TO DESIGN NEW QUALITY MODEL FOR EVALUATING COTS COMPONENTS

Abstract: The purpose of this paper is to build an ISO 9126 based new quality model that describes quality characteristics for the successful assessment of COTS software and to guide the industries that are making COTS-based systems. Some new features are added as well as some dropped in existing model ISO 9126 for better evaluation of COTS components. In the proposed model, some new sub-characteristic such as availability, resource utilization, and capacity associated with high-level characteristic efficiency (performance) are included. Some new sub-characteristics are also added such as scalability, reconfigurability, stability, and self-contained.Keywords: COTS, Quality model, ISO 9126, Component-Based Software Development (CBSD)
