This can inform high-level decisions on specific areas for software improvement. The aim of architecture evaluation is “to analyze the software architecture to identify potential risks and verify that the quality requirements have been addressed in the design” [ 13 ]. These decisions ultimately impact application quality, maintenance, performance and overall success. On the one hand, the analysis discovers potential risks and areas for improvement; on the other hand, it can raise confidence in the chosen architectural approaches. :�P�8����z) ���P]3��ґ�M�9�|���Ϙf�W�Gp��n^ ��8����v�ގ!��(T�k�̨֜L�ϲk�P�Ph�����Y]�3�f�1B��rA9�����KԸ���9�@u8�#F��)g�s(��L�ض���������)�A�(B��ćYa��ě#���%�s "�|�l���f��d�=F5C&���H�FUyCwOXzy+HY�R6��m� *G�3����m�~�tV�¯[4� The idea is to look closely at the resources and tools provided by the software that is either currently in use or is being examined as a possible addition to programs already in use by that client. 7 0 obj Metric-based Evaluation of Software Architecture for an Engine Management System As such, it can be used to describe both the software architecture 's organization (a design pattern or architectural pattern) and the software process' organization (a software process model). 2. 1. %%EOF

Software architecture evaluation is the analysis of a system's capability to satisfy the most important stakeholder concerns, based on its large-scale design, or architecture (Clements et al., 2002). It can be defined as the set of structures needed to reason about the software system, which comprise the software elements, the relations between them, and the properties of both elements and relations.
