Design and Evaluation of New Reusability Metrics Based on Fuzzy Approach to Measure the Quality of Component Based Software

Abstract

newlineWith the growing need of software for frequently changing computer gadgets and smart applications, the quality and productivity of software become very important for software companies. The demand of quality software development within less time is increasing day by day. This need leads towards the reusability approach which reduces development efforts and assures good quality software more efficiently. Component-Based Software Engineering (CBSE) supports the practice of building software from the pre-existing component or third party software Component-Off-The-Shelf (COTS). This approach caters the increased demand in particular when this is done using reusable software components. CBSE has established itself as a competent technology to achieve high quality software with higher reusability. The reusability is an ideal and key factor to improve the quality and production rate of software. The quality assessment of software processes and products has been always a thrust area for the software engineering researchers. It becomes very helpful for quality assurance if such quality parameters can be quantified. Non-functional quality parameters like reusability are not easy to measure and quantify. This study would help to manage the quality assurance by measuring reusability which is a significant attribute of software quality. This study helps in analysis, design, and development of reusability metrics to complete the demand of good reusable software components in the software industry. A reusability metrics for proper quantification of the quality characteristic reusability is proposed. This reusability metrics considers five factors: coupling, interface complexity, understandability, customizability, and reliability.
