software architecture evaluation methods

Software architecture evaluation is the analysis of a system's capability to satisfy the most important stakeholder concerns, based on its large-scale design, or architecture (Clements et al., 2002). 0000006472 00000 n Recently, a number of new scenario-based software architecture evaluation methods have been developed by different academic groups and published in form of books or doctoral dissertation theses. 0000001331 00000 n Architecture Trade-Off Analysis Method (ATAM), Architecture Review of Intermediate Design (ARID) and Software Architecture Analysis Method (SAAM) are some of the well known methods for architecture evaluation. in their work, Framework Classification and Comparison of Software Architecture Evaluation Methods, has proposed a reliable framework for software architecture evaluation method. read The SEI Quality Attribute Workshop The methods are illustrated both by case studies and by sample artifacts put into play during an evaluation: viewgraphs, scenarios, and final reportsâeverything you need to evaluate an architecture in your own organization. Architecture evaluation is an approach for assessing whether a software architecture will be complete and consistent in terms of non-functionalthe system needs, especially the requirements (also known as quality requirements). }, Carnegie Mellon University Software Engineering Institute 4500 Fifth Avenue Pittsburgh, PA 15213-2612 412-268-5800, Enterprise Risk and Resilience Management, Computer Security Incident Response Teams, Architecture Tradeoff Analysis Method Collection, Evaluating Software Architectures: Methods and Case Studies.

This book is a comprehensive, step-by-step guide to software architecture evaluation, describing specific methods that can quickly and inexpensively mitigate enormous risk in software projects. Methods in the categories can be used independently but also be combined to evaluate different aspects of software architecture, if needed [8]. While there are numerous reviews and discussions on class-level metrics reported in literature [24, 57], there is no systematic review on metrics-based software architecture evaluation methods. A prototype-based evaluation method is proposed that enables evaluation of multiple quality attri- butes using components of a system and an ap- proximation of its intended run-time environment. Evaluations represent a wise risk-mitigation effort and are relatively inexpensive. 0000000016 00000 n Software architectural evaluation becomes a familiar practice in software engineering community for developing quality software. 35 4. 0000000696 00000 n Metrics. 0000003668 00000 n 0000001843 00000 n endstream endobj 36 0 obj<> endobj 37 0 obj<> endobj 38 0 obj<>/ProcSet[/PDF/Text]/ExtGState<>>> endobj 39 0 obj<> endobj 40 0 obj<> endobj 41 0 obj<> endobj 42 0 obj<> endobj 43 0 obj<> endobj 44 0 obj<> endobj 45 0 obj<> endobj 46 0 obj<>stream 0000001040 00000 n 0000003350 00000 n 35 0 obj <> endobj The software architecture community has developed many frameworks for eliciting, structuring, and classifying scenarios, such as Lassing et al.âs two-dimensional frame-work for Vikranth Vaddi 2.

Software architecture (SA) evaluation is a quality assurance technique that is increasingly attracting significant research and commercial interests. 35 20 [3], the software architecture evaluation methods are In this paper, we present a survey of software architecture evaluation methods. Surveying software architecture evaluation methods has, as far as we know, been done in four previous studies. Travis Stude 5. The purpose of the architecture evaluation of a software system is to analyze the architecture to identify potential risks and to verify that the quality requirements have been addressed in the design.
