Abstract

To sustain the qualities of a software system during evolution, and to adapt the quality attributes as the requirements evolve, it is necessary to have a clear software architecture that is understood by all developers and to which all changes to the system adheres. This software architecture can be created beforehand, but must also be updated as the domain of the software, and hence the requirements on the software system evolves. Creating an architectural structure for a system or part of a system so that the architecture fulfils the desired quality requirements is often hard. In this paper we propose a decision support method to aid in the understanding of different architecture structure candidates for a software system. We propose a method that is adaptable with respect to both the set of potential architecture structures, and quality attributes relevant for the system's domain to help in this task. The method creates a support framework, using a multi-criteria decision method, supporting comparison of different software architecture structures for a specific software quality attribute and vice versa. Moreover, given a prioritization of quality attributes for the software system, or part thereof, the most suitable software architecture structure can be indicated using the created framework.
