Reliability Estimation of Object-Oriented Software: Design Phase Perspective

This paper does a wide-ranging review on object oriented software Reliability, and put forth some appropriate information about design level Reliability. Reliability has been recognized as a major factor to software quality, an importance is being drawn to measure reliability early in development life cycle. In this study a metrics based Reliability Estimation Model for object oriented design has been developed. A suit of design metrics useful in measuring Reliability of software has been identified. Developed model measures the reliability of object oriented design in terms of „Effectiveness‟ and „Functionality. The study shows a relationship among „design properties with reliability key factors Effectiveness and Functionality in accordance with its anticipated weight and significance. Finally the developed model has been empirically validated and contextual interpretation has been drawn using industrial software projects.
