Feature analysis for architectural evaluation methods

Given the complexity of today’s software systems, Software Architecture is a topic that has recently increased in significance. It is consider as a key element in the design and development of systems and has the ability to promote/punish some quality characteristics. Quality is related mainly to the non-functional requirements expected of the system. Using appropriate methods for Architectural Evaluation can help to reduce the risk of low quality Architecture. The objective of this research is to conduct a Features Analysis for three Architectural Evaluation Methods applied to a single case. This resulted in two significant contributions; the aspects which must be present in an architectural evaluation method which is translated in a set of 49 metrics, grouped into features and sub-features to enable the evaluation of a particular method. Different methods can be compared on the basis of these features; however, the choice of method will depend largely on the requirements of the evaluating team. The second contribution pinpoints the strengths of the methods evaluated. The methods studied were: Design and Use of Software Architectures, Architecture Tradeoff Analysis Method, and Architectural Evaluation Method. The evaluation method employed for this research was Features Analysis Case Study. 2005 Elsevier Inc. All rights reserved.
