Two software architecture evaluation methods based on scenario

Software architecture evaluation methods switch quality demand to interaction between risk-receivers and the system. Advancing evaluation could reduce quality risk when software is designed. SAAM and ATAM were two different evaluation methods which all have their merits when applied in creating scenario, describing business motivation and software architecture and so on. Both methods canpsilat ensure certainty when applied in particular performance, so it is an effective way to combine quantitative methods and scenario qualitative evaluation.
