Design optimization metrics for UML based object-oriented systems

Design plays a key role in the development of software. The quality of design is crucial and is a fundamental decision element in assessing the software product. The early availability of design quality evaluation provides a better way to decide the quality of the final product. This avoids presumption in the quality evaluation process. Hence Software Metrics provide a valuable and objective insight of enhancing each of the software quality characteristics. This paper proposes a quality model to assess the design phase of any object-oriented system based on the works of Chidamber, Kemrer and Basili and suggests two new metrices. Teh research focuses on analyzing a set of metrices, which has direct influence on the quality of the software and creating a metrices tool based on Java that is carried out on a set of real world projects designed using Unified Modeling Language, which are used as test cases. These metrices and models are proposed to add more quality information in refining any object-oriented system during the early stages of design itself.
