I. A well-designed software architecture forms the basis for software that can perform in the long term. International Journal of Software Engineering and Knowledge Engineering Vol. Evaluating architectures is dijjicultfor two main reasons. These design decisions are described in terms of the eight software architectural patterns dis-cussed by Buschmann and colleagues in . 1. An architect needs tools to tackle this. 453-478 (2001) Special Issue: Software Architecture; Guest Editor: Rick Kazman No Access VIEWPOINTS ON MODIFIABILITY The effort, and therefore cost, that is required for these modifications is largely determined by a system's software architecture. Definitely, any degeneration needs extra effort and delays the releases of the system. The architects are influenced by which of the following factors? Modifiability can be defined as the ease with which changes can be made to a system, and the flexibility at which the system adjusts to the changes. Request PDF | Designing Modifiability in Software Architectures | In this chapter, we present modifiability as an architectural quality and how to express modifiability in software architecture. Professor of Computer Science " At Carnegie Mellon University since 1990 " Before then in industry (test and measurement) !
