An architectural design selection tool based on design tactics, scenarios and nonfunctional requirements

This paper discusses a method and its supporting tool to select the software architecture for a family of software systems (commonly known as architectural styles) that meets the needs of the user. Our approach emphasizes the importance of basing architecture on non-functional requirements (NFRs). To this end, we have utilized a scenario-based approach that will determine NFRs of software architecture. NFRs are then mapped to optimal software architecture of a system by a set of table. Tables are applied to properly bridge the gap between NFRs and its corresponding software architecture.
