  The design phase plays a vital role than all other phases in the software
development. Software Architecture has to meet both the functional and
non-functional quality requirements. The Evaluation of Architecture has to be
performed, so that the developers are assured that their selected Architecture
will reduce the cost and effort and also enhances the various quality
attributes like Availability, Reusability, Performance, Modifiability and
Extendibility. The success of the system depends upon the Architecture
Evaluation by the essential method to the system. The overall ranking of the
candidate architecture is ascertained by assigning weight to the scenario and
scenario interaction. In this paper, SAAM method is taken to evaluate the two
architectures from the various available method and techniques to achieve the
various quality attributes by weight metric.
