designers usually implement this process intuitively and opportunistically. We propose a Gradually Proceeded Software Architecture Design Process called GADesign. GADesign divides software architecture design into several phases and provides a sequence of well-defined steps to make this process more transparent and easier to be implemented.
