Bridging the Gap between Requirements Engineering and Software Architecture : A Problem-Oriented and Quality-Driven Method

This book systematically identifies the lack of methodological support for development of requirements and software architecture in the state-of-the-art.To overcome this deficiency, the QuaDRA framework is proposed as a problem-oriented approach.It provides an instantiation of the Twin Peaks model for supporting the intertwining relationship of requirements and software architecture.QuaDRA includes several structured methods which guide software engineers in quality- and pattern-based co-development of requirements and early design alternatives in an iterative and concurrent manner.
