Quality-Driven Architecture Design and Quality Analysis Method. A Revolutionary Initiation Approach to a Product Line Architecture

摘要

The role of software architecture had changed. The use of modern software technologies and practices enables turning the focus of system development to the quality aspects of software instead of functional properties. Architecture addresses the quality issues of software and, therefore, it must be developed and documented properly. In particular, there is a need for high level architectural descriptions. The top down nature of software architecture design induces this need. In this report, the authors introduce a quality-driven architecture design and analysis (QADA) method. Quality-driven is about utilizing architectural styles and patterns as a means of designing high-quality architectures. QADA takes a revolutionary approach to the initiation process of a new product line. That is, the development of a complete product-line architecture and a set of components before developing the first product in a new domain. QADA considers architecture on two levels of abstraction: conceptual and concrete.
