A February 2008 conference brought together software engineering practitioners and researchers from industry and academia to exchange experiences and ideas related to aspects of software architecture. Research papers, experience reports, case studies, and working sessions from the conference are collected here, reflecting perspectives from across the discipline. Some major themes examined are management, patterns and styles, requirements and design, architecture and organization, analysis and design, architecture documentation frameworks, generation and transformation, and architecture and adaptation. Some specific topics include simulation of software architectures for functional analysis, extraction of component-based architecture from object-oriented systems, teaching software architecture design, and the role of dependency links in ensuring architectural view consistency.
