An Architectural Decision Tool Based on Scenarios and Nonfunctional Requirements

Software architecture design is often based on architects intuition and previous experience. Little methodological support is available, but there are still no effective solutions to guide the architectural design. The most difficult activity is the transformation from non-functional requirement specification into software architecture. To achieve above things proposed "An Architectural Decision Tool Based on Scenarios and Nonfunctional Requirements". In this proposed tool scenarios are first utilized to gather information from the user. Each scenario is created to have a positive or negative effect on a non-functional quality attribute. The non-functional quality attribute is then computed and compared to other non-quality attributes to relate to a set of design principle that are relevant to the system. Finally, the optimal architecture is selected by finding the compatibility of the design principle.
