This paper presents Software Architecture Risk Assessment (SARA) Tool to demonstrate the process of risk assessment at the software architecture level. The prototype tool accepts different types of inputs that define software architecture. It parses these input files and produces quantitative metrics that are used to estimate the required risk factors. The final result of this process is to discern the potentially high risk components in the software system. By manipulating the data acquired from domain expert and measures obtained from Unified Modeling Language (UML) artifacts, SARA Tool can be used at the architecture development phase, at the design phase, or at the implementation phase of the software development process to improve the quality of the software product.
