The importance of Software Architecture (SA) design has been acknowledged as a very important factor for a high-quality software development. Different efforts in both industry and academia have produced multiple system development methodologies (SDMs) that include SA design activities. In addition, standardization bodies have defined different recommendations regarding Software Architecture design. However, in industry Software Architecture best practices are currently poorly employed. This fact constrains the benefits that industry can potentially obtain from Software Architecture design in software development. In this paper, we analyze the degree to which the four main recognized SDMs — RUP (Rational Unified Process), MSF (Microsoft Solutions Framework), MBASE (Model-Based System Architecting and Software Engineering), and RUP-SOA (Rational Unified Process for Service-oriented …
