Introduction

Abstract

There exist two challenges in developing requirements and software architecture in current research for which satisfactory solutions are still sought. The first one refers to methods for building software architectures based on requirements. This task is even more challenging when software qualities have to be addressed in the software development. The other challenge refers to the process for bridging the gap between requirements and software architecture. This process is currently based on experience, communication, and intuition of software engineers. Such processes can hardly be used by novices and less experienced software engineers. This chapter outlines how this book aims to address the identified challenges by presenting the QuaDRA framework, which is a comprehensive approach for the iterative and concurrent co-development of requirements and software architecture with regard to quality requirements, in particular security and performance.
