—Software architecture decision-making is critical to the success of a software system as software architecture sets the structure of the system, determines its qualities, and has farreaching consequences throughout the system life cycle. The complex nature of the software development context and the importance of the problem has led the research community to develop several techniques, tools, and processes to assist software architects in making better decisions. Despite these effort, the adoption of such systematic approaches appears to be quite limited in practice. In addition, the practitioners are also facing new challenges as different software development methods suggest different approaches for architecture design. In this paper, we study the current software architecture decisionmaking practices in the industry using a case study conducted among professional software architects in three different companies in Europe. As a result, we identified different software architecture...
