software architecture evaluation methods

trailer Architecture Trade-Off Analysis Method (ATAM), Architecture Review of Intermediate Design (ARID) and Software Architecture Analysis Method (SAAM) are some of the well known methods for architecture evaluation. This book is a comprehensive, step-by-step guide to software architecture evaluation, describing specific methods that can quickly and inexpensively mitigate enormous risk in software projects. Methods in the categories can be used independently but also be combined to evaluate different aspects of software architecture, if needed [8].
